OpenCV常见数据类型

[图像处理]-Opencv中数据类型CV_8U, CV_16U, CV_16S, CV_32F 以及 CV_64F是什么?

ROS学习笔记–cv_bridge

CV_8U, CV_16U, CV_16S, CV_32F 以及 CV_64F，都是OpenCV定义的数据类型

图像编码可以是一下任意一种OpenCV支持的图像编码：

• 8UC[1-4]
• 8SC[1-4]
• 16UC[1-4]
• 16SC[1-4]
• 32SC[1-4]
• 32FC[1-4]
• 64FC[1-4]

对于某些常用的编码，CvBridge提供了可选的color或pixel depth的转换，要想使用这个特性，需要将编码指定为一下格式之一：

• mono8: CV_8UC1, grayscale image
• mono16: CV_16UC1, 16-bit grayscale image
• bgr8: CV_8UC3, color image with blue-green-red color order
• rgb8: CV_8UC3, color image with red-green-blue color order
• bgra8: CV_8UC4, BGR color image with an alpha channel
• rgba8: CV_8UC4, RGB color image with an alpha channel
