| 摘 要： | 本文针对ADS40在1∶10000、1∶2000、1∶500地形图测绘工作中的问题进行了研究和探讨,重点针对ADS40应用中坐标系的定制及转换方法、大地水准面精化成果应用等进行了相关研究。实验证明,该设备在不同比例尺的摄影过程中获得的IMU/GPS数据精度相当,IMU/GPS解算数据与飞行比例尺无关;有地面基站和精密单点定位技术解算精度相当,适用于现行各种比例尺的成图需求。空三解算针对不同比例尺采用无野外控制点或少量野外控制点的方法,较大减轻了野外测量工作量;生产整体流程中,采用整航带作业模式,减少了图幅拼接、DOM生成等的工作量,较传统框幅式作业方法有较大的优势。

| Abstract: | Application of ADS40 digital photogrammetryon in different scales (1∶ 10 000, 1∶ 2 000, 1∶ 500) were studied and discussed. The research was focused on enactment of reference frame and conversion of reference frame, application of quasi-geoid refinement.The results showed that using ADS40, the precision of IMU/GPS data on different scale were the same and there was no correlation between IMU/GPS computing result and scales. Furthermore, the computing precision is same for plots where there is ground base stations and for GPS precise point positioning. This facility (ADS40) is suitable for photogrammetryon on all kinds of the scale. In aerotriangulation, plots without reference point or a few reference points were used according to differences among the scales, which saved a lot of field measurement. In the whole production process, using of zonary airscape reduced workload on picture jointing and DOM creating, which has much more advantage than the traditional frame airscape. |
