摘要
像控点布设精度是直接影响无人机倾斜摄影测量结果的重要因素之一,为此提出无人机倾斜摄影测量像控点布设精度控制方法。利用无人机搭载CCD相机采集测量区域图像后,首先对其正向和切向畸变进行校正;然后以校正后的图像为基础,利用Inpho软件对测量像控点自动布设;再自动匹配刺点范围,Inpho软件自动标注无人机倾斜摄影像控点,实现无人机倾斜摄影测量像控点布设精度控制。实验结果表明:该方法可有效校正无人机倾斜摄影图像正向和切向畸变,有效控制测量像控点密度,且像控点布设精度较高。
The accuracy of image control points is one of the important factors that directly affect the results of unmanned aerial vehicle tilt photogrammetry.Therefore,a method for controlling the accuracy of image control points in unmanned aerial vehicle tilt photogrammetry is studied.This method uses a drone equipped with a CCD camera to collect images of the measurement area,and then corrects their forward and tangential distortions.Based on the corrected drone tilt photography image,the measurement control points are automatically arranged using Inpho software,and after automatically matching the prick range,the Inpho software automatically marks the drone tilt photography control points,achieving accuracy control of the drone tilt photography measurement control points.The experimental results show that the method can effectively correct the forward and tangential distortion of unmanned aerial vehicle tilt photography images,and can effectively control the density of measurement control points,and the accuracy of controlling unmanned aerial vehicle tilt photography measurement control points is high.
