cv2.imread 读取中文路径的图片返回为None 问题解决记录

opencv不接受non-ascii的路径 因此尽量不要使用中文路径

若一定要使用,有如下解决办法:

先用np.fromfile()读取为np.uint8格式,再使用cv2.imdecode()解码。

cv2.imdecode(buf, flags)
# buf - Input array or vector of bytes.
# flags - The same flags as in cv2.imread().
#       - >0 Return a 3-channel color image.
#       - =0 Return a grayscale image.
#       - <0 Return the loaded image as is (with alpha channel).
# 读取图像,解决imread不能读取中文路径的问题
def img_read(file_path):
    image = cv2.imdecode(np.fromfile(file_path, dtype=np.uint8), 0)
    return image
