请尝试在Java中为匹配的图片和视频制作一个新的应用程序,图片中的模板匹配工作正常,但是当我尝试为视频做这件事时,我总是有这个错误消息:视频中的OpenCv匹配模板[Java]
OpenCV Error: Assertion failed ((depth == CV_8U || depth == CV_32F) && type == _templ.type() && _img.dims() <= 2) in cv::matchTemplate, file C:\builds\master_PackSlaveAddon-win64-vc12-static\opencv\modules\imgproc\src\templmatch.cpp, line 1062 Exception in thread "main" CvException [org.opencv.core.CvException: cv::Exception: C:\builds\master_PackSlaveAddon-win64-vc12-static\opencv\modules\imgproc\src\templmatch.cpp:1062: error: (-215) (depth == CV_8U || depth == CV_32F) && type == _templ.type() && _img.dims() <= 2 in function cv::matchTemplate ]
这是我的功能,用于匹配视频与图片,有人可以帮助请。
public int runVedio(String inFile, String templateFile, int match_method) {
int nbr = 0;
Mat templ = Imgcodecs.imread(templateFile);
VideoCapture capture=new VideoCapture(inFile);
Mat frame = new Mat();
Mat result = new Mat();
capture.read(frame);
///Do the Matching and Normalize
Imgproc.matchTemplate(frame,templ, result, match_method);
Imgproc.threshold(result, result,0.9,1,Imgproc.THRESH_TOZERO);
//Core.normalize(result, result, 0, 1, Core.NORM_MINMAX, -1, new Mat());
while(true)
{
///Localizing the best match with minMaxLoc
Core.MinMaxLocResult mmr = Core.minMaxLoc(result);
Point matchLoc;
if (match_method == Imgproc.TM_SQDIFF || match_method == Imgproc.TM_SQDIFF_NORMED) {

Imgproc.rectangle(frame, matchLoc,

nbr++;
}
else

}
