The created file should look like this, it can now be read by the ZED SDK. You can change to calibration flags or parameters as long as you respect the requested format and naming. The important point here is the output file format as the parameters are referred to by their names when loading them. Capture 1080p HD video at 30FPS or WVGA at 100FPS and get a crisp. Capture stunning 2K 3D video with best-in-class low-light sensitivity to operate in the most challenging environments. #include int main ( int argc, char ** argv ) else cout << "Error: can not save the extrinsic parameters \n " //-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ Using advanced sensing technology based on human stereo vision, ZED cameras add depth perception, motion tracking and spatial understanding to your application. The ZED SDK will automatically adapt the given calibration file to the requested camera resolution at runtime. ⚠ For better results perform your acquisition in FHD or 2K resolution. Here is a short C++ sample to record your calibration images. multiply various poses, close up, distant, tilted….the pattern should be fully visible in both the left and right images.at each pose, keep the camera still for a short period to avoid motion blur.put the calibration pattern in a clear area.the calibration pattern stays fixed, the camera moves around it.It is generated for each frame of the camera therefore the framerate depends on the framerate of the camera (You can setup the camera at a different resolution/FPS) 2) The ZED SDK offers a streaming module, based on RTP protocol and H264/5 encoding. ![]() It is recommended to first do the acquisition and save the images to later compute the calibration. 1) The depth map is generated by the host computer the camera is attached to. Once you have created your own calibration pattern you can perform your calibration acquisition. its marker size should be known and accurate.its size should be significant, A3 or more.it should be printed with accuracy, clear black and white, and no aliasing.it should be printed or stuck to a flat surface.You can refer to this page to create your own. We need a calibration pattern as a marker and as a world unit reference. Here are the steps to create your own calibration file. To enable this behavior, you have to specify an opencv calibration file as InitParameters::optional_opencv_calibration_file. Using your own calibration will not erase the factory calibration, it will just replace it at runtime if requested using the API. This feature was introduced in ZED SDK version 3.4. How to Calibrate your ZED camera with OpenCV CalibrationĮven though ZEDs are factory calibrated you may want to perform your own calibration and use its results in the ZED SDK.
