2016-08-09 04:00:03 -0600 | commented question | Wrong measure on Zaxis on Translation Matrix of SolvePnP I think i have found the problem, when i run the calibration program it uses a 320x240 image when the camera is in fact 640x480. Thanks for the help! |
2016-08-09 03:53:30 -0600 | commented question | Wrong measure on Zaxis on Translation Matrix of SolvePnP Yes, i am working in mm and the square is 50x50mm. I am subtracting so i can get the contour position relatively to the center of the camera. My image is 640x480. I am pretty sure the camera matrix is correct. I used a camera calibrator to find the matrix. Also i try already with other camera and the same error occurred. Thanks for the help |

2016-08-05 11:45:37 -0600 | asked a question | Wrong measure on Zaxis on Translation Matrix of SolvePnP Hi, I am trying to get both rotation and translation matrix of a red square with webcam using SolvePnP. All the values are correct with my measures (with +-1mm of error) except the translation value of Z axis that gives me exacly half of the suppose value. EDIT: This is the code that give me the pose relatively to the center of the camera Result: Z distance in the translation axis is 158mm when it should be 320mm, the rest of values are correct The green circle is the center of the image |
