| 摘 要： | 基于三维激光扫描技术进行表面积计算的原理为:获取的目标表面海量点云数据,采用一定的数学计算方法,便可求得场区的表面积。该方法弥补了传统方法计算物体表面积只能获取表面离散点坐标,对于因堆积物表面形状复杂而无法测量到的离散点,只能通过插值计算得到的缺陷;解决了随着计算范围增大或地面起伏变化工作量不断增大,计算误差会随着地面起伏的增大的问题。结合项目实例,本文提出了一种采用三维激光扫描技术进行废弃矿山修复治理区的三维信息采集和表面积核算方法,并对该方法表面积计算的技术原理、表面积计算的技术路线及项目实施过程中遇到的难题及解决方案问题进行了详细阐述,为后续相关项目实施提供了一定的参考依据。

| Abstract: | The principle of surface area calculation based on 3D laser scanning technology is:the surface area of the field can be obtained by using certain mathematical calculation method for the massive point cloud data of the target surface.This method makes up the defect that the traditional method can only obtain the coordinates of the discrete points on the surface of the object,and can only calculate the discrete points through interpolation because of the complex shape of the surface of the deposit;it solves the problem that the calculation error will increase with the increase of the calculation range or the change of the work volume from the ground fluctuation.Combined with the project example,this paper puts forward a method of 3D information collection and surface area calculation of mine remediation area by using 3D laser scanning technology.And it expounds the technical principle of surface area calculation,the technical route of surface area calculation,the problems encountered in the project implementation process and the solutions in detail,so as to provide some references for the subsequent implementation of related projects. |
