[codehardso]

Hi,I want to use your joint_calib function to calibrate lidar and camera, thanks for the great work! And I want to know how to get the Extrinsic Matrix in my Terminal.

Thanks in advance.

请问你解决了吗？我也想知道如何输出外参，我现在看见只有每张图一个不同的外参矩阵
Have you solved it yet? I also want to know how to output external parameters, I now see only a different external parameter matrix for each graph
