The invention discloses a farmland terrain profiling measurement method, which comprises the following steps that a laser scanner is erected beside a farmland, the height between laser emitted by the laser scanner and the ground is h base, and the laser rotates and scans in the horizontal direction parallel to the ground to form a horizontal laser datum plane; a navigation receiver is installed in the center of a frame of an elevation information obtaining trolley, the height of a trolley body is h1, laser receiving supports are installed on the positions, in front of and behind the navigation receiver, of the frame of the elevation information obtaining trolley respectively, laser receivers are installed at the upper ends of the laser receiving supports, and the height of the laser receiving supports is h2. Enabling the zero position of the laser receiver to be flush with the horizontal laser reference surface; the elevation information acquisition trolley traverses the whole farmland measurement area according to a navigation established route to acquire farmland elevation information and generate a farmland elevation three-dimensional topographic map; according to the invention, the elevation information of the whole farmland grid is measured at one time by traversing the farmland to be measured, the rapid and accurate acquisition of the farmland terrain is realized, and the measurement efficiency and accuracy are improved.
本发明公开了一种农田地形仿形测量方法,包括以下步骤:在农田边架设激光扫描仪,激光扫描仪发射出去的激光和地面间的高度为h基,激光平行于地面水平方向旋转扫描,形成水平激光基准面;在高程信息获取小车的车架中心安装导航接收器,小车车身高度为h1,导航接收器前后方的高程信息获取小车的车架上分别安装有激光接收支架,激光接收支架上端安装有激光接收器,激光接收支架的高度为h2,使激光接收器零位与水平激光基准面平齐;高程信息获取小车按照导航既定路线历遍整个农田测量区域,获得农田高程信息,生成农田高程三维地形图;本发明通过历遍待测农田,一次性测量整个农田网格的高程信息,实现农田地形的快速、准确获取,提高了测量效率和准确度。
