zero results

I would like to get the extrinsic calibration matric of two Livox horizon lidars, after several times attends, I just can get the wrong result from the repo. are there any mistakes I made in the process?
trial 1: lidar ( applied Livox viewer calibration ) + identity init_Matrix.txt
trial 2: clean lidar + init_Matrix.txt convert from livox viewer auto_calib
trial 3: clean lidar + identity init_Matrix.txt

I also try other scenarios( carpark + street) , but all the trials get the similar strange results.
