无人机倾斜摄影在土方测量中的应用研究

Research on the Application of UAV Tilt Photography in Earthwork Survey

无人机倾斜摄影能有效解决传统土方测量外业受地形限制大、工作烦琐,内业计算复杂、精度低等问题。将无人机倾斜摄影技术应用于土方测量的实际案例中,并与传统土方测量在坐标、高程、土方量等获取的数值进行对比,结果表明:利用无人机倾斜摄影技术进行土方测量,坐标、高程、土方量的差值均满足规范要求,成果质量可靠。通过对无人机倾斜摄影土方计算的原理进行研究,介绍了数据外业采集与内业处理的过程,并对土方测量的精度进行统计。

UAV tilt photography can effectively solve the problems of traditional earthwork measurement,such as large terrain limitation,tedious work,complex calculation and low accuracy.The UAV oblique photography technology is applied to the actual case of earthwork measurement,and compared with the traditional earthwork measurement in the coordinates,elevation,earthwork and other values obtained.The results show that the use of UAV oblique photography technology for earthwork measurement,the difference between coordinates,elevation and earthwork meets the requirements of the specification,and the quality of the results is reliable.This study studies the principle of earthwork calculation of UAV tilt photography,introduces the process of data field collection and internal processing,and counts the accuracy of earthwork measurement.
