树莓派CM4+CS-MIPI-SC132 x2 运行python opencv报错

sjchen

由于CS-MIPI-SC132最大支持1280x1080，故修改capture2opencv脚本如下：

import D_mipicamera as Dcam
import time
import cv2 #sudo apt-get install python-opencv

def align_down(size, align):
    return (size & ~((align)-1))

def align_up(size, align):
    return align_down(size + align - 1, align)

if __name__ == "__main__":
    try:
        camera = Dcam.mipi_camera()
        print("Open camera...")
        camera.init_camera()
        while cv2.waitKey(10) != 27:
            frame = camera.capture(encoding = 'i420')
            height = int(align_up(1080, 16))
            width = int(align_up(1280, 32)) #修改了分辨率
            image = frame.as_array.reshape(int(height * 1.5), width)
            image = cv2.cvtColor(image, cv2.COLOR_YUV2BGR_I420)
            cv2.imshow("D-Cam", image)
            # Release memory
            camera.release_buffer(frame)
            del frame
        
        print("Close camera...")
        camera.close_camera()
    except Exception as e:
        print(e)

运行后报错： QQ截图20211217141752.jpg

除了你已经修改的地方之外，
需要用
D_init_camera_ex函数代替D_init_camera，这个函数具备分辨率的定义参数。
