[0002] Unmanned aerial vehicle aerial survey technology is widely applied in land, urban and rural planning, water conservancy and other industries with its low cost, high efficiency and high precision. When aerial survey operation is carried out by using unmanned aerial vehicle, a large number of image control marks often need to be laid out. At present, common image control marks include "L", "ten", "X" and "T" shapes, The main methods of image control mark laying include: (1) laying image control paper at the position where image control needs to be laid out, and fixing it well, which has the shortcomings of being easily damaged by human and inconvenient to recover; (2) spraying paint on the road surface where image control needs to be laid out, and scattering lime on land or grassland, which has high requirements for the mold and precision of the mark. At present, common molds are cut iron plates, telescopic rod splicing molds and inflatable air bag molds, which cause the inconvenience of carrying cut iron plates, the telescopic rod splicing mold can only make "L", "ten" and "X" shaped image control marks, and cannot meet the existing aerial survey industry piercing point precision requirements, and the inflatable air bag mold needs to be inflated every time it is used, which is not convenient to use.
