An intelligent traffic physics simulation platform and a positioning method for the intelligent traffic physics simulation platform

Abstract

An intelligent car and a positioning method for an intelligent transportation physical simulation platform. The present invention is different from the radio frequency identification method in the application of electronic license plates. When realizing the positioning and navigation of the intelligent car, the card reader is placed in the car, and the passive electronic The tags are laid on the road, and each passive electronic tag corresponds to a coordinate in the global coordinate system. When the smart car passes over the passive electronic tag, the card reader recognizes the UID of the passive electronic tag and determines the UID of the passive electronic tag. The corresponding pose information is used to correct the position of the micro inertial navigation system. The simulation platform can be used for experimental research and simulation display of intelligent vehicle collaboration in a vehicle-vehicle-road network environment. This platform uses the embedded system carried by the smart car to directly control the car after processing the positioning information of the car, which saves communication time.

Description

Technical field [0001] The invention relates to an intelligent car and a positioning method for an intelligent traffic physical simulation platform, belonging to the field of traffic simulation simulation methods. Background technique [0002] In order to alleviate the pressure caused by the increasing traffic congestion on the urban road network, the concept of intelligent transportation in the vehicle-vehicle network environment has received extensive attention. It combines advanced communication network methods, sensor methods, computer methods and control methods. Such as organically integrated traffic management methods, including vehicle-vehicle collaboration, vehicle-road collaboration and other aspects. Because there are safety risks in directly applying new intelligent transportation methods to actual traffic, an intelligent transportation simulation platform based on road sand tables and smart cars is of great significance. The present invention designs a method of sim...

AI Technical Summary

Problems solved by technology

The GPS positioning method has a good effect in the outdoor environment, but it cannot be applied to the indoor environment due to the decrease in accuracy due to occlusion and other reasons. As an indoor positioning method, the wireless sensor network positioning method has attracted more and more attention from developers. The sensor network positioning method is still unable to achieve accurate indoor positioning

At present, the only method that can achieve accurate indoor positioning is the video positioning method. Since the road sand table is a double-layer structure, the video positioning method cannot solve the problem of occlusion between the upper and lower roads, and cannot be applied to this platform.
