I’ve bought your Multi Camera Adapter Module V2.2 for Raspberry Pi 4B and got that compiling error (after executing sudo python 4cam_cv2.py presented in instruction).
Attached pictures you could check the error message as well as the hardware connections.
Don’t worry . It seems it does not find the opencv lib. Have you installed the opencv lib firstly? just use the sudo apt-get install python-opencv command. Tomorrow I will test it and reply you as soon as possible.
Before running this demo. Please run the init_camera.sh to test if the hardware connection is normal. The script is at …/Multi_Camera_Adapter/Multi_Adapter_Board_4Channel/Multi_Camera_Adapter_V2.2/init_camera.sh path
Yes ive made it before testing the demo. Test was going OK: i have seen both camera previews (one after another, not both on monitor). But the demo and the raspicam module does not work.
