激光雷达在水土保持监测中的应用

针对开发建设项目的水土保持监测,提出了一种新的渣场测量方案,即结合激光雷达技术和差分GPS技术,优势互补。该方案运用于实际,取得了很好的效果,实践证明它是一种更加科学高效的技术和方法,可应用于目前开发建设项目水土保持监测。（1）它在测量精度上比传统方法测量结果要精细许多,更真实、可信;（2）可详细反映渣场形态,轻松实现三维建模;（3）真正实现了非接触式测量,大大减少了外业工作量,降低了外业危险;（4）可对开挖边坡、崩岗、山体滑坡等许多形式的水土流失进行测量,使传统水土保持走上“精耕细作”之路。

Lidar Application to Soil and Water Conservation Monitoring

Aiming at soil and water conservation monitoring in development and construction projects, a new scheme that uses advantages of lidar and DGPS is presented for the application to reality. Some good effects of the scheme have been observed. It is proved that the scheme is a scientific and highly effective method, and thus can be widely used in development and construction projects at present. In addition, its measurement precision is much finer than traditional methods, and it is more real and more credible. The scheme can exquisitely reflect the change in shape of dregs field; easily realize the three dimensional modeling; truly realize the non-contact measurement; greatly reduce field workload and the risk. Moreover, the scheme is able to measure soil erosion of many forms, such as excavated slope, collapsed hill, and mountain landslide, and helps to promote the traditional soil and water conservation towards precision farming.
