2013-03-09 01:39:17 -0600 | asked a question | Some trouble with Perspective Transform Hello, i use PerspectiveTransform and as a result have matrix of transformation. I need transform coordinates of ONE point using this matrix, i read that i can use coficient of matrix for calculate it, and matrix buil like this x'i = (Ax + By + C)/(ax y'i = (Dx + Ey + F)/(ax But when i use this formula it don`t work corectly every time I think that the transformation matrix in OpenCV has a different structure, or I made a mistake somewhere. Perhaps there is other variant coordinate transformation one point? And Sorry for my english) |
