在无人艇避碰规划过程中,为准确识别障碍干扰意图,提出一种结合主成分分析(Principal Component Analysis,PCA)和支持向量机(Support Vector Machine,SVM)的分类算法.首先,利用PCA对船舶模型运动的高维运动特征数据集进行降维,获取特征集的主成分;再通过SVM对经过处理得到的低维主成分进行分类处理,以识别障碍对无人艇的干扰意图类型为主动干扰还是非主动干扰;最后,根据障碍的不同干扰类型,采用不同算法进行避碰、脱逃,通过这种差异化的处理,提升无人艇运动的安全性.仿真结果证明了该算法的有效性.

In order to accurately identify the obstacles interference intention in the process of collision avoidance planning for unmanned surface vehicle (USV), the classification algorithm based on principal component analysis (PCA) and support vector machine (SVM) was proposed. Firstly, PCA was used to reduce the dimension of the highdimensional motion feature data set of ship model motion to obtain the principal components of the feature set. Then, SVM was used to classify the low dimensional principal components, so as to identify whether the interference intention type of obstacles to the UAV is active interference or non active interference. Finally, according to the different interference types of obstacles, different algorithms were used to avoid collision and escape. Through this differential processing, the safety of the USV was improved. The simulation results verify the effectiveness of the algorithm.
