simogasp / example_matching_with_cuda.cpp
Created July 9, 2020 19:08
// these contains the descriptors from the two images
// so you need to convert the AliceVision data structure for descriptors into GpuMat
cv::cuda::GpuMat inputGPUDescriptors1;
cv::cuda::GpuMat inputGPUDescriptors2;
// match the features
// this creates a brute force matcher (it matches each feature against all the others in the other image (more efficient in GPU)
cv::Ptr<cv::cuda::DescriptorMatcher> matcher= cv::cuda::DescriptorMatcher::createBFMatcher();
// this contains for each descriptor a vector of size knn (in this case 2) with the best and second best match for the descriptor
