Description
Technical field
The present invention relates to video camera and field of video monitoring, specifically refer to a kind of presetting bit method and control system.
Background technology
The operation conditions of the key area being monitored and ball machine need to be linked together in protection and monitor field, need in back-end controller, arrange and store multiple specifically monitored regional locations, in the time that needs are monitored these regions, controller will call above-mentioned certain presetting bit setting by transmission order.And this presetting bit setting and method of calling, conventionally need in the time that presetting bit arranges, store ball machine directional information, Zoom(multiplication factor simultaneously) and Focus(gathering), and when calling only under these specific Zoom, could carry out fast and accurately presetting bit calls, in the time that arranging, presetting bit stores like this data volume large, but information is less, in the time that presetting bit is called, need accurately location of specific Z oom.
Summary of the invention
The object of the present invention is to provide a kind of presetting bit method and control system, solve the problem that can accurately carry out accurate presetting bit under the different Zoom of ball machine any direction.
Object of the present invention realizes by following technical method:
A kind of presetting bit method, comprises the following steps: presetting bit setting steps and presetting bit invocation step,
Presetting bit setting steps comprises following steps:
(A1), after system initialization, intended target is aimed in camera review center,
(A2) send out multiplication factor Zoom value under golf emitter directional information and given range to all-in-one, directional information comprises ball machine level angle and ball machine vertical angle,
(A3) all-in-one is under this Zoom value, utilizes focusing automatically to make image object clear and obtain current Focus value,
(A4) utilize current Zoom value and Focus value, according to the wire size that calculates current preset point in online number storehouse by linear interpolation method, wire size comprises Zoom value and Focus value corresponding under current directional information,
(A5) store current directional information and wire size,
(A6), according to the number in preset site, repeat (A1) step to (A5) step, the wire size formation presetting bit information table of storing directional information corresponding to all presetting bits set-point and calculating;
Presetting bit invocation step comprises following steps:
(B1), after system initialization, intended target is aimed in camera review center,
(B2) send out golf emitter directional information and arbitrary multiplication factor Zoom value to all-in-one,
(B3) when inquiry presetting bit arranges, whether directional information and the wire size of storage, there is current correspondence direction information,
(B4) if (B3) can inquire corresponding directional information, directly find out current wire size,
(B5) if (B3) can not inquire corresponding directional information, search and calculate wire size by the method for interpolation calculation,
(B6), after the wire size by (B4) or (B5) obtaining, the multiplication factor Zoom value according to wire size and (B1) is calculated corresponding Focus value, thereby obtains fast picture rich in detail,
(B7) according to specifying presetting bit to call number, repeat (B1) step to (B6) step.
Presetting bit arranges: according to the multiplication factor Zoom in ball machine directional information and given range, set current wire size.
Presetting bit is called: the ball machine directional information receiving according to all-in-one and current arbitrary multiplication factor, search the wire size of current correspondence according to correlation technique.
Specifically: aim at when intended target when camera review center, obtain directional information according to ball machine control appliance to ball machine, and Zoom value under given range, directional information comprises ball machine level angle and vertical angle.All-in-one movement, under this Zoom value, utilizes automatically focusing to make image object clear and obtain current Focus value, then utilizes current Zoom value and Focus value to calculate the wire size of current preset point according to database.Wire size is now Zoom value and the Focus value under present level angle and vertical angle, because the Focus value of the difference correspondence of Zoom value is also different, and therefore corresponding multiple corresponding Zoom value and the Focus values of shining upon one by one of this wire size information.
Described presetting bit setting need to be stored all presetting bits set-point corresponding ball machine level angle, vertical angle and the wire size calculating.
Described presetting bit is called and is included in given ball machine level, vertical angle and Zoom value, while setting according to described presetting bit, the ball machine angle information of storage and the relation of wire size are obtained current wire size, and calculate corresponding Focus value according to Zoom value and the wire size that finds, make all-in-one can clearly aim at presetting bit point of invocation.Therefore the present invention does not need to store Focus value, and Zoom value while calling can be also any Zoom value.
