MYNT® EYE D SDK¶

PRODUCT¶

Product Description¶

The MYNT Depth utilizes the camera and the motion sensor to provide visually accurate SLAM results with higher precision, lower cost, simpler layout, along with the ability to achieve face and object recognition. The concept of combining binocular and IMU is the leading-edge technology in the current SLAM industry.The depth version of the product has a built-in depth calculation chip that can output depth images without the host computer. At the same time, the product is equipped with leading hardware solutions such as IR active light, IMU six-axis, hardware-level frame synchronization, global shutter, etc., up to 720p/60fps (120°FOV version) of synchronous image information, the recognition distance can reach 15m (50 °FOV version), accuracy up to millimeters (50° FOV version).

Using camera techniques such as frame synchronization, automatic exposure, and white balance control, the MYNT EYE Depth can produce synchronized image sources with high-precision, which decreases the difficulty of algorithms development, thus increasing efficiency. The Depth comes with six-axis sensor(IMU) and an infrared active light detector (IR). Among them, the six-axis sensor(IMU) can provide complementarity and correction of data from the visual positioning algorithms, and is suitable for visual inertial odometry(VIO) algorithms research to help improve the positioning accuracy. The infrared active light detector (IR) can help solve the problem of identification of objects such as indoor white walls and non-textured objects, as well as enhance the accuracy of image source recognition.The Binocular+IMU scheme provides accurate six-axis complementary data for VSLAM applications and is more accurate and robust than other single solutions. In addition, MYNT EYE Depth also provides a rich SDK interface and VSLAM open source project support, which can help customers quickly integrate solutions, accelerate product development process, and achieve rapid productization and implementation.

As a hardware product for in-depth research and development of stereo vision computing applications, MYNT EYE Depth can be widely used in the field of visual positioning navigation (vSLAM), including visual real-time positioning navigation system of driverless vehicle and robots, visual positioning system of UAV, obstacle avoidance navigation system for driverless Vehicle, Augmented Reality (AR), Virtual Reality (VR), etc. At the same time, it can be used in field of Visual recognition, including Stereoscopic face recognition, three-dimensional object recognition, space motion tracking, three-dimensional gestures and somatosensory recognition. And of course, you can use it for measurement which includes assisted driving system (ADAS), binocular volume calculation, industrial visual screening, etc.

In order to ensure the quality of the output data of the camera products, we have calibrated the binocular and IMU. The product has passed various hardware stability tests, such as high temperature and humidity continuous work and operation, low-temperature dynamic aging, high-temperature operation, low-temperature storage, whole-machine thermal shock, sinusoidal vibration and random vibration tests to ensure the stability and reliability of the product. In addition to the research and development of products and technologies, it can also be directly applied to mass production, accelerating the process from R&D to productization.

SDK Samples¶

Get Camera Image¶

Using the DeviceMode::DEVICE_COLOR function of the API, you can get color image，or use DeviceMode::DEVICE_ALL to get color and depth image.

Using GetStreamData() to get your data.

Reference code snippet:

// Device mode, default DEVICE_ALL
//   DEVICE_COLOR: IMAGE_LEFT_COLOR y IMAGE_RIGHT_COLOR - IMAGE_DEPTH n
//   DEVICE_DEPTH: IMAGE_LEFT_COLOR n IMAGE_RIGHT_COLOR n IMAGE_DEPTH y
//   DEVICE_ALL:   IMAGE_LEFT_COLOR y IMAGE_RIGHT_COLOR - IMAGE_DEPTH y
// Note: y: available, n: unavailable, -: depends on #stream_mode
params.dev_mode = DeviceMode::DEVICE_DEPTH;

auto left_color = cam.GetStreamData(ImageType::IMAGE_LEFT_COLOR);
    if (left_color.img) {
    cv::Mat left = left_color.img->To(ImageFormat::COLOR_BGR)->ToMat();
    painter.DrawSize(left, CVPainter::TOP_LEFT);
    painter.DrawStreamData(left, left_color, CVPainter::TOP_RIGHT);
    painter.DrawInformation(left, util::to_string(counter.fps()),
        CVPainter::BOTTOM_RIGHT);
    cv::imshow("left color", left);

Complete code samples，see get_stereo_image.cc .

