Problems solved by technology

These methods are very sensitive to vehicle size, vehicle attitude, shadows, illumination changes, and scene changes. They are highly dependent on the accurate establishment of samples or models, and the false detection is serious.
However, many emerging feature-based detection methods use features that are too complex or too simple, and the detection effect is heavily dependent on the quality of the collected images.
Most of the current methods have a large amount of calculation, which is difficult to meet the practical requirements

Embodiment 1

[0052] This embodiment provides a method for video detection of road traffic incidents, such as figure 1 As shown, the method includes:

[0053] S101. Acquiring scene information according to the way of PTZ camera multi-preset cruise;

[0054] To further illustrate, this step includes recording and saving the scene information of the current preset position; wherein, the scene information includes background information, environmental information, etc.; specifically, when cruising to the preset position next time, the last saved Scene information and classifier features are directly used for object detection, reducing the missed detection of objects and events in the process of switching presets.

[0055]Among them, PTZ camera tracking technology is a monitoring technology that uses image processing technology to realize target discovery and control PTZ cameras to locate, track and capture moving targets within a certain scene range. Specifically, PTZ is an abbreviation of ...

Embodiment 2

[0077] This embodiment provides a road traffic event video detection system, such as Figure 4 As shown, the system includes:

[0078] Event acquisition module 110, cruise configuration module 120, intelligent video analysis module 130, event comprehensive judgment module 140;

[0079] The event acquisition module 110 is used to obtain scene information according to the PTZ camera multi-preset cruise mode, and is also used to record and save the scene information of the current preset position;

[0080] The cruising configuration module 120 is used to set the cruising list for the cruising groups and cruising points in cruising;

[0081] The intelligent video analysis module 130 analyzes the cruising list, automatically generates a cruising execution list, Enable PTZ camera The machine performs target detection and event analysis in each preset scene according to the cruise sequence ;

[0082] The event comprehensive judgment module 140 is used for carrying out traffic a...

Abstract

The invention discloses a video detection method and system of a road traffic incident. The method comprises: scene information is obtained according to a multi-preset-position cruising mode of a PTZcamera; a cruise list is set for cruise groups and cruise points in cruising; the cruise list is analyzed and a cruise execution list is generated automatically, so that the PTZ camera carries out target detection and incident analyses in all preset position scenes according to a cruising sequence; and then various incidents in the scenes are determined comprehensively to carry out traffic incident alarming. Therefore, various traffic incidents can be discovered in real time and thus alarming signal can be triggered timely; and the field photos are captured and real-time picture recording is carried out. With the system disclosed by the invention, occurrence of secondary accidents is avoided and incident information is obtained immediately, so that the traffic incidents are processed timely and thus traffic safety and smooth traffic are guaranteed to the greatest extent.

Description

technical field [0001] The technical field of intelligent video analysis of the present invention, in particular, relates to a method and system for video detection of road traffic incidents. Background technique [0002] With the continuous increase of urban road traffic volume, traffic accidents have increased significantly. Vehicle detection technology is the primary research topic of intelligent transportation systems, and it is the prerequisite for important applications such as traffic parameter acquisition, event detection, and security deployment. If the accident is not detected and dealt with in time, it will cause traffic congestion and the efficiency of highway traffic will be greatly reduced. Therefore, the automatic detection technology of video traffic incidents applied on urban roads is of great significance. [0003] Most of the current vehicle detection methods are based on video processing, such as traditional classifier methods, background modeling method...
