相机采集到的图像输出格式是BGR，用OpenCV可以转成RGB

C++：

Mat image(Frame_t.iHeight, Frame_t.iWidth, CV_8UC3, (uchar*)Buffer_t);//从相机采集到的BGR24帧数据
cv::cvtColor(image, image, cv::COLOR_BGR2RGB);//通道顺序转换为RGB

Python：

import cv2  
   
src = cv2.imread(r'test.bmp') 
   
#image = cv2.cvtColor(src, cv2.COLOR_BGR2GRAY ) #转灰度
image = cv2.cvtColor(src, cv2.COLOR_BGR2RGB ) 
  
cv2.imshow("BGR2", image)

cv2.waitKey(0)
