Preferably, when capturing for twice according to front and back, in picture, the position of vehicle can judge that vehicle is lane change in violation of rules and regulations or violation line ball, and relevant information is supplied inquiry stored in backstage.
Described scanning type laser range cells is made up of scanning type laser distance measuring sensor and mounting bracket thereof.Scanning type laser distance measuring sensor is arranged on to be forbidden directly over changing Lane line, along forbidding that changing Lane line scans.
Preferably, the sweep frequency of described scanning type laser distance measuring sensor is 50Hz, and scanning angle resolution is 0.5 degree.
Data acquisition and procession unit comprises data acquisition module, vehicle identification module.Data acquisition module is responsible for the scanning frame data obtaining described scanning type laser distance measuring sensor, the ranging data that vehicle identification module obtains according to acquisition module, judges in sensing range, whether have car to sail into, and can locate the position of sailing vehicle into.
Capture unit for receiving the trigger pip of data acquisition and procession unit, and the vehicle driven in violation of rules and regulations is captured.According to the license plate number of location recognition vehicle of the picture captured and vehicle, and by the picture captured and license plate number stored in backstage for inquiry.
The utility model beneficial effect is as follows:
Described scanning type laser range cells adopts the light source of invisible wave band to find range, and not by the impact of ambient light, is no matter daytime or evening or illumination application scenario complicated and changeable, can both identifies accurately the vehicle travelled in violation of rules and regulations.
Scanning type laser distance measuring sensor, when recognizing rule-breaking vehicle and travelling, accurately can also locate the position of vehicle in violation of rules and regulations.
Described scanning type laser distance measuring sensor have employed strict vacuumizing and waterproofing design, can not by the impact of temperature and weather, for a long time, not stable operation intermittently.
Accompanying drawing explanation
The realization flow figure of a kind of rule-breaking vehicle lane change that Fig. 1 provides for the utility model one embodiment and the capturing system that line ball travels;
A kind of rule-breaking vehicle lane change that Fig. 2 provides for the utility model one embodiment and the capturing system better scheme of installation in actual applications that line ball travels.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail below by embodiment.It should be noted that at this, the explanation for these embodiments understands the utility model for helping, but does not form restriction of the present utility model.In addition, if below in described each embodiment of the utility model involved technical characteristic do not form conflict each other and just can mutually combine.
Be illustrated in fig. 1 shown below, the realization flow figure of the capturing system that a kind of rule-breaking vehicle lane change provided for the utility model and line ball travel, ranging data is sent to data acquisition and procession unit by scanning type laser range cells, whether processing unit is identified in the plane of scanning motion according to ranging data has car to sail into and sail out of, if identified vehicle to sail into and sail out of, trigger candid photograph unit to capture, capturing unit according to the picture recognition vehicle captured is lane change in violation of rules and regulations or line ball traveling, and stores.
Be illustrated in fig. 2 shown below, a better scheme of installation of the capturing system that a kind of rule-breaking vehicle lane change provided for the utility model and line ball travel.This system mainly comprises (1) scanning type laser range cells, (2) data acquisition and procession unit, (3) candid photograph unit composition.
Described scanning type laser range cells is with the pulse of characteristic frequency Emission Lasers, and laser pulse forms (4) the two-dimensional scan plane shown in following Fig. 1 in space.Range finder module in laser ranging unit can measure laser instrument apart from the distance between each point distance measurement.When having car through out-of-date, the distance between laser range sensor and current point distance measurement can change.
Described data acquisition and procession unit by network from scanning type laser range cells receive laser sensor ranging data and give processing unit.Processing unit judges in the plane of scanning motion, whether have car to sail into and locate the position of sailing vehicle into according to ranging data.Set up the two-dimensional direct angle coordinate system in the plane of scanning motion, with immediately below scanning type laser distance measuring sensor for true origin, along forbidding that changing Lane line direction is transverse axis, perpendicular to track decompose line direction be the longitudinal axis.Distance measurement value corresponding for each analyzing spot is carried out coordinate conversion, obtains the X-coordinate value along X direction and the Y-coordinate value along y direction.When Y-coordinate value has been greater than the height threshold of specifying, namely think and car may be had to sail into; When detecting that continuous print is greater than counting of height threshold and has exceeded difference that threshold value or continuous print higher than setting be greater than the X-coordinate of the point of height threshold higher than the threshold value arranged, namely think that having a car to sail into forbids changing Lane line.Corresponding X-coordinate reflects the horizontal range of vehicle distances laser instrument.
Trigger pip is sent by when becoming without car state and have car state to capturing unit in data acquisition and procession unit inspection to the plane of scanning motion, the position of vehicle is sent to candid photograph unit simultaneously, capture unit receive trigger pip and locate according to vehicle location and capture, according to candid photograph picture recognition license plate number.When sending trigger pip without during car state to capturing unit by there being car state to become in data acquisition and procession unit inspection to the plane of scanning motion, capturing unit and capturing according to trigger pip and positional information.
Can determine that vehicle is lane change in violation of rules and regulations or line ball traveling according to the position relationship of two pictures captured.
The above is only the utility model preferred implementation; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
