【摘要】：随着科技在发展,测绘技术手段也在不断创新。eBee无人机技术作为一项测绘新技术,它不仅轻便,操作简单,而且能够精确、高效的作业,获取的遥感影像分辨率可高达5-20cm,突破了传统卫星遥感数据分辨率不高、获取周期长、价格昂贵的局限,受到测绘领域越来越多人的青睐。三维激光扫描技术同样是作测绘领域新发展的测绘新技术,它打破了传统测量中单点采集数据的方式,发展为采用面数据方式采集。与传统测量模式相比较,三维激光扫描技术可以全天候作业、实时采集、快速获取高精度点云数据及获取巨大的数据量,而且对三维模型可以进行一些数据量算分析。360全景也称为三维全景或环视全景。它是一种基于图像的虚拟现实技术,由于其较好的人机交互的特性,已经广泛应用与各个行业。本研究综合应用eBee无人机系统、Faro地面三维激光扫描仪、Qpad移动GIS数据采集器,360全景4种测绘新技术运用到矿区土地复垦管理的三个方面:矿区土地损毁调查,矿区土地复垦监测,矿区土地复垦效果展示。在研究和确定矿区土地损毁类型的基础上,获取高清无人机影像后进行解译、验证和统计分析,分别选取毁损区域的对正、负进行扫描、建模与三维量算,较好地实现了矿区毁损情况快速、准确调查。最终实现针对矿区土地损毁从二维定性分析到三维定量分析,为矿山公园的开发与保护提供决策依据。
[Abstract]:With the development of science and technology, surveying and mapping technology means is also constantly innovating. EBee UAV technology as a new surveying and mapping technology, it is not only portable, simple operation, but also accurate and efficient operation. The resolution of remote sensing image obtained can be as high as 5-20 cm, which breaks through the limitation of low resolution, long acquisition period and expensive price of traditional satellite remote sensing data, and has been favored by more and more people in the field of surveying and mapping. Three-dimensional laser scanning technology is also a new technology of surveying and mapping. It breaks the traditional method of single point data acquisition in surveying, and develops into the use of surface data acquisition. Compared with the traditional measurement mode, 3D laser scanning technology can be used to obtain high accuracy point cloud data and large amount of data. And we can do some data analysis for 3D model. 360 panorama is also called three-dimensional panorama or circle panorama. It is a kind of virtual reality technology based on image. Because of its good human-computer interaction, it has been widely used in various industries. In this study, four new surveying and mapping techniques of eBee UAV system, Qpad, moving GIS data collector, are comprehensively applied to three aspects of land reclamation management in mining area: land damage investigation in mining area, land reclamation monitoring in mining area. The effect of land reclamation in mining area is displayed. On the basis of studying and determining the type of land damage in mining area, the images of high-definition UAV are obtained and interpreted, verified and statistically analyzed, and the positive and negative scanning, modeling and three-dimensional calculation of the damaged area are selected respectively. The damage situation of mining area is investigated quickly and accurately. Finally, the land damage in mining area is realized from two dimensional qualitative analysis to three dimensional quantitative analysis, which provides the decision basis for the development and protection of mine park.
