推荐答案

从3.1开始，opencv imread可以完美处理exif方向.我知道这是一个老问题，但是最近我一直在努力寻找相同问题的答案，因此请在此处发布.显然，根据错误报告所述，cvLoadImage目前不能正确处理exif方向. github.

As of 3.1 opencv imread handles exif orientation perfectly. I know this is an old question, but I struggled to find an answer to this same question recently, so am posting here. Apparently cvLoadImage does not handle exif orientation correctly at this time according to a bug report on github.

您可以找到一组不错的示例图像，它们具有不同的exif旋转和很好的解释

You can find a nice set of sample images with different exif rotations and a good explanation here
