Brief description
Fig. 1 is for realizing the synchronous system architecture schematic diagram of light filling between intelligent camera in the electronic police system of the present invention.
Specific embodiment
In order to be more clearly understood that the technology contents of the present invention, describe in detail especially exemplified by following examples.
Refer to shown in Fig. 1, in this electronic police system, realize the synchronous system of light filling between intelligent camera, including
Panoramic camera and several number plate video camera, each number plate video camera is provided with corresponding light compensating apparatus and Comprehensive Control mould
Block, and described panoramic camera is connected with panorama comprehensive control module, each described comprehensive control module is comprehensive with panorama
Control module is all connected with each other by bus, described each comprehensive control module respectively with each self-corresponding number plate video camera and
Light compensating apparatus are all connected.
Wherein, described comprehensive control module includes central control unit, shooting driver element and light filling driver element, institute
The central control unit stated is connected with described number plate video camera by described shooting driver element, and this central authorities controls list
Unit is connected with described light compensating apparatus by described light filling driver element；Described panorama comprehensive control module includes central authorities
Control unit, panoramic shooting driver element, described central control unit pass through described panoramic shooting driver element with described
Panoramic camera be connected.
Meanwhile, described light compensating apparatus are stroboscopic lamp, and described bus is fieldbus, described each Comprehensive Control mould
Block is connected with each self-corresponding number plate video camera by universal serial bus respectively.
The method that light filling synchronization between intelligent camera in electronic police system should be realized based on above-mentioned system, including
Following steps：
(1) system carries out Initialize installation, and described panoramic camera is arranged on triggering candid photograph pattern, and will be described
Number plate video camera is arranged on continuous candid photograph pattern or triggering candid photograph pattern；
(2) when needing to be captured, by described number plate camera switching to triggering candid photograph pattern；
(3) the number plate video camera described in sends synchronous grab signal by corresponding comprehensive control module and bus, and prolongs
The time delay of a slow systemic presupposition；Typically not greater than 1 millisecond of this time delay；
(4) the panorama comprehensive control module described in receives synchronous grab signal from bus, and is converted to candid photograph triggering
Signal, delivers to described panoramic camera；
(5) panoramic camera described in is captured process operation accordingly according to this candid photograph trigger；
(6) the number plate video camera described in is captured process operation, corresponding synthesis simultaneously after postponing to terminate accordingly
Control module drives corresponding light compensating apparatus to carry out light filling operation, and this light compensating apparatus carries out light filling operation, specially：
Stroboscopic lamp is flashed at least one times.
Actually used central, the realization of the present invention is based on these points content：
● intelligent camera has several operational modes, continuously captures pattern and triggering candid photograph pattern.Triggering therein is captured
Pattern, can be after receiving trigger, and realization quickly is captured.The delay time of this process be have 1 millisecond with
Interior；
● intelligent camera provides several triggering patterns, including serial ports triggering and hardware trigger.Whether therein which
One kind, all adopts interrupt mode, can handle it immediately upon receipt of the signals；
● the application of fieldbus, communication link can be formed between multiple video cameras, and very short leading to can be realized
Letter postpones.Particularly for the video camera on a direction, traffic rate even can reach 500kps.And provide perfect
Basic communication protocol so that can without voluntarily write correlation basic communication protocol software；
Therefore, the system based on the present invention carries out the synchronous process of light filling between video camera and is realized in：
Panoramic camera operates in triggering candid photograph pattern, and number plate video camera then may operate in continuous candid photograph pattern or touches
Send out candid photograph pattern.When there is candid photograph request, after number plate camera switching to triggering pattern, synchronization being sent by fieldbus and believing
Number, and postpone a period of time.As foregoing teachings, number plate video camera is same between both by realizing this section of time delay
Step.Because the time of light compensating lamp flicker is very short, and the time of exposure of video camera is typically all long.As long as therefore exposing in video camera
In the process of light, the flicker completing a light compensating lamp completes once effectively light filling.Also just because of this tolerance value, make
Being synchronously possibly realized between panoramic camera and number plate video camera.
Refer to shown in Fig. 1, panoramic camera can distinguish synchronous four number plate video cameras, with its shared light compensating lamp.Tool
The technology by fieldbus for the body, synchronous candid photograph instruction is sent to panoramic camera by number plate video camera.Meanwhile, number plate is taken the photograph
Start after one fixed value of camera time delay to capture, you can to complete synchronization between the two.Comprehensive control module work(in system
It can be the serial ports trigger message that fieldbus information is converted to video camera.
Employ and in above-mentioned electronic police system, realize the synchronous system and method for light filling between intelligent camera, due to it
In between intelligent camera cannot stationary problem, there is provided the synchronization mechanism between corresponding video camera so that
Panoramic camera can synchronously go up the number plate video camera on each track, and the supplementary lighting module of shared number plate video camera, effectively subtracts
The light filling expense of few panoramic camera, it is not required that there being extra light filling switched system particularly in the case of multiple tracks,
And simple and practical, cost is relatively low, stable and reliable working performance, and the scope of application is relatively broad.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that still can make
Various modifications and alterations are without departing from the spirit and scope of the present invention.Therefore, specification and drawings be considered as illustrative
And it is nonrestrictive.
