摘要
传统测绘技术与方法在复杂河道工程测绘中难以获取有效结果,鉴于此,论文在复杂河道测区条件下对比分析了无人机LiDAR和倾斜摄影测量技术的实际效果。通过高程误差与测量结果分析明确了两种工程测绘方法的优劣势,结合复杂工程的测绘要求,对两种方案进行了深度融合,借助选择迭代法有效降低了匹配粗差,满足了技术融合要求。采用无人机LiDAR和倾斜摄影融合测量技术,能够获取清晰的边界信息,图像内容更加丰富,处理时间更短,更利于人工判读与应用,满足了复杂河道工程测绘的工作要求。
Since it’s difficult for traditional surveying and mapping techniques to obtain effective results in complex river mapping,this paper compares and analyzes the practical effects of UAV LiDAR and tilt photogrammetry.With the analysis of elevation error and measurement results,the advantages and disadvantages of these two methods are clarified.The two methods are deeply integrated,and the matching gross error is effectively reduced by the selection iteration method,which meets the requirements of technology integration.And with the technique fusion of UAV LiDAR and tilt photogrammetry,clear boundary information can be obtained,the image content is richer,the processing time is shorter,and it is more conducive to manual interpretation and application,which meets the work requirements ofcomplex riverengineering surveying and mapping.
