Accuracy comparison. (a) -direction accuracy comparison, (b) -direction accuracy comparison, (c) elevation accuracy comparison, and (d) relative accuracy comparison (where the horizontal axis represents the feature number and the vertical axis represents an error, the solid line represents the feature point coordinate error on point clouds and total station measurement data after calibration, and the dotted line represents the error before calibration).
