Vehicle behavior monitoring system based on radar and video group, and realization method thereof

Abstract

The invention relates to a vehicle behavior monitoring system based on radar and video group, and a realization method thereof. The system comprises multiple sets of monitoring terminal equipment, multiple sets of data communication equipment, data storage equipment, a background data processing server, a vehicle driving state display module and the like; the monitoring terminal equipment is composed of a millimeter wave radar, a high-definition camera, a front-end data processing unit module and a power control module. Compared with the prior art, the system disclosed by the invention realizes the advantage complementation of the millimeter wave radar data and the high-definition video image data on traffic data acquisition by deeply fusing the millimeter wave radar data and the high-definition video image data, so that the detected data type is more comprehensive, and the accuracy, reliability and robustness are further improved by steps, thereby being beneficial to providing technical support for the aspects of traffic control, safety early warning and the like.

Description

technical field [0001] The invention belongs to the technical field of road traffic data collection, and in particular relates to a vehicle behavior monitoring system based on radar and video groups and an implementation method thereof. Background technique [0002] At present, in the field of road traffic data collection technology, road traffic data collection methods mainly include video data collection methods and radar data collection methods. The advantage of using video data collection is that it has a visual effect and can identify the appearance attribute information of vehicles. However, it is greatly affected by the environment (weather, light), and the accuracy and reliability of the vehicle's spatial position and motion information detection are poor. [0003] Advantages and disadvantages of radar data acquisition: It is not affected by environmental conditions such as weather and light, and can detect the spatial movement and position information of vehicles in...

Problems solved by technology

However, it is greatly affected by the environment (weather, light), and the accuracy and reliability of vehicle spatial position and motion information detection are poor.

[0003] Advantages and disadvantages of radar data collection: It is not affected by environmental conditions such as weather and light, and can detect the spatial movement and position information of vehicles in real time. The detection accuracy is accurate and reliable, but because it does not have visualization effects, it cannot capture the appearance attribute information of vehicles

[0004] The above methods generally have defects such as low reliability, strong dependence on the environment, poor anti-interference ability, small coverage, unable to capture the behavior process in a large area, and inconvenient maintenance. The process characteristic information of continuous driving in a large range (usually a long road section with complex road conditions and prone to traffic accidents) has become a prerequisite for implementing in-depth management measures, and single-point or single-section data can no longer be used. To meet the current continuous development of basic research and application requirements, therefore, there is an urgent need for a new road traffic data collection method to meet the needs of the continuous development of road traffic control technology and the deepening of road traffic safety research in the new era
