The use of CCD imaging element system and dynamic scanning-based detection system is affected by noise,resulting in incomplete contour detection.To solve this problem,the design of building contour target detection system based on UAV remote sensing image is proposed.According to the overall architecture of the system,it can be determined that the system is divided into a data acquisition module and a processing module.Select TLC2543A/D conversion chip to make the control word input continuously from the data input terminal.Use a semiconductor laser sensor to measure position information and image on an avalanche photodiode.Adopt MCS-51 one-chip computer internal data memory,transfer the normal operation procedure to the high-level,so that CPU reads the procedure.Select the 371-4615 model CPU board to coordinate and control the whole machine.Design the contour target detection process,use laser triangulation measurement method to calculate the distance of the contour target of the building to be measured,to avoid the influence of detection background noise.Extract building patches and locate corner points to complete building contour target detection.It can be seen from the experimental results that the system will not be affected by noise,can determine the contours and corners of buildings,and has certain reference significance for the target recognition of building contours.
