基于单元格扫描和GPS轨迹插值的土地深松合格率获取方法
摘要：
基于单元格扫描和GPS轨迹插值的土地深松合格率获取方法，本发明涉及土地深松合格率获取方法。本发明的目的是为了解决现有方法计算土地深松合格率精度低，且存在作弊的问题。过程为：步骤一：数据采集：通过安装在农机设备上的GPS定位装置和深松传感器每隔固定时间采集农机经纬度坐标和深松作业深度；步骤二：坐标转换：将采集的农机经纬度坐标按照高斯投影变换转换为平面直角坐标系下的XY坐标；步骤三：分段插值；步骤四：构建外切矩形；步骤五：扫描，获取土地深松合格率M÷N×100％。本发明用于土地深松合格率领域。
摘要（英）：

The present invention provides a land deep scarification qualified rate obtaining method based on table cell scanning and GPS track interpolation, and relates to the land deep scarification qualified rate obtaining method. The objective of the invention is to solve the problems that the land deep scarification qualified rate is low in precision and is cogged through adoption of the current method. The method comprises: the step 1: data collection: collecting farm machinery longitude and latitude coordinates and deep scarification work depth at regular intervals through a GPS location device and a deep scarification sensor installed on an agricultural machinery; the step 2: coordinate conversion: converting the collected farm machinery longitude and latitude coordinates to XY coordinates in a rectangular plane coordinate system according to the Gauss projection transformation; the step 3: segment interpolation; the step 4: construction of an enclosing rectangle; and the step 5: scanning, and obtaining of the land deep scarification qualified rate of (M/N)*100%. The land deep scarification qualified rate obtaining method based on the table cell scanning and GPS track interpolation is applied to the land deep scarification qualified rate field.