Get Camera Image(Compatible With USB2.0)¶

Compatible with USB2.0 ,change to the resolution and frame rate for USB 2.0 automatically.Using the DeviceMode::DEVICE_COLOR function of the API, you can get color image，or use DeviceMode::DEVICE_ALL to get color and depth image.

Using GetStreamData() to get your data.

Reference code snippet:

// Device mode, default DEVICE_ALL
//   DEVICE_COLOR: IMAGE_LEFT_COLOR y IMAGE_RIGHT_COLOR - IMAGE_DEPTH n
//   DEVICE_DEPTH: IMAGE_LEFT_COLOR n IMAGE_RIGHT_COLOR n IMAGE_DEPTH y
//   DEVICE_ALL:   IMAGE_LEFT_COLOR y IMAGE_RIGHT_COLOR - IMAGE_DEPTH y
// Note: y: available, n: unavailable, -: depends on #stream_mode
params.dev_mode = DeviceMode::DEVICE_DEPTH;

auto left_color = cam.GetStreamData(ImageType::IMAGE_LEFT_COLOR);
    if (left_color.img) {
    cv::Mat left = left_color.img->To(ImageFormat::COLOR_BGR)->ToMat();
    painter.DrawSize(left, CVPainter::TOP_LEFT);
    painter.DrawStreamData(left, left_color, CVPainter::TOP_RIGHT);
    painter.DrawInformation(left, util::to_string(counter.fps()),
        CVPainter::BOTTOM_RIGHT);
    cv::imshow("left color", left);

Complete code samples，see get_image.cc .

Get Depth Image(Compatible With USB2.0)¶

In this sample you can learn how to display depth image and compute left camera coordinate from depth image.

You can change depth_mode to change the display of the depth image.

// Depth mode: colorful(default), gray, raw
params.depth_mode = DepthMode::DEPTH_RAW;

Then you can get it through GetStreamData().In addition, it should be check not be empty before use.

Reference code snippet:

auto image_depth = cam.GetStreamData(ImageType::IMAGE_DEPTH);
if (image_depth.img) {
  allow_count = true;
  auto &&depth_raw = image_depth.img->To(ImageFormat::DEPTH_RAW);
  auto &&depth_color =
      colorize->Process(depth_raw, ImageFormat::DEPTH_BGR)->ToMat();

  cv::setMouseCallback("depth", OnDepthMouseCallback, &depth_region);
  depth_region.DrawRect(depth_color);
  cv::imshow("depth", depth_color);

  // pass depth_raw to get real depth value
  depth_region.ShowElems<ushort>(
      depth_raw->ToMat(),
      [](const ushort& elem) {
        return std::to_string(elem);
      }, 80, depth_info);
}

The above code uses OpenCV to display the image. When the display window is selected, pressing ESC/Q will end the program.

Note

You can use function ToMat() to convert raw depth frame to other format such as gray and colorful(raw:CV_16UC1, gray & colorful:CV).

Complete code examples, see get_depth.cc.

Get Point Image¶

Point images belongs to upper layer of synthetic data.You can get it through GetStreamData().It should be check not empty before use. Otherwise, when running pionts,you can use “space” to save .ply files. Then sample view_points can be used to view .ply files.

Sample code snippet:

auto image_color = cam.GetStreamData(ImageType::IMAGE_LEFT_COLOR);
auto image_depth = cam.GetStreamData(ImageType::IMAGE_DEPTH);
if (image_color.img && image_depth.img) {
    cv::Mat color = image_color.img->To(ImageFormat::COLOR_BGR)
        ->ToMat();
    painter.DrawSize(color, CVPainter::TOP_LEFT);
    painter.DrawStreamData(color, image_color, CVPainter::TOP_RIGHT);
    painter.DrawInformation(color, util::to_string(counter.fps()),
        CVPainter::BOTTOM_RIGHT);

    cv::Mat depth = image_depth.img->To(ImageFormat::DEPTH_RAW)
        ->ToMat();

    cv::imshow("color", color);

    viewer.Update(color, depth);
}

PCL is used to display point images above. Program will close when point image window is closed.

Complete code examples, see get_points.cc.

