Abstract

The invention discloses a dual-use target image control point for UAV photogrammetry and radar scanning. The target image control point comprises a center block, wing plates and an image control cloth. The wing plates are detachably connected with the center block, and the image control cloth is fixedly connected under the wing plates. The four wing plates form a vertical cross. Two wing plates onthe same straight line are provided with reflective strips in the same color different from that of reflective strips on the other two wing plates on the other straight line. The image control clothon two sides of the wing plates is set in different colors, so that the dual-use target image control point can be used for photography shooting and the radar scanning, and the workload of control point arrangement and the processing amount of measurement data are reduced.

Description

technical field [0001] The invention relates to the technical field of ranging setting, in particular to a target image control point dual-purpose for unmanned aerial vehicle photogrammetry and radar scanning. Background technique [0002] In UAV field surveying and mapping, two different methods are often required to collect data. One is to use the camera mounted on the UAV to obtain an orthophoto image, and by identifying the image control points on the ground, the precise plane position can be obtained; the other is to use the laser radar mounted on the UAV to scan to obtain a point cloud Data, by identifying targets on the ground, accurate elevations can be obtained. However, in the prior art, image control points and targets need to be arranged separately for the two acquisition methods, and if the image control points and targets do not overlap, the amount of data processing will be large. Contents of the invention [0003] The purpose of the present invention is t...
