运行roslaunch linkalibr ros_calib_init.launch后报错如下：

@huanghqc
Hi, Did you solve the problem?

huanghqc commented 2 years ago

@SubMishMar I didn't solve it, but I don't think this error will have much impact on the result, so I haven't considered this error

The process died on ros_calib_init_optimizer.cpp#L173 just after processing the last frame of the test data given in imu_lidar_calibration#data-collection-for-extrinsic-calibration.
