摘要
针对现代智能农业中存在的土壤墒情传感器布点的问题,提出了一种基于Delaunay三角剖分的传感器布点方法。该方法采用Delaunay三角剖分将区域三角网格化,考虑不同网格区域土壤的墒情和变异系数,对于变化剧烈的区域采用三角网格局部加密的方法,从而实现全方位的布点监测。使用MATLAB,对整个布点的过程进行了仿真,并通过实验验证了算法的可行性和可靠性。
To optimize the placement of soil moisture sensors in modern intelligent agriculture,an optimal placement based on Delaunay triangulation has been proposed.The area is divided into several triangular meshes by Delaunay triangulation and local refinement of triangular mesh is utilized for solving the local triangular region where soil moisture is found to vary drastically and coefficient of variation don＇t satisfy the condition,which implement omnidirectional monitoring.Based on MATLAB,the simulation is conducted for the entire process,and the feasibility and reliability of the algorithm is verified by experiment.
