Abstract: Aiming at the problems of low accuracy and low automation of pole-like objects classification in vehicle laser scanning data, a classification method based on BP neural network is proposed. Firstly, according to the point cloud characteristics of the pole-like object, ten eigenvalues are selected to obtain the feature vectors of the pole-like object clustering unit, and then eigenmatrix is constructed. Secondly, the BP neural network model is trained by using the sample set and the classification model is saved. Finally, the BP neural network classification model is used to classify the pole-like object in the test area. The experiment showed that the classification accuracy of the method for pole-like objects could reach 95.34%, which also verifies the effectiveness of the method.

Key words: pole-like objects, neural network, automatic classification, eigenvalues, classification model
