how do calibration

[wataincdx]

hi, "coefficients k1, k2, k3 and k4 are given in the calibration files",how can you get k1, k2, k3 and k4 by calibration ?

[rvarun7777]

This is obtained by an internal tool where the cameras are calibrated in a factory setting for the production use cases. The calibration tool can not be provided. For different projection model calibrations, you can check an open-source toolbox kalibr

Can the calibration data be provided? If we get the checkerboard images, we can do the calibration ourselves in the model that we require. I require the OpenCV model of the fisheye calibration but the model used by the authors cannot be converted as per #58
