Camera Calibrator: points at the intersection of the frames

Hello, I have a problem with the Camera Calibrator app. My problem is that it introduces intersection points in places outside my correction panel, which makes my correction not correct. Is it possible to delete these points manually? And on the other hand, is it possible to manually place the points at the intersection of the frames?

Hi Pedrp,

Based on the information provided, it seems that you are encountering an issue with incorrect intersection points generated by the Camera Calibrator app. The Camera Calibrator app utilizes the ‘generateCheckerboardPoints’ function to generate ‘worldPoints’. ‘worldPoints’ is a matrix, which contains the corner coordinates ‘[x, y]’ for the squares on a checkerboard. The size of the matrix is ‘M-by-2’, where ‘M’ represents the number of corners. It is worth noting that the point ‘[0, 0]’ corresponds to the lower-right corner of the top-left square on the board.

By modifying the coordinates of the points in the 'worldPoints' matrix, you can add or delete points as needed to align with your specific requirements.

For more detailed information on how to generate checkerboard corner locations using the ‘generateCheckerboardPoints’ function, I recommend referring to the following documentation: Generate checkerboard corner locations - MATLAB generateCheckerboardPoints - MathWorks India

I hope this information helps you in resolving the issue.
