Abstract

The invention discloses an intelligent road abnormal event detection management device which comprises a field road camera group, a background server, an application program interface and a road abnormal event management platform. The field road camera group is connected with the background server through a data bus and an address bus, and the road abnormal event management platform calls a pre-programmed application program interface through an Internet TCP / IP protocol to send and receive data of the background server; the invention also discloses an intelligent road abnormal event detectionmanagement method based on deep learning, and the method comprises the following steps: reading the state of the road monitoring camera; monitoring images are captured in a multi-thread mode accordingto a snapshot strategy for image processing, road object detection, whether road conditions are abnormal or not, image road surface segmentation, whether a camera moves or not, abnormal secondary detection, early warning record generation and early warning information sending; according to the invention, the problems of inaccurate and incomplete road abnormal event detection and low universalityin the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of road abnormal event detection, and in particular relates to a road abnormal event detection management device and a method thereof. Background technique [0002] The real-time detection and management of expressway abnormal events is very necessary for road transportation safety, traffic management, road safety precautions, driving route planning and other fields. According to the different detection methods, common expressway abnormal event detection can be divided into three methods: the method based on vehicle GPS positioning, the method based on vehicle speed and the method based on video images. [0003] The method based on vehicle GPS positioning is most used in the detection of abnormal road events. Using the on-board positioning device to obtain the spatial location information at different times, through the analysis and mining of massive floating car trajectory information, the detection method...
