Multiple point clouds before and after boresight calibration in experiment 1. (a) Original point cloud; ((b), (d), and (f)) point clouds of cross-section 1, cross-section 2, and cross-section 3 before boresight calibration; ((c), (e), and (g)) point cloud of cross-section 1, cross-section 2, and cross-section 3 after boresight calibration. Points derived from different strips have different colors.
