Intelligent intersection passing early warning system based on target detection

Abstract

The invention discloses an intelligent intersection passing early warning system based on target detection. The intelligent intersection passing early warning system comprises a camera acquisition module, a control module, a display module, an alarm module and a power supply module. The system can perform target detection according to pictures shot by the intersection camera, displays moving objects such as vehicles, people and animals about to arrive at the intersection and about distances to the intersection in real time through the display module, and gives different levels of warnings according to different distances. The system can be installed on a curve part with insufficient line sight distance, a position with extremely small curve radius of a road in a mountain ridge area, an intersection (especially an intersection without signals) with poor intervisibility, a railway crossing and a narrow turning position of an underground parking lot, and traffic accidents caused by the fact that vehicles at the turning intersection cannot respond in time are avoided. Compared with an existing road reflective mirror, the problems that a reflective object is distorted and deformed, the mirror surface is easy to dirty and damage, the occupied space is large, and the attention of a driver is distracted are solved. Meanwhile, a target detection algorithm is optimized, and the target detection algorithm is applied to video detection of the intersection, so that a safer, more convenient and more intelligent intersection passing early warning system is provided for automobiles and pedestrians to pass through some special types of intersections.

Description

technical field [0001] The invention relates to the fields of image recognition and intelligent transportation, in particular to an intelligent crossing early warning system based on target detection. Background technique [0002] At present, the vast majority of vehicles drive on the curve part of the route with insufficient line of sight, the extremely small curve radius of the road in the mountain area, the intersection with poor visibility (especially the intersection with no signal), the narrowness of the railway crossing and the underground parking lot. At the turn, you can only judge the situation at the intersection through the lights of the opposite vehicle, the sound of the horn, or the reflector installed at the intersection. This will cause the driver to always pay attention to some external factors, which will distract part of his attention, and may cause Surprised by sudden situations or unable to respond in time, causing safety accidents.

AI Technical Summary

Problems solved by technology

The specific application is to give early warning when the vehicles and pedestrians passing through the intersection of the construction site are abnormal. This method needs to analyze a relatively large sample data, and the processing situation will be more complicated, and the migration application effect is not good. Relatively speaking, the investment cost is relatively high. High, more helpful for analysts but less effective for actual users
