|
inRansacReprojThreshold | Integer | 0 -  |
Maximum reprojection error in the RANSAC algorithm to consider a point as an inlier. Applies only to RANSAC. |
|
inMaxIterations | Integer | 1 - |
The maximum number of robust method iterations. |
|
inConfidence | Double | Confidence level, between 0 and 1, for the estimated transformation. Anything between 0.95 and 0.99 is usually good enough. Values too close to 1 can slow down the estimation significantly. Values lower than 0.8-0.9 can result in an incorrectly estimated transformation. | |
|
inRefineIterations | Integer | 1 - |
Maximum number of iterations of refining algorithm (Levenberg-Marquardt). Passing 0 will disable refining, so the output matrix will be output of robust method. |
