在soc模式下，可以使用以下代码将cv::Mat对象转换为bm_image：```cpp #include "bmodel_interface.h"...
Mat转化为IplImage类型和CvMat类型 Mat转化为IplImage类型和CvMat类型 cv::Mat img; CvMat cvMatImg = img; IplImage IpImage = img; 转化后传递的是矩阵头。 IplImage类型转化为Mat和CvMat类型 IplImage *IpImage = cvLoadImage(“*.jpg”); Mat img(IpImage,true);...
转换为bm_image,如果你确实有一个原始OpenCV的cv::Mat,要转换为bm_image,那么你应当:创建一个有设备内存的Mat,然后使用Mat.copyTo将openCV的cv::Mat的系统内存拷贝到有设备内存的Mat的系统内存空间,然后使用cv::bmcv::uploadMat将有设备内存的Mat的系统内存同步到其设备内存,然后再调用toBMI将其转换为bm...