Get IMU Data¶

You need EnableMotionDatas()to enable caching in order to get IMU data from GetMotionDatas().Otherwise, IMU data is only available through the callback interface, see Get Data From Callbacks.

Sample code snippet:

auto motion_datas = cam.GetMotionDatas();
if (motion_datas.size() > 0) {
    std::cout << "Imu count: " << motion_datas.size() << std::endl;
    for (auto data : motion_datas) {
        if (data.imu) {
            if (data.imu->flag == MYNTEYE_IMU_ACCEL) {
                counter.IncrAccelCount();
                std::cout << "[accel] stamp: " << data.imu->timestamp
                    << ", x: " << data.imu->accel[0]
                    << ", y: " << data.imu->accel[1]
                    << ", z: " << data.imu->accel[2]
                    << ", temp: " << data.imu->temperature
                    << std::endl;
            } else if (data.imu->flag == MYNTEYE_IMU_GYRO) {
                counter.IncrGyroCount();
                std::cout << "[gyro] stamp: " << data.imu->timestamp
                << ", x: " << data.imu->gyro[0]
                << ", y: " << data.imu->gyro[1]
                << ", z: " << data.imu->gyro[2]
                << ", temp: " << data.imu->temperature
                << std::endl;
            } else {
                std::cerr << "Imu type is unknown" << std::endl;
            }
        } else {
          std::cerr << "Motion data is empty" << std::endl;
        }
    }
    std::cout << std::endl;
}

OpenCV is used to display image and data. When window is selected, press ESC/Q to exit program.

Complete code examples, see get_imu.cc.

Get Data From Callbacks¶

API offers function SetStreamCallback() and SetMotionCallback() to set callbacks for various data.

Reference code snippet:

cam.SetImgInfoCallback([](const std::shared_ptr<ImgInfo>& info) {
    std::cout << "  [img_info] fid: " << info->frame_id
        << ", stamp: " << info->timestamp
        << ", expos: " << info->exposure_time << std::endl
        << std::flush;
});
for (auto&& type : types) {
    // Set stream data callback
    cam.SetStreamCallback(type, [](const StreamData& data) {
    std::cout << "  [" << data.img->type() << "] fid: "
        << data.img->frame_id() << std::endl
        << std::flush;
    });
}

// Set motion data callback
cam.SetMotionCallback([](const MotionData& data) {
    if (data.imu->flag == MYNTEYE_IMU_ACCEL) {
        std::cout << "[accel] stamp: " << data.imu->timestamp
        << ", x: " << data.imu->accel[0]
        << ", y: " << data.imu->accel[1]
        << ", z: " << data.imu->accel[2]
        << ", temp: " << data.imu->temperature
        << std::endl;
    } else if (data.imu->flag == MYNTEYE_IMU_GYRO) {
        std::cout << "[gyro] stamp: " << data.imu->timestamp
        << ", x: " << data.imu->gyro[0]
        << ", y: " << data.imu->gyro[1]
        << ", z: " << data.imu->gyro[2]
        << ", temp: " << data.imu->temperature
        << std::endl;
    }
    std::cout << std::flush;
});

OpenCV is used to display images and data above. When the window is selected, pressing ESC/Q will exit program.

Complete code examples, see get_from_callbacks.cc.

Attention: Now image resolution supports 4 types: 640X480,1280x720 for single camera. 1280x480, 2560x720 for left and right camera.

Reference code snippet:

// Stream mode: left color only
// params.stream_mode = StreamMode::STREAM_640x480;  // vga
// params.stream_mode = StreamMode::STREAM_1280x720;  // hd
// Stream mode: left+right color
// params.stream_mode = StreamMode::STREAM_1280x480;  // vga
params.stream_mode = StreamMode::STREAM_2560x720;  // hd

Set the frame rate of image¶

Using the params.framerate parameter, you can set the frame rate of image.

Note

The effective fps of the image(0-60) - The effective fps of the image in 2560x720 resolution (30)

Reference code snippet:

// Framerate: 30(default), [0,60], [30](STREAM_2560x720)
params.framerate = 30;

Set color mode¶

Using the params.color_mode parameter，you can set the color mode of image.

COLOR_RAW is original image， COLOR_RECTIFIED is rectified image.

