Hello,
I am using openCV for my first time, and I'm having some problems.
The matter is that I want to use the CUDA functionallity, but it gives me an error:
OpenCV Error: Gpu API call (NCV Assertion Failed: NcvStat=25, file=/home/alex/Downloads/opencv-3.0.0/modules/cudalegacy/src/cuda/NCVHaarObjectDetection.cu, line=2421) in NCVDebugOutputHandler, file /home/alex/Downloads/opencv-3.0.0/modules/cudaobjdetect/src/cascadeclassifier.cpp, line 156
terminate called after throwing an instance of 'cv::Exception'
what(): /home/alex/Downloads/opencv-3.0.0/modules/cudaobjdetect/src/cascadeclassifier.cpp:156: error: (-217) NCV Assertion Failed: NcvStat=25, file=/home/alex/Downloads/opencv-3.0.0/modules/cudalegacy/src/cuda/NCVHaarObjectDetection.cu, line=2421 in function NCVDebugOutputHandler
What I'm trying to do is only to measure the time that CUDA lasts to process my image, here is the code:
#include "opencv2/objdetect/objdetect.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/cudaobjdetect.hpp"
#include "opencv2/cudaimgproc.hpp"
#include "opencv2/cudawarping.hpp"
#include
#include
using namespace std;
using namespace cv;
int main(){
vector faces;
Mat image = imread("image.jpg");
Mat imageGray;
cuda::GpuMat imageGPU(image);
String s = "cuda.xml";
Ptr _faceCascade = cuda::CascadeClassifier::create("cuda.xml");
cuda::GpuMat objectBuffer;
clock_t t_ini, t_fin;
double secs;
t_ini = clock();
_faceCascade->detectMultiScale(imageGPU, objectBuffer);
t_fin = clock();
_faceCascade->convert(objectBuffer, faces);
secs = (double)(t_fin - t_ini) / CLOCKS_PER_SEC;
cout << secs * 1000 << "milliseconds" << endl;
for (int i = 0; i < int(faces.size()); i++){
cv::rectangle(image, faces[i], Scalar(255));
}
imshow("Result", image);
waitKey(0);
return 0;
}
I'm working with Eclipse and CUDA 7.5
Thanks!
