无人机摄影测量技术像控点布设方案研究——应用于水利水电工程
|
摘要
无人机低空摄影测量技术已经广泛应用于工程测量,像片控制点作为直接影响内业成图精度的关键,国内已经逐渐展开研究,但是目前并没有研究针对水利水电工程提出具体的像片控制点布设方案。文章在研究区域网布点法基本原则基础上,结合水利水电工程的实际情况,提出两种像片控制点布设方案,并利用固定翼无人机进行平原地区1∶1000比例尺测图实验,然后对平差后控制点和检查点的残差进行统计分析。结果表明,这两种像片控制点布设方案能够满足水利水电工程测量的要求。
The low-altitude aerial photogrammetry technology has been widely applied in engineering measurements. As the key directly affecting the accuracy of in-field mapping,the deployment of image control points has been gradually studied. However,there are currently no specific layout programs of image control points for water conservancy and hydropower projects. Based on the study of the principle of image control points layout program in regional network and the actual situation projects,two kinds of layout programs are proposed. Then two experiments are conducted in the plain area of water conservancy and hydropower project with 1 ∶ 1000 scale,using a fixed-wing UAV. Then the residuals of the control points and checkpoints after adjustment are statistically analyzed. The result shows that these two kinds of image control point layout programs proposed in the article can meet the requirements of water conservancy and hydropower engineering measurement.
