Abstract: “In this paper, we evaluate the multi-scale PCA feature characteristics of point cloud and apply the feature in the underwater object recognition task. We analyses the raw point cloud from ModelNet database and compare the multi-scale feature among interested category. We also device the underwater experiment to evaluate the proposed algorithm. The result of experiment demonstrate the potential of multi-scale PCA feature in underwater object recognition task.”
