Accurate and rapid road violation and parking full-automatic snapshot system

Abstract

The invention provides an accurate and rapid road violation and parking full-automatic snapshot system. The system comprises a front-end monitoring point part, a network transmission part and a centermanagement unit. The vehicle detection technologies mainly comprise the vehicle dynamic detection technology and the vehicle tracking technology. A matched vehicle tracking method is estimated by utilizing the motion detection method based on time-based motion historical images and feature-point optical flows. In order to achieve a better motion detection effect, a shadow removing method is usedand a moving vehicle is more accurately detected. The multi-feature point optical flow detection tracking mode is adopted, and the tracking accuracy is obviously improved in combination with a vehicleshielding solution. The system is powerful in function and is sufficient to meet the requirements of various application occasions. By adopting the system, the functions of the remote control on a ball machine at a front end monitoring point, the previewing of the video monitoring, the automatic detection of the illegal parking, the automatic identification of license plate numbers, the association of the high-definition video recording with illegal behavior videos, the storage and the browsing of the vehicle information, the system management, the remote maintenance and the like are realized.

Description

technical field [0001] The invention relates to an automatic capture system for illegal parking, in particular to an accurate and fast automatic capture system for road illegal parking, which belongs to the technical field of intelligent processing of road traffic violations. Background technique [0002] With the development of social economy and the improvement of people's living standards, the number of motor vehicles in cities has increased rapidly, and the rapid growth of parking demand does not match the supply of parking lots, and the contradiction between supply and demand of parking has become increasingly prominent; at the same time, because of traffic safety awareness of motor vehicle drivers Indifferently, illegal parking of motor vehicles has become a chronic disease in the city. Every year, there are millions of traffic jams and rear-end collisions caused by illegal parking, which seriously affects the overall traffic environment of the city and will cause peopl...

AI Technical Summary

Problems solved by technology

[0006] First, in the actual monitoring scene, there are many interferences from changes in external factors, such as environmental lighting changes, including light gradients and light mutations, etc.; motion changes, camera position shake caused by bad weather, and background objects such as leaves and ripples. Sexual movement, etc.; background shape changes, new objects stay in the scene or background objects leave the scene, which is particularly prominent in traffic scenes for illegal parking detection

[0007] Second, there are still many difficulties in vehicle detection, including the impact of dynamic scenes. In actual traffic monitoring scenes, background images are often not static, such as lighting changes in the scene, shaking flags and trees, and camera shaking. These dynamic backgrounds are easily mistaken for moving targets, resulting in large-scale complex interference, which seriously increases the difficulty of vehicle detection; the influence of occlusion and adhesion, the occlusion between objects will cause objects to stick to each other, these Both will cause difficulties in feature matching in target tracking. When there are multiple objects in the video image, there will inevitably be occlusion and adhesion between each other; the influence of moving shadows, in traffic scenes, shadows often appear with moving vehicles

The moving object detection algorithm will mistake moving shadows for moving vehicles, which not only seriously affects the accuracy of vehicle detection, but also each moving object will be glued together by projected shadows, which will interfere with vehicle tracking.

[0008] The third is the target tracking in video surveillance technology. The main difficulty lies in the influence of external factors. There are various interferences in the background image, which are easy to produce false targets. Moreover, the phenomenon of adhesion between moving targets will occur due to projected shadows and overlapping with each other. It is very difficult to track the target; the real-time requirement of tracking, due to the huge amount of video data, it is difficult to meet the real-time requirement if an appropriate algorithm strategy is not selected

[0009] Fourth, it is difficult to realize the overall design of the automatic capture system for illegal parking, and the system architecture design, outline design, and software function realization are relatively complicated
