In Python, OpenCV stores images in NumPy arrays. Since the ZED SDK uses its ownsl.Matclass to store image data, we provide a functionget_data()to convert thesl.Matmatrix into a NumPy array. # Create an RGBA sl.Mat objectimage_zed=sl.Mat(zed.get_camera_information().camera_resolution....
To capture video, usegrab()andretrieveImage(). Sincesl::Matandcv::Matshare the same data, callingretrieveImage()will update the OpenCV matrix as well. Display the video with OpenCV usingcv::imshow(). if(zed.grab()==ERROR_CODE::SUCCESS) {// Retrieve the left image in sl::Mat// The...
After the refactoring, through the encapsulation of some opencv APIs, the framework and algorithms have been reorganized. At present, the effect feels good, and pr has been given to airtest, and the merger will be promoted in the future. Install opencv-python The suggested version can be 4.5....
