关于opencv读取和写入路径有汉字的处理方式

 img_gt = cv2.imdecode(np.fromfile(path, dtype=np.uint8), -1)
 img_gt = cv2.cvtColor(img_gt, cv2.IMREAD_COLOR)

write_path=f'{save_dir}/{imgname}.jpg'
cv2.imencode('.jpg', output)[1].tofile(write_path)  # 保存图片

using namespace cv;
int main()

    std::string image_path = samples::findFile("D:\\素材\\1.png");
    Mat img = imread(image_path, IMREAD_COLOR);
    imshow("src", img);//原图像
    waitKey(0);
}

def readimg(filename, mode):

    img = cv2.imdecode(raw_data, mode)  #从内存数据读入图片
    return img
