WebJun 9, 2024 · For all RANSACs we first determined the optimal inlier threshold by the grid search, whereas the number of iterations ( max_iter ) was set to a reasonable 100k. Then, after fixing this optimal threshold, we vary the number of iterations from 10 to 10M. This gives us an accuracy-time curve.

"WebJan 8, 2013 · The distance ratio between the two nearest matches of a considered keypoint is computed and it is a good match when this value is below a threshold. Indeed, this ratio allows helping to discriminate between ambiguous matches (distance ratio between the two nearest neighbors is close to one) and well discriminated matches. " - Orb threshold
