Problems solved by technology

However, the controllability of these participants is low, and there are many uncertain factors in their movement, and it is more obvious at the intersection of urban roads
In addition, once an accident occurs at a crossroad, it will cause serious traffic congestion and bring a lot of traffic pressure, which is especially serious in cities with high population density

Abstract

The embodiment of the invention provides a traffic detection system, which comprises: a first acquisition part for obtaining a monitoring video of a road; a second acquisition part for transmitting a radar signal to the preset area of the road and acquiring a radar reflection signal; a third acquisition part arranged on a vehicle and used for obtaining a video shot from the view angle of the vehicle; a first target detection device used for obtaining a first detection result of a target object according to the video shot from the view angle of the vehicle; and a second target detection device used for obtaining the second detection result of the target object according to the monitoring video of the road, obtaining the third detection result of the target object according to the radar reflection signal, and integrating the second detection result, the third detection result and the first detection result from the first target detection device to obtain the fourth detection result of the target object.

Description

technical field [0001] This application relates to the field of information technology. Background technique [0002] With the development of urban traffic, the traffic situation is becoming more and more complex. Compared with the relatively simple road conditions of expressways, there are many participants in urban road traffic, such as cars, bicycles, trucks, buses, pedestrians, etc. However, the controllability of these participants is low, and there are many uncertain factors in their movement, and it is more obvious at the intersection of urban roads. In addition, once an accident occurs at an intersection, it will cause serious traffic congestion and bring great traffic pressure, which is especially serious in cities with high population density. Therefore, how to improve travel efficiency and reduce traffic pressure is an urgent problem to be solved in urban traffic management. [0003] In recent years, intelligent transportation systems have been gradually applie...
