Since 2015, the authors have been finding ways to utilize 3D point cloud data and actively utilize it, and the accuracy of the shape recovery process depends on the photography in the field.
Therefore, it was decided to simplify the aircraft markings and to evaluate the error of the coordinate values. The results showed that the error of the coordinate value was small for the anti-aircraft markers, and the shape was recovered to the 3D point cloud data with high accuracy, but it was anomalous for the mixture of floating objects, which reinforced the importance of the aircraft markers.
