Embodiment Construction

[0033] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] Firstly, the background of the invention is briefly described. Existing event detection algorithms are mainly divided into direct detection methods and indirect detection methods. The direct detection method refers to the method of using digital image processing and video recognition technology to detect abnormal driving behavior of vehicles and extract traffic event information. The indirect detection method analyzes traffic parameters (such as vehicle speed, traffic volume, road occupancy rate, etc.) collected by road detectors, and indirectly identifies traffic incidents through pattern recognition or statistical analysis. The former requires complex feature extraction of the image, or requires continuous calculation and recogni...

Abstract

The invention discloses a traffic event detection method and device, a terminal and a storage medium. The traffic event detection method comprises the steps of obtaining a to-be-detected image; identifying a non-resident object in the to-be-detected image; performing three-dimensional modeling on the non-resident object in the to-be-detected image to obtain a first image; performing two-dimensional modeling on the non-resident object in the to-be-detected image to obtain a second image; and performing traffic event detection based on the first image and the second image to obtain a traffic event detection result. According to the invention, rapid detection of traffic events can be realized.

Description

technical field [0001] The present invention relates to the technical field of image recognition, in particular to a traffic incident detection method, device, terminal and storage medium. Background technique [0002] With the rapid development of my country's economic level and the continuous improvement of residents' living standards, the number of vehicles in the country is also rising. Rapidly growing traffic demand and high vehicle ownership have brought about a series of problems, such as traffic accidents, traffic congestion, etc. Therefore, comprehensive traffic safety management is needed to solve such traffic incidents. Traffic incidents refer to occasional incidents on the road, including vehicle collisions, illegal parking, falling objects, and traffic jams. [0003] When a traffic incident occurs, it is necessary to quickly deal with the traffic incident to reduce traffic delays and reduce the probability of secondary accidents. Therefore, traffic incident det...
