请问用openmv3识别二维码摄像头不是自动对焦的吗?我这里识别的二维码为什么这么模糊?

import sensor, image sensor.reset() sensor.set_pixformat(sensor.RGB565) sensor.set_framesize(sensor.QQVGA) # can be QVGA on M7... sensor.skip_frames(30) sensor.set_auto_gain(False) # must turn this off to prevent image washout... sensor.set_auto_whitebal(False) while(True): img = sensor.snapshot() img.lens_corr(1.8) # strength of 1.8 is good for the 2.8mm lens. for code in img.find_qrcodes(): print(code)

不是自动对焦的。需要手动对焦。
