Embodiment

[0079] Such as Figure 4 As shown, a kind of intelligent road abnormal event detection and management device includes on-site road camera group 401, background server 402, application program interface 403, road abnormal event management platform 404; described on-site road camera group 401 communicates with The background server 402 is connected, and the road abnormal event management platform 404 invokes the pre-programmed application program interface 403 through the Internet TCP / IP protocol to send and receive data from the background server 402;

[0080] The on-site road camera group 401 is used to collect road scene pictures in real time; the on-site road camera group 401 has an imaging pixel of more than 4 million pixels and a resolution of more than 1920×1080;

[0081] The background server 402 is preset to train two kinds of CNN convolutional neural networks based on deep learning, and carries out road abnormal event detection and data storage for the on-site road pic...

Abstract

The invention discloses an intelligent road abnormal event detection and management device, which includes an on-site road camera group, a background server, an application program interface, and a road abnormal event management platform; the on-site road camera group is connected to the background server through a data bus and an address bus, and road abnormal event management The platform invokes a pre-programmed application program interface through the Internet TCP / IP protocol to send and receive background server data; the invention also discloses a method for detecting and managing intelligent road abnormal events based on deep learning, which includes the following steps: reading road monitoring Camera status, according to the capture strategy, multi-threaded interception of monitoring images for image processing, road object detection, whether the road condition is abnormal, image road surface segmentation, whether the camera is moving, abnormal secondary detection, generation of early warning records, and sending early warning information; There are problems of inaccurate, incomplete, and low versatility in the detection of abnormal road events by technology.

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...
