| Zusammenfassung: | The invention discloses a field ridge contour extraction method and system. Compared with the prior art, the method has the advantages that rasterization processing and low-dimensional mapping are adopted, multiple clustering operations are avoided, the data are mapped to the two-dimensional space for calculation, the calculation amount is reduced, and the calculation speed is greatly increased.
本发明公开了一种田坎轮廓提取方法及系统。与现有技术相比，本发明本申请采用栅格化处理及低维度映射，避免了多次聚类操作，且将数据映射到二维空间进行计算，减少了计算量，极大地提高了计算速度。 |
