Hello, I want to detect the grid in a image.=20 Given a image, I detected edges and fitted lines, then got error when using sdet_grid_finder::computer_homography().=20 " failed to find dominant groups with at least 60 deg orientation". Does the function computer_homography() requires all lines are on grid? In my case the input image with complex background, I mean, there is chessboard in the image, but there are also some backgrounds in this image.=20 Anyone has experience using this class?=20 Thanks. |