Reference code snippet:

// Color mode: raw(default), rectified
// params.color_mode = ColorMode::COLOR_RECTIFIED;

Set depth mode¶

Using the params.depth_mode parameter，you can set the depth mode.

DEPTH_COLORFUL is colorful depth image，DEPTH_GRAY is grey depth image， DEPTH_RAW is original depth image。

Reference code snippet:

// Depth mode: colorful(default), gray, raw
// params.depth_mode = DepthMode::DEPTH_GRAY;

Enable auto exposure and auto white balance¶

Set params.state_ae and params.state_awb to true , you can enable auto exposure and auto white balance.

By default auto exposure and auto white balance are enabled，if you want to disable，you can set parameters to false .

Reference code snippet:

// Auto-exposure: true(default), false
// params.state_ae = false;

// Auto-white balance: true(default), false
// params.state_awb = false;

Enable IR and its adjustments function¶

Using the params.ir_intensity parameter，you can set IR’s intensity of image. Enabling IR is setting params.ir_intensity greater than 0. The greater the value, the greater the IR’s intensity.(max is 10).

Reference code snippet:

// Infrared intensity: 0(default), [0,10]
params.ir_intensity = 4;

Note

After turning this fuction on, you can see ir pattern:

Enable IR Depth Only¶

Using the params.ir_depth_only parameter，you can set IR Depth Only function. This is disabled by default. After turning this function on, IR only works on depth images. IR pattern will not show in color images.

Note

This feature is only available for [2560x720 30fps] and [1280x720,1280x480,640x480 60fps] After turning this function on, frame rate will be divided equally. For example, when set frame rate of image to 30 fps, the frame rate of color image is 15 fps. The frame rate of depth image is 15 fps too. This feature will cause the left eye image and depth map to be out of sync.

Reference code snippet:

// IR Depth Only: true, false(default)
// Note: IR Depth Only mode support frame rate between 15fps and 30fps.
//     When dev_mode != DeviceMode::DEVICE_ALL,
//       IR Depth Only mode not be supported.
//     When stream_mode == StreamMode::STREAM_2560x720,
//       frame rate only be 15fps in this mode.
//     When frame rate less than 15fps or greater than 30fps,
//       IR Depth Only mode will be not available.
// params.ir_depth_only = false;

Adjust colour depth value¶

Using the params.colour_depth_value parameter, The value is 5000 by default.

Reference code snippet:

// Colour depth image, default 5000. [0, 16384]
// params.colour_depth_value = 5000;

Camera Control Parameters API¶

Open or close auto exposure¶

/** Auto-exposure enabled or not  default enabled*/
bool AutoExposureControl(bool enable);    see "camera.h"

Open or close auto white balance¶

/** Auto-white-balance enabled or not  default enabled*/
bool AutoWhiteBalanceControl(bool enable);    see "camera.h"

Set infrared(IR) intensity¶

/** set infrared(IR) intensity [0, 10] default 4*/
void SetIRIntensity(const std::uint16_t &value);     see "camera.h"

Set global gain¶

Note

You have to close auto exposure first after opening camera.

/** Set global gain [1 - 16]
 * value -- global gain value
 * */
void SetGlobalGain(const float &value);    see "camera.h"

Set the exposure time¶

Note

You have to close auto exposure first after opening camera.

/** Set exposure time [1ms - 655ms]
 * value -- exposure time value
 * */
void SetExposureTime(const float &value);    see "camera.h"

Reference code snippet:

cam.Open(params);
cam.AutoExposureControl(false);
cam.SetGlobalGain(1);
cam.SetExposureTime(0.3);

Note

After changing the parameters, you need to run in the sdk directory

make samples

to make the set parameters take effect.

User filter to filter deep data¶

Filter type is inherited from BaseFilter .

Method port protocol is as follows：

virtual bool ProcessFrame(
      std::shared_ptr<Image> out,
      const std::shared_ptr<Image> in) = 0; // NOLINT
virtual bool LoadConfig(void* data);

inline bool TurnOn();
inline bool TurnOff();
inline bool IsEnable();


int main(int argc, char const* argv[]) {
...

