Question: I want to try out this tutorial and therefore used the code from here in order to calibrate my camera. I use this image: The only thing I adapted was chessboard_size = (14,9) so that it matches the corners ...

Question: I calibrated a camera according to: which resulted in: I calculated the Rotation matrix according to: and created an Rt matrix resulting in: Now when I try to get the position of a realworld coordinate [0, 0.4495, 0] in ...

Question: I use this reference https://automaticaddison.com/how-to-perform-pose-estimation-using-an-aruco-marker/ to estimate pose of a marker. When I obtain cam matrix and distortion matrix I used the full camera resolution. However, when I change the resolution (image size) before pose estimation, I am getting ...

Question: I’m trying to find distortion coeffitients using Charuco Board from the Aruco OpenCV library. I’m using Qt and OpenCV libraries compiled for Qt. First I’ve needed to do is to create the Charuco Board. I’ve done it using this: ...

Question: I saw the answers here: How can I get pixel size in millimetres using camera calibration with checkerboard images in Matlab? but it wasn’t answered. I have a fixed camera and an object at a certain x distance from ...

Question: I try to create Structured-light 3D scanner. Camera calibration Camera calibration is copy of OpenCV official tutorial. As resutlt I have camera intrinsic parameters(camera matrix). Projector calibration Projector calibration maybe is not correct but process was: Projector show chessboard ...

Question: I have a setup with multiple cameras that all point towards the same scene. All cameras are calibrated to the same world coordinate system (i.e.: I know the location of all the cameras with respect to the origin of ...
