Abstract

The embodiment of the invention provides a vehicle type identification method and device, and relates to the field of data processing, and the method comprises the steps: obtaining point data collected by a laser radar in a data collection scene; clustering the obtained point data to obtain point cloud cluster data used for describing vehicles in the data acquisition scene; carrying out feature extraction on point data in the point cloud cluster data to obtain a feature set of the point cloud cluster data, wherein the feature set comprises at least one of the following features: a geometric feature, a transverse contour feature, a longitudinal contour feature, an inertia tensor feature and a statistical feature of point data correlation; using the inertia tensor features for representing mass distribution features described by the point cloud cluster data when the vehicle rotates; and matching the feature set of the point cloud cluster data with the feature set of each preset vehicle type, and determining the vehicle type described by the point cloud cluster data based on a matching result. The scheme provided by the embodiment is applied to vehicle type identification, so that the vehicle type identification efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a vehicle type identification method and device. Background technique [0002] Various types of vehicles can be accommodated on the road. Specifically, the types of vehicles include motor vehicles and non-motor vehicles. More specifically, the types of motor vehicles include cars, buses, etc., and the types of non-motor vehicles include bicycles. type, electric vehicle type, etc. Various types of vehicles need to drive in the preset driving area of ​​the road, for example: motor vehicle type vehicles need to drive in the motor vehicle driving area of ​​the road, non-motor vehicle type vehicles need to drive in the non-motor vehicle driving area of ​​the road within the area. When vehicles that do not belong to the driving area appear in the driving area of ​​the road, it will have a certain impact on road traffic safety. For example: when there are non-motor vehicles d...
