Vehicle trajectory holographic perception method based on laser range sensors
To achieve real-time holographic perception of vehicle trajectories on all sections of highways,this paper aims to explore a cost-effective and easily deployable method for holographic perception of vehicle trajectories.Initially,perception devices composed of laser range sensors,distributed along the roadside,are used to collect discrete trajectory profile information of vehicles in real time.Subsequently,by conditional matching,the information from adjacent detection profiles is matched and associated to obtain the sequence of trajectory points for each vehicle.Finally,cubic spline interpolation is used to reconstruct the complete trajectory of the vehicles.Verification shows that the reconstructed vehicle trajectories are fundamentally consistent with their actual trajectories,demonstrating the feasibility of this method in theory.
