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