This component used to build and include OpenCV library into the esp-idf as a component for esp32, esp32s2 and esp32s3 CPUs. Now the opencv could be build with IDF version >= 4.4. This component was tested with opencv V 4.7.0.
More details about OpenCV can be found here. The project has next folders:
opencv - OpenCV source code directory, added as git submodule opencv_contrib - additional modules for OpenCV, added as git submodule opencv_patch - folder with patch files for opencv and opencv_contrib examples - directory with opencv examples running on Esp32-cam board.
feature2d - extraction of 2d features form the camera image. motion_detection - example detect the motion on the picture from camera and print the coordinates of the object to the console. object_tracking - track the object located on center of the camera. people_detection - the example has to detect people on the image. text_area_detection - detect area on the image where text expected.
