- W4385444711 abstract "Roadside-LiDAR sensing system can provide the full trajectories of all-type road users around the deployed traffic facility, which is a new-generation traffic data to assist traffic safety and operation applications. Background filtering is a critical step of roadside-LiDAR data processing that significantly affects processing quality and efficiency. Existing background filtering methods heavily rely on statistical or empirical approaches for model parameter determination, so they normally work well for some scenarios but cannot accommodate others due to different traffic characteristics. In this paper, a novel background filtering method is developed, whose model parameters can be automatically determined with the site’s traffic-related measurements. The new method is designed to work on a ranging image data structure derived from the spherical features of the LiDAR sensor. The performance evaluations are conducted at three signalized intersections equipped with 32-line LiDAR sensor roadside-LiDAR under 10 Hz operational frequency, which demonstrated that the developed method can guarantee a high background filtering accuracy with more underlying foreground points detected, meanwhile achieving a significantly higher processing efficiency in comparison with existing methods." @default.
