WebMar 11, 2024 · It is not uncommon for 20-30% of the matches to be incorrect. Fortunately, the findHomography method utilizes a robust estimation technique called Random Sample Consensus (RANSAC) which produces the right result even in the presence of large number of bad matches.Lines 50-60 in C++ and Lines 36-45 in Python accomplish this in code. WebOct 31, 2016 · First, follow the earlier solution to compute the homography matrix. After you have the homography matrix, you need to warp the image with respect to the Homography matrix. Lastly, merge the warped image. Here, I will share another idea that could be used to merge the warped images. football field goal kicking technique
