摘　　要：针对无人直升机自主着舰中准确识别着舰标志的需要,提出了一种基于Hu矩的无人直升机着舰标志分块匹配识别方法。分析了无人直升机自主着舰中的着舰标志识别问题,给出了基于分块匹配的着舰标志识别处理流程;在此基础上,实现了对视觉图像在不同场景下的预处理;最后,在不同场景下对所提方法的有效性与可行性进行了实验验证,结果表明,应用该方法能够较好地实现对着舰标志的识别,具有一定的军事应用价值。Aiming at the need of accurate identification of the ship's mark in the autonomous landing of an unmanned helicopter,a Hutt-based approach for block matching and identification of an unmanned helicopter landing sign is proposed. First of all, this method analyzes the problem of identification of landing signs in the autonomous landing of unmanned helicopters, and presents the processing flow for identification of landing signs based on block matching. Thus, the advance processing of visual images under different scenarios is realized. Finally, the effectiveness and feasibility of the method proposed in this paper are verified experimentally under different scenarios. The results show that this method can be used to realize the recognition of the landing sign and has certain significance in military application value.
