Abstract

The invention discloses a high-precision positioning system of a micro-scale model car. The high-precision positioning system comprises a traffic simulation sand table, a micro-scale model car, a video acquisition device, an image processing analysis unit and a communication unit. The system collects a real-time image of the micro-scaled model car on the traffic simulation sand table through the video acquisition device, transmits the image to the image processing analysis unit to process and obtains a real-time position and a car ID of the micro-scale model car, and then the data is mapped toa high-precision map coordinate system of the traffic simulation sand table, so that the real-time position of the micro-scale model car with the ID feature can be obtained. According to the system,the problems of difficulty in actual scene test and complex data collection in the research and application process in the fields of urban intelligent traffic, traffic safety, vehicle road cooperation, automatic driving and man-machine collaborative driving, traffic accident analysis and the like can be solved.

Description

technical field [0001] The invention belongs to the fields of urban intelligent transportation, simulated driving, traffic safety, vehicle-road coordination, automatic driving, human-machine cooperative driving, etc., and specifically relates to a method of monitoring moving miniature model vehicles on an indoor traffic simulation sand table through video analysis technology. System and method for high-precision positioning. Background technique [0002] With the development of technologies such as Internet of Vehicles, vehicle-road coordination, automatic driving, traffic safety, hybrid driving, and human-machine collaborative driving, the current research in the above fields mainly adopts three methods: one is to use actual vehicles in real scenarios. Data collection and algorithm testing, but this method has high experimental costs, long preparation time, few test scenarios, and high test safety constraints, and cannot achieve large-scale, high-frequency, and real-time ex...
