Description
Technical field
The invention belongs to field of video monitoring, relate to the linkage display of panorama and local detail picture, particularly make full use of this tripod head equipment of presetting bit and carry function, realize the method for high efficiency panorama and the distributed linkage display of local detail picture.Also relate to a kind of device adopting presetting bit to realize panorama and the distributed linkage display of local detail picture.
Background technology
Panorama Display Technique utilizes multiple fixed cameras to obtain original image, then by video processnig algorithms, permeate multi-channel video splicing width seamless panorama picture, for checking the entirety of supervision scene.Monopod video camera (PTZ) has the feature such as omnibearing movable, adjustable focus, convergent-divergent up and down, is the conventional a kind of surveillance equipment in current video monitoring field.The conbined usage of panorama Display Technique and monopod video camera, can facilitate user to hold while Global picture and local detailed information.Current, panorama and monopod video camera picture are simple display separately mostly, do not relate to interlock.Also there is the system of similar 3D intelligent positioning in present stage, current picture is clicked by mouse, system presents the local detail information of mouse click location automatically, but in the method, Global picture and local detail picture are all obtained by monopod video camera, also do not relate to interlock, therefore, can not show Global picture and local detail picture, and the visual range of monopod video camera splices the panorama obtained much smaller than multiple fixed cameras simultaneously.In addition, have also appeared such interlock method, namely be utilize the fish-eye fixed cameras of band to check panorama, monopod video camera is utilized to present local detail picture, interlock each other is also clicked by mouse and is realized, but the panorama that fish eye lens obtains has distortion, do not splice by multiple fixed cameras the picture obtained true and clear, simultaneously, there is strict demand the position of the method to monopod video camera and fixed cameras, normally form spherical all-in-one, because the method utilizes Mathematical Modeling and respective physical formulae discovery to go out the angle of monopod video camera to the rotation of mouse click location needs, therefore, when linking, monopod video camera movement position is estimated and position error intervention all relates to a large amount of computings, this not only lowers the speed of service, also increase the weight of equipment operating load.In addition, the structure of similar spherical all-in-one also limit monopod video camera and uses focal length zoom camera lens, viewing distance is limited, the local detail being not suitable for the large-scale depletion region such as airport, harbour is checked, the method is when showing, utilize windows exchange to show the picture of fixed cameras and monopod video camera, or do picture-in-picture display by superposing monopod video camera picture on fixed cameras picture, the inconvenient user of such display mode holds whole and part details simultaneously, and Consumer's Experience is good not.
Given this, the split screen display mode that simultaneously shows panorama and local detail picture can become a kind of practical and effective solution, prior art " a kind of distributed linked system can carried out panorama display simultaneously and check with local " (patent No.: ZL201320644149.4) is such solution.In the art, disclose a kind of distributed linked system can carried out panorama display simultaneously and check with local detail, comprise some the Still Camera towards surrounding, one is arranged on the motion cameras on all-directional tripod head, the data of described Still Camera and motion cameras pass through switch respectively successively, first optical transmitter and receiver, monomode fiber, second optical transmitter and receiver and switch are transferred in panorama main frame and local main frame, then panorama and local detail picture is demonstrated respectively by panoramic indicator and sectional displays, the rotation of panorama host computer control all-directional tripod head, panorama and local detail picture show by it on different displays simultaneously, do not need interface switching back and forth.
On the basis of " a kind of distributed linked system can carried out panorama display simultaneously and check with local ", for avoiding complex mathematical modeling in linkage process and position calculation, utilize cradle head preset positions to realize the distributed linkage display of panorama and local detail picture.Presetting bit is the function that most of The Cloud Terrace all carries, it can by the locus of current The Cloud Terrace, the state memorization such as convergent-divergent, aperture, focal length of camera lens gets off, when sending this presetting bit to The Cloud Terrace and recalling order, The Cloud Terrace, video camera and camera lens can return to the state in memory moment with the fastest speed.The current using method to presetting bit is all by pre-setting substantially, then other operation on drop-down list or software interface is utilized manually to select, when user selects to operate at every turn, need the corresponding states manually being determined presetting bit and picture by word or alternate manner, in addition, the use of current presetting bit does not yet relate to the distributed interlock with panorama.
By the analysis to prior art, known, utilize presetting bit and panorama to do to map the distributed interlock realizing panorama and local detail picture, be a kind of quick, accurate, improve the method for Consumer's Experience.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method and the device that adopt presetting bit to realize observing picture (being namely panorama and local detail picture) distributed linkage display.Make full use of the presetting bit combination shown corresponding to mapping relations, realize high efficiency panorama and the distributed linkage display of local detail picture, directly realize the interlock of panorama and local detail picture, click the locality on panorama, system background by data search, link, the step such as to call, realize the displaying to local detail picture, picture display is smooth, and Consumer's Experience is good.A kind of device realizing this inventive method is provided simultaneously.
For solving the problems of the technologies described above, the present invention provide firstly a kind of method adopting presetting bit to realize observing the distributed linkage display of picture, and the concrete steps of the method are as follows:
