Single-lens unmanned aerial vehicle flight parameter setting method

Abstract

The invention discloses a single-lens unmanned aerial vehicle flight parameter setting method. The method comprises the steps of: determining the type of a construction site; acquiring a plurality ofpictures of a to-be-measured construction site; respectively recording dynamic flight parameters of the single-lens unmanned aerial vehicle at a first position and a second position in the heading direction and the lateral direction; calculating the course flight range, the lateral flight range and the flight height of the single-lens unmanned aerial vehicle; and establishing a point cloud model of the construction site according to the course flight range, the lateral flight range and the flight height set in the construction site. According to the method, the proper course flight range, theproper lateral flight range and the proper flight height are set according to different construction sites, the picture collection amount is reduced, the data collection time and the point cloud modelestablishing time are effectively shortened, the working efficiency is improved, and the established point cloud model meets the specification requirements and can be effectively applied to actual construction.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method for setting flight parameters of a single-lens unmanned aerial vehicle. Background technique [0002] The development of photogrammetry has entered the era of digital photogrammetry. With the development of drones in recent years and the launch of consumer-grade single-lens drones, airborne photogrammetry has been widely used in the engineering field, especially with BIM The combination of technology brings numerical advancement power to on-site construction and management. [0003] At present, UAV photogrammetry has been applied in the field of engineering for 3D reconstruction of sites, slope monitoring combined with BIM, and volume calculation of earthwork volume changes, etc., but most of the applications are aimed at discussing the method of model volume calculation and model accuracy , while little research has been done on how to improve the effi...

Problems solved by technology

Due to the limitation of battery performance when the drone is flying, the working time of the single-lens drone is mostly no more than 1 hour, and the flight route initially automatically designed by the drone software is much longer than the maximum flight distance of the drone , so during the data collection process, the staff often need to replace the battery several times; in addition, due to the fully automatic route calculation of the flight route design application on the smartphone, the amount of initially collected photos is too large, whether it is a valid photo in the later stage Both screening and point cloud model reconstruction take a lot of processing time
