Description

Image acquisition device for traffic signal lamp control system

Technical Field

The utility model belongs to the information acquisition field, concretely relates to an image acquisition device for traffic signal lamp control system.

Background

In recent years, city construction in China is developed rapidly, however, city problems come with the city, the first problem is urban traffic jam, and the urban traffic jam is more and more serious due to the fact that the number of urban motor vehicles rapidly rises to cause the traffic flow to increase rapidly. Some experts and scholars think that: the traffic jam phenomenon is more and more serious due to the problems of insufficient traffic infrastructure, excessive number of automobiles, unreasonable traffic layout and the like; the source of urban traffic problems is the imbalance between traffic demand and traffic supply. They also propose a number of methods to solve the traffic congestion problem, such as: a new road is built, a local area network, an RFID system (radio frequency wireless signal automatic identification system) and the like are used, but a new road cannot be built because there is not enough building space, and the cost for applying an RFID sensor and a local area network system at an intersection is much higher than that of a current traffic signal lamp system.

The traffic signal lamp problem is mainly caused by the fixed traffic signal frame at the road intersection. These signals do not take into account the actual situation of the road, but a fixed signal time is set for each road, leading to a number of problems. In areas with large pedestrian volume, the traffic delay problem is caused by great influence on life, work and even safety and health of people in the areas, due to the influence of traffic peaks in the morning and at night, people cannot finish work according to an expected plan, and people cannot predict the travel time of people, so that more things to be handled by people in daily life are directly influenced. Another problem is that the vehicle can stop and start at the intersection, which directly results in higher fuel consumption than during normal driving. As the amount of fuel consumed increases and the cost of fuel increases, additional payment for fuel is required, and global warming is aggravated by a large amount of air pollution. In addition, the problem has a greater negative effect in case of emergency, and the fire engine and the ambulance cannot react at a proper time. In the case of an ambulance, the patient on the road is in a critical situation, but traffic congestion makes it very likely that the ambulance will not be able to reach the hospital at the right time, which could lead to a life-threatening situation for the patient. This is why an intelligent traffic control system is required to effectively cope with different traffic conditions and avoid traffic jams and accidents.

The main modules of the intelligent traffic monitoring system shown in fig. 7 include: vehicle type, length, traffic, route, traffic police and direction management. The utility model discloses the people utilizes the self-adaptation intelligent traffic light control system who proposes (AITLCS) to control the traffic light to utilize the image to detect vehicle density; the method for processing the lane images shot by the digital camera comprises the following steps: operations such as sharpening, blurring, brightening, edge enhancement and the like; the images are then analyzed in groups using computer imaging techniques to find vehicles and controlled by operating conditions and moving lights. The image processing tool used in the study was a free, non-commercial, Intel-sourced, computer vision library, OpenCV.

The image acquisition device is as the key spare part in the traffic control system, image acquisition's definition has directly influenced control system's precision, nevertheless because it is in direct exposure in the environment, can receive the pollution of the dust in the environment by difficulty, the dust adheres on the camera lens dustcoat, cause the camera lens dustcoat to be vague, this just needs a real-time cleaning equipment can simply clear up it rapidly, and image acquisition device is difficult to normal work among the cleaning process, therefore, how compromise above-mentioned two kinds of circumstances, just the problem that the scheme of this paper will be solved.
