Abstract
The utility model provides a traffic speed of a motor vehicle detects and snapshot system based on TOF camera, includes a central processing unit, TOF camera and high definition camera. A central processing unit acquires the depth information of scene from the TOF camera, through handling, obtains the real time speed and the position of vehicle in the scene to send to the high definition camera and take a candid photograph the instruction. This system uses the TOF camera, can once only obtain complete depth information in the scene, and then obtains the result that tests the speed of high accuracy, to bad weathers such as heavy rain dense fogs, this system still has higher interference killing feature, in addition, this system implementation the full automation who tests the speed and take a candid photograph, can realize control in 24 hours to the road, greatly practiced thrift manpower resources.
Description
Technical field
The utility model relates to a kind of traffic Bus-Speed Monitoring based on TOF camera and capturing system, belongs to traffic information investigating field.
Background technology
Along with the development of society, the raising of people's living standard, increasing person selects a good opportunity this trip mode of motor-car, vehicles number on urban road increases severely, thus just seem particularly important for the Information Statistics of vehicular traffic with supervision, wherein, driving over the speed limit is endanger a larger class, and the Bus-Speed Monitoring and the candid photograph that how to realize robotization become an important topic.
At present, vehicle speed detector device conventional on road has following several: velocity radar, the laser instrument that tests the speed, inductive coil, ultrasonic velocity meter, binocular camera etc., but more or less has such as: equipment cost is high, rate accuracy is low, constructional difficulties, algorithm complex are high, by shortcomings such as adverse weather conditions are large.TOF camera is as the one of depth camera, use TOF (Timeofflight) technology, initiatively launch near infrared light to search coverage, camera sensor is launched by compute ray and reflection interval is poor or phase differential, convert and be detected the distance of object, be i.e. depth information.TOF technology and 3D laser sensor principle substantially similar, only 3D laser sensor is point by point scanning, TOF camera is then the depth information simultaneously obtaining entire image, relative to 3D laser instrument, the advantage that TOF camera has investigative range wide, thus has great advantage on vehicle speed measuring, and remains laser velocimeter by the less advantage of adverse weather conditions, and relative to other speed measuring devices, TOF camera have easy for installation, equipment cost is low, rate accuracy advantages of higher.
Utility model content
The utility model object be to provide a kind of easy for installation, rate accuracy is high, by the little Bus-Speed Monitoring of weather effect and capturing system.
For achieving the above object, the utility model provides following technical scheme:
Based on traffic Bus-Speed Monitoring and the capturing system of TOF camera, comprise CPU (central processing unit), TOF camera and high definition camera, wherein, CPU (central processing unit) is connected with TOF camera, high definition camera respectively.
Described TOF camera, in its search coverage, (speed trial ground) gathers depth information of scene continuously, and real-time Transmission is to CPU (central processing unit).Described speed trial ground is TOF camera coverage, is at least 2 meters being parallel to width on garage direction, is positioned at immediately below described TOF camera installation site, front or rear.
Described CPU (central processing unit), obtains the depth information of current scene, through algorithm process, draws real-time speed and the position of vehicle in scene from TOF camera, send capture instruction to high definition camera.
Described high definition camera, after obtaining candid photograph instruction from CPU (central processing unit), in its overlay area, (candid photograph district) completes the candid photograph to vehicle, and candid photograph result is returned to CPU (central processing unit).Described candid photograph district, is the overlay area of high definition camera, is positioned at the front of speed trial ground direction of traffic, is not less than 3 meters being parallel to width on garage direction.
The beneficial effects of the utility model are as follows: the TOF camera that native system uses, and use TOF technology, disposablely can obtain depth information complete in camera covering scene, thus can obtain the result that tests the speed that precision is very high; For inclement weathers such as heavy rain dense fogs, native system also has higher antijamming capability; In addition, native system also achieves the full automation of measuring speed and taking snap pictures, can realize monitoring in 24 hours, greatly saved human resources to road.
