摘　　要：随着现代无人机技术的迅猛发展,无人机摄影测量机载设备的提升和普及,结合计算机对影响资料的后期数据的快速发展,无人机在摄影测量行业的使用也越来越广泛。在利用无人机低空飞行摄影测量地形时,无人机搭载摄影设备对地形进行航测,具备良好的机动性,易操作,在一定程度上节约了人员和物力成本,无人机航测技术的精度与摄影机载设备的精度有关,但是同样条件下整个操作实施过程的环节也影响了最后的测量精度,在同等测量区域的环境条件下,不同的数目的像控点选择和位置布设,不仅影响户外工作效率,在一定程度上也影响最后的整体测量精度,因此,针对相同的测量区域,选择不同的像控点布设的实施方案,对像控点的测量精度进行最后的评估测算,保证兼顾工作效率和测量精度的前提下,通过无人机航测不同像控点布设方案对空三测量进行精度分析,总结出无人机航测像控点布设与空三测量的关系,在保证精度要求的前提下提高资源的利用效率。With the rapid development of modern UAV technology,the promotion and popularization of UAV photogrammetric airborne equipment,combined with the rapid development of computer to the later data affecting the data,UAV is more and more widely used in the photogrammetric industry.When using UAV low altitude flight photography to survey terrain,UAV carries photography equipment to conduct aerial survey of terrain,although it has good mobility,easy operation and saves personnel and material costs to a certain extent,the accuracy of UAV aerial survey technology is related to the accuracy of photography airborne equipment.However,under the same conditions,the links of the whole operation implementation process also affect the final measurement accuracy.Under the environmental conditions of the same measurement area,the selection and location layout of different numbers of image control points not only affect the outdoor work efficiency,but also affect the final measurement accuracy of the whole to a certain extent.Therefore,aimed at the same measurement area,different implementation schemes for the layout of image control points were selected,and finally the measurement accuracy of image control points were evaluated and calculated.On the premise of taking into account the work efficiency and measurement accuracy,the air-3 measurement accuracy was analyzed through different layout schemes of UAV aerial survey image control points,and the relationship between UAV aerial survey image control point layout and air-3 measurement was summarized.It improves the utilization efficiency of resources on the premise of ensuring the accuracy requirements.
