Abstract

The invention discloses an image control point target system and a method for unmanned aerial vehicle measurement and airborne laser radar. The image control point target system comprises a target panel, laser radar transmitting targets, a center bolt hole and a center mark target. The laser radar transmitting targets are fixedly arranged at four corners of the target panel; the central bolt holeis fixedly formed in the central position of the target panel; and the central mark targets and the central bolt holes are fixedly connected and are uniformly and fixedly arranged on the target panel.The image control point target system is simple in structure, easy to manufacture and low in requirement for the operation environment, and basically meets the requirement for terrain operation. Theimage control point target method is easy to operate, the workload is reduced, the operation efficiency is improved, and the image control point target method can be used as an image control point forunmanned aerial vehicle photogrammetry and airborne laser radar photogrammetry at the same time and is dual-purpose.

Description

technical field [0001] The invention belongs to the technical field of surveying and mapping, and in particular relates to an image control point target system and method for unmanned aerial vehicle measurement and airborne laser radar. Background technique [0002] At present, the UAV aerial photography system is a useful supplement to the traditional aerial photogrammetry technology. It can operate in harsh environments and high-risk areas, especially in small and complex areas, and areas with complex landforms and meteorological conditions. It fully embodies the characteristics of UAV remote sensing, such as flexibility and wide application range. With the development in recent years, UAV photogrammetry technology has become an important technical means for resource and environment investigation, real-time monitoring of emergencies, disaster prediction and assessment, etc., and plays an important role in aerial photogrammetry. Airborne lidar is a new type of active obser...
