坡面侵蚀沟监测仪遵循地表糙率仪的基本工作原理,利用激光测距和扫描等非接触式测量技术,以非接触式射线替代接触式的测针,将侵蚀沟断面线密集地等分为大量的离散样点,将所有离散样点的距离量集合在一起形成数字化的侵蚀沟断面地形。测量仪的测距设备校验误差为±1.5 mm,采样测距点的标准水平间距约为5 mm。应用实践表明,与传统的卷尺法、地表糙率仪法等地表特征测量工具相比,该测量仪具有非接触式测量、精度高、自动量测及存储的特点。
Slope Erosion Groove Monitor follows the basic principle of the surface roughness meter and utilizes non-contact measurement techniques such as laser ranging and scanning to replace the contact stylus with non-contact rays and densely divide the erosion gully line For a large number of discrete samples, the distances of all the discrete samples are collected together to form a digital eroded trench profile. The measuring device has a calibration error of ± 1.5 mm for the distance measuring device and a standard horizontal distance of 5 mm for the sampling and distance measuring point. Practical application shows that compared with traditional measuring instruments such as tape measure and surface roughness meter, the measuring instrument has the characteristics of non-contact measurement, high precision, automatic measurement and storage.
