2017-06-07 01:56:07 -0500 | asked a question | Estimation of ball position (3d reconstruction) I have a white small ball in camera view. The ball is in front of camera but higher than camera (Yball > Ycam). View is compensated by undistort(). I try to calculate X and Y position of the ball relative to camera position. What I know: 1) Ball X coordinate is in center |

2017-01-05 06:32:08 -0500 | asked a question | Get 3d coordinates by 2d point on camview Hi!, I have calibrated camera (i have camera_matrix, distortion_coefficients, projection_matrix). My cam is pointed to a wall. When I choose a point on 2d image (camera view capture), I would like to get a point of wall in world coordinates, assuming that cam is coordinate origin and distance from cam to real point on wall is known. Could you please help me how to do it? Regards, |
