N2 - Aiming at the problem that the helicopter's adaptive landing zone cannot be selected adaptively under the changing of DEM data resolution, this paper proposes an adaptive search method for the helicopter's landing zone under the constraint of terrain index. The method introduces the resolution variation factor, and designs the indicators of landing zone selection: variance and roughness; According to the size requirements of helicopter landing zone in the wild, combined with the distribution map of the three indexes, an adaptive sliding window search strategy was designed, and the fault-tolerant percentage threshold was introduced to realize the adaptive method of landing zone search with terrain indexes constraint. The proposed method is experimentally validated by HLZs analysis on fixed scale and variable scale using DEM elevation data. The results show that the proposed method can effectively search helicopter landing zone under DEM horizontal resolution variation.
