Research on UAV Path Planning Based on Terrain Data Interpolation Technology

文中采用多种插值方法模拟真实的地形环境,将传统的PSO算法改进为适用于山区等复杂区域的SPSO算法并求解航迹.与未改进的PSO算法相比,航迹长度变化率减少了85.68%,计算时间减少了59.65%,规划出的航迹更符合实际需求.

A variety of interpolation methods were used to simulate the real terrain environment,and the traditional PSO algorithm was improved to SPSO algorithm suitable for complex areas such as mountainous areas and solve the track.The results show that,compared with the improved PSO algorithm,the change rate of track length is reduced by 85.68%,and the calculation time is reduced by 59.65%,so the planned track is more in line with the actual needs.The research results have high practical significance and application value for solving the problems of inaccurate terrain simulation,low track safety and feasibility in the previous research on UAV track planning.
