Method and system for detecting red light running based on complex high-dynamic environmental modeling

Abstract

The invention discloses a method and a system for detecting red light running based on complex high-dynamic environmental modeling. The method comprises the following steps of 1) calibrating intersection pictures; 2) performing background modeling on the intersection pictures by using a gaussian mixture model; 3) performing illumination detection and analysis on the modeled background, and updating the background so as to obtain the exact background pictures of a current intersection; 4) obtaining the tracking information of vehicles at the intersection according to background subtraction and tracing algorithm treatment; and 5) judging whether the vehicles run the red light according to the tracking information and calibrating pictures of the vehicles. The system based on the method comprises a camera device and a control device, wherein the camera device is connected with the control device, and sends the shot intersection pictures to the control device; and the control device performs the background modeling on the shot intersection pictures by using the gaussian mixture model, performs illumination detection and analysis on the modeled background, and judges whether the vehicles run the red light. By the method and the system, the background can be rapidly and exactly updated; the accuracy and adaptability of red light running detection can be improved; and the method and the system are suitable for various complex environments.

Description

technical field [0001] The invention belongs to the field of traffic image processing, in particular to a method and system for detecting red light running based on complex and high dynamic environment modeling. Background technique [0002] The traffic problems caused by economic development have become a common problem in cities. China is a developing country with sustainable economic development, with rapid urbanization and automobileization. In order to solve a series of problems caused by this, it is necessary to increase the investment in transportation facilities and accelerate the construction of transportation supply; more importantly, it is necessary to use the existing road transportation facilities scientifically and rationally to play their greatest role. However, the traditional detection method of running a red light using a ground sense coil has the disadvantages of high cost and difficult maintenance. Recently, the video detection method that has been spawn...

Problems solved by technology

However, for environments with high dynamics and complex lighting changes in the city, there will be situations where the environment changes before the background is updated. The mixed Gaussian model has the result of constantly building new Gaussian bodies and struggling between various changes. Cannot achieve the purpose of real-time and accurate monitoring
