osg::Image转cv::Mat

找了很久，网上的都是osg::Image转IplImage的，而且试了不太对，后来参看http://forum.openscenegraph.org/viewtopic.php?p=50895#50895的转换代码，得到了想要的结果。

void imgosgtoopencv()

{

osg::ref_ptr<osg::Image> image = new osg::Image;

image = osgDB::readImageFile("girl_side1.jpg");

cv::Mat imgcv(image->t(),image->s(),CV_8UC3);

imgcv.data = (uchar *)image->data();

cv::flip(imgcv, imgcv, 0);

cv::cvtColor(imgcv, imgcv, CV_RGB2BGR);

cv::imshow("chang window",imgcv);

cv::waitKey(0);

}
