我正在使用 35MM EO 百万像素固定 FL 镜头 Edmund Optics 相机、OpenCV 2.4.6 和 Ubuntu 12.04 LTS 作为我的开发环境。我也在使用 C 来开发，而不是 C++。相机有一个我正在关注的 API，我相信我已经正确设置了所有内容。我初始化相机，设置内存位置，并冻结视频。然后我使用 OpenCV 从内存中获取图像，但我的图像与应有的不同（可能如下所示）。我的图像数据是否从垃圾内存位置提取数据？如何访问“is_FreezeVideo”保存的图像以供 OpenCV 完成图像处理？打印出来的图像可以在这里看到http://i.imgur.com/kW6aqB3.png
我正在使用的代码如下。
