轻小型无人机城市三维建模精度分析与评价

摘要

针对目前城市三维模型构建缺乏可量化的精度评价指标问题,提出城市三维模型精度分析评价的控制点布设方案.该布设方案在遵循低空航摄控制点布设规范的基础上,根据统计特性,布设控制点以及检查点.采用该控制点布设方案进行了试验.分析表明,该方式为三维模型构建精度评价提供了一套较为有效的解决方案.%According to the problem of lack of accuracy evaluation method for the urban 3D model,this paper presents a control point layout scheme.The layout scheme is based on the standard of the control point of low altitude aerial photography and statistical characteristics.Experimental results show that the control point layout provides a set of effective solutions for the accuracy evaluation of 3D model construction.
