如果两个 capture 都使用 cvCreateCameraCapture(-1),是可以切换到第二个摄像头,但当第二次执行 cvCreateCameraCapture() 函数时,会强行弹出选择摄像头的对话框要你手动选择,而且以后再添加摄像头的话,还得修改代码重新build,实际项目中肯定不能这样处理。在OpenCV中文论坛上找到的解释是,如果摄像头的名称是“USB...
接着,你需要初始化 MediaCapture 对象以使用在上一步骤中选择的帧源组,方法是设置 MediaCaptureInitializationSettings 的SourceGroup 属性。备注 使用OpenCV 处理软件位图中详述的 OpenCVHelper 组件采用的技术要求要处理的图像数据驻留在 CPU 内存中,而不是 GPU 内存中。 因此,应将 MediaCaptureInitializationSettings 的...
PiCapture Simple OpenCV wrapper for the Raspberry PI Camera Module This is based on Samarth Brahmbatt's code listed on his title: Practical OpenCV. Modified by George Profenza for a simpler/faster colour callback and added camera settings. The setter methods are minimally commented to include ...
