摘要
针对传统土方量测量方法存在的测量周期长、误差大、对测量环境依赖程度高等缺点,提出基于无人机倾斜摄影技术的土方量测量方法.采用无人机倾斜摄影方式建立实景三维模型,通过采集高程特征点进行土方量精确计算,并对比分析传统测量方法与无人机倾斜摄影技术的优缺点.结果表明:基于无人机倾斜摄影技术获取到的高程值与外业实测高程值差值较小,成果精度良好,满足土方量测量要求,能够为后期土地平整规划相关工作提供新的有效途径.
Abstract
In response to the shortcomings of traditional earthwork volume measurement methods,such as long measurement cycles,large errors,and high dependence on the measurement environment,a new approach based on drone oblique photography technology is proposed.This method utilizes drone oblique photography to establish a three-dimensional model of the actual scene.By collecting elevation feature points,precise calculations of earthwork volume can be performed.A comparative analysis is also conducted to assess the advantages and disadvantages of traditional measurement methods and drone oblique photography technology.The results indicate that the earthwork volume measurement method based on drone oblique photography technology exhibits high measurement accuracy and efficiency,meets the requirements of earthwork volume measurement and can provide a new and effective approach for subsequent land leveling and planning efforts.
