基于改进多密度自适应DBSCAN的航迹起始方法
Track Initiation Method Based on Improved Multi-density Adaptive DBSCAN
摘要
Abstract
In the vehicle-mounted millimeter-wave radar scenarios,the traditional track initiation methods have problems such as low track initiation rate,a large number of false track initiations and track clustering.To solve above problems,an adaptive densi-ty-based spatial clustering of applications with noise(DBSCAN)parameter algorithm is introduced and improved in this paper,and a track initiation method based on improved multi-density adaptive DBSCAN is proposed.Firstly,the pre-processing technology,obtained by combining Hough transform and DBSCAN algorithm innovatively,can suppress the false track initiation from road edge clutters.Secondly,the pre-processed data is divided into different levels according to speed information,and DBSCAN parameters are adaptively generated by the median-based k-nearest neighbor method and mathematical expectation method,so as to improve the clustering effect of multi-density extended targets.Finally,an m/n logic is used to complete the track initiation.The simulation results show that the proposed method still has a track initiation rate of 85%when the target scalability is 0.3.The analysis of measured data shows that the method can keep the number of false track initiation below 2 and the track initiation rate above 97%in various road scenarios.关键词
