Automatic monitoring system of vehicle with high-speed movement

Abstract

The invention discloses an automatic monitoring system of a vehicle with high-speed movement, and relates to a vehicle monitoring system. According to the automatic monitoring system of the vehicle, basic data is acquired in a synchronous manner by employing a laser sensor and a radar speed detector, the data is transmitted to a data processor, a mathematical model is established, an algorithm is designed, appearance characteristics of the vehicle are described by employing the data processor, the position of a lane at which the vehicle is located is determined, and speed feedback and data statistics of the vehicle are performed. According to the automatic monitoring system of the vehicle with high-speed movement, the mathematical model is established and the algorithm is designed by employing the data synchronously obtained by the laser sensor and the radar speed detector to restore the appearance of the vehicle, and the lane at which the moving vehicle is located and speed information can be fed back; and by employing matched hardware facilities, the road condition of the highway can be truly restored, the operation condition of the vehicle can be monitored, and the geometric characteristic and the corresponding speed of each vehicle in movement can be extracted.

Description

technical field [0001] The invention relates to a vehicle monitoring system, in particular to an automatic monitoring system for a high-speed moving vehicle. Background technique [0002] Since the reform and opening up, my country's expressway construction has developed by leaps and bounds. By the end of 2015, the total mileage of my country's expressway has reached 120,000 kilometers, which plays an increasingly important role in my country's economic development. However, on expressways or ordinary roads, the monitoring system for high-speed vehicles is extremely lacking. On most highways, "radar speedometers" are only installed to feed back and monitor the speed of high-speed vehicles, but other information about the vehicle, such as the geometric characteristics of the vehicle, cannot be known. [0003] At present, there are mainly two types of methods for extracting geometric feature parameters of vehicles: one is to extract geometric parameters of vehicles based on ...

Problems solved by technology

The visual and technical effects of the former are indeed very good, but the requirements of the external environment are relatively harsh, such as rainy and foggy weather, video technology can hardly play a long-distance role, and video technology also requires hardware facilities with a large amount of storage and powerful processing device; while the latter has low requirements on hardware facilities and is almost not affected by weather conditions, but only two of the three parameters of length, width and height can be obtained.
