Research on route planning of aerial photography of UAV in highway greening monitoring

UAV (unmanned aerial vehicle) image technology has the advantages of wide shooting range, large inventory space, strong timeliness and so on, when it is used in highway detection. In addition to the basic parameters such as image quality, resolution and overlap, the safety of flight routes should also be taken into account in aerial photography of highways in operation. Optimal route planning is the premise and guarantee for the application and promotion of UAV in the field of highways. By adopting appropriate shooting form, flight height and angle, the actual road condition information can be collected to ensure high accuracy of data information. This provides great convenience for the actual situation of highway green belt, the confirmation of the location of plant growth and other aspects. It plays an important role in promoting the maintenance efficiency and level of highway green belt. This paper quantitatively analyzes and studies the optimal aerial route planning for unmanned vehicles in highway field.