SpatialFilter spat_filter;
TemporalFilter temp_filter;

...
for (;;) {
  // get frame
  ...
  spat_filter.ProcessFrame(image_depth.img, image_depth.img);
  temp_filter.ProcessFrame(image_depth.img, image_depth.img);
  ...
}

Tip

When using, instantiate a Filter ,then use it directly in the image processing loop ProcessFrame . The image will adapt to the image information in real time. You can also use the TurnOn/TurnOff switch in real time.

Record Data Sets¶

The SDK provides the tool record for recording data sets. Tool details can be seen in tools/README.md .

Reference run command on Linux:

./samples/_output/bin/dataset/record

Reference run command on Windows:

.\samples\_output\bin\dataset\record.bat

Reference run results on Linux:

$ ./samples/_output/bin/dataset/record
Saved 1007 imgs, 20040 imus to ./dataset
I0513 21:29:38.608772 11487 record.cc:118] Time beg: 2018-05-13 21:28:58.255395, end: 2018-05-13 21:29:38.578696, cost: 40323.3ms

I0513 21:29:38.608873 11487 record.cc:123] Imu count: 20040, hz: 496.983

Results save into <workdir>/dataset by default. You can also add parameter, select other directory to save.

Record contents:

<workdir>/
└─dataset/
   ├─left/
   │  ├─stream.txt  # Image infomation
   │  └─...
   ├─right/
   │  ├─stream.txt  # Image information
   │  └─...
   └─motion.txt  # IMU information

Tip

When recording data, dataset.cc has annotated display image inside cv::imwrite() . Because these operations are time-consuming, they can cause images to be discarded. In other words, consumption can’t keep up with production, so some images are discarded. GetStreamDatas() used in record.cc only caches the latest 4 images.

Save Device Infomation And Parameters¶

The SDK provides a tool save_all_infos for save information and parameters.

Reference commands:

./samples/_output/bin/writer/save_all_infos

# Windows
.\samples\_output\bin\writer\save_all_infos.bat

Calibration Tool Manual¶

Get Calibration Tool¶

Latest tool: mynteye-d-calibrator_1.0.zip Google Drive, Baidu Pan

Prerequisites(Update config file)¶

You can find Depth 50°’s config file in D1000-50 , Depth 120°’s config file in D1000-120 。
Config file in HD folder means using for 720p, VGA for 480p. You need calibrate both resolution for camera.
Copy and paste eDepthK.prj to mynteye-d-calibrator_1.0 folder.
Open eDepthK.prj with txt and modify Col1/2/3/4 to chessboard width, Row1/2/3/4 to chessboard height, Size1/2/3/4 to chessboard square size in meters.
Chessboard width and height refer to the number of black and white intersections in the horizontal and vertical directions of the checkerboard.

Example of 11x7 Intersection Chess Board¶

Parameters of eSPCalibrator¶

1.Open eDepthK.prj 2.Note that ‘Col1’ ‘Row1’ ‘Size1’ must match your chess board

Calibration Procedure 1 (Yoffset)¶

If you are calibrating VGA mode，please skip this procedure.
Calibration Process 1 need 1 picture.
The chess board must right in front of both camera and cover maximum portion(over 50%) of the preview image(try your best)
Press ‘c’ or ‘C’ to take the snapshot of the properly positioned chess board. If calibrator can not detect all the intersections on preview image, you will get “Not Found” result.

Operation guide¶

1.Double click mynteye-d-calibrator.exe 2.Press ‘c’ or ‘C’ to take the snapshot (total one frame)

Calibration Procedure 2 (Calibration)¶

Calibration need 5 pictures in 5 different angles
The required angles will be the combination of rotation along X and

Y axis. Each Rotation angle should be 10° to 30° and/or Y-axis around X- axis

The chess board must cover the maximum portion(over 50%)

of the preview image from both camera(try your best)

Press ‘c’ or ‘C’ to take the snap shot of the properly positioned chess board. If calibrator can not detect all the intersections on the chess board, you will get “Not Found” result.

Operation guide¶

Calibration Result¶

After calibration, parameters will auto write into device.

After caliobration, you can get Reprojection error in log file StereoSetting.txt , it is desirable to have a reprojection error of 0.2 or less. If exceeds 0.5, it needs to be recalibrated.

Log File¶

After caliobration, log file will save into Log_Folder .
