OpenCV library build for esp-idf

This component used to build and include OpenCV library into the esp-idf as a component for esp32, esp32s2, esp32s3 and esp32p4 and esp32s3 CPUs. Now the opencv could be build with IDF version >= 4.4. This component was tested with opencv V 4.10.0.

More details about OpenCV can be found here.

To clone component from the github repository please follow a next command:

git clone https://github.com/espressif/esp-opencv-component.git espressif__opencv
cd espressif__opencv
git submodule update --recursive

The project has the following folders:

• opencv - OpenCV source code directory, added as git submodule
• opencv_contrib - additional modules for OpenCV, added as git submodule
• examples - directory with opencv examples running on Esp32-cam board.

The examples:

• 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.
