Camera internal reference #151

zed_left_uurmi.ini： screenshot-20240712-173239 config_file.txt： screenshot-20240712-173307 I understand that they should be the same thing, but their values are completely different I have searched all ini files and found that none of them have the same camera matrix as the camera matrix in the config_file.txt. May I ask what their relationship is, which parameter is the camera internal parameter, and what is the other one? How to obtain it I am very confused and hope to receive your help. Thank you very much

Hi @xudh1991, the data in the .ini file will likely be different for your specific camera, so you should create a new one. You can use the ROS package camera_calibration to automatically generate all the necessary data. For more information, go to: https://wiki.ros.org/camera_calibration

Regarding the config_file.txt, I found that it worked well without any changes. After seeing your issue, I tried updating it with the new matrix generated by the camera_calibration package, but it didn't work. Therefore, I suggest leaving the config_file.txt as it is.

I hope this helps!
