Description
Technical field
The present invention relates to large-scale outdoor monitoring apparatus field, particularly a kind of remote outdoor monitoring apparatus and automatic monitoring control method.
Background technology
Along with the progress of science and technology, video monitoring system is to the development of digitlization, intelligent direction, and to combine with GIS-Geographic Information System (GIS) also be the inevitable direction of its development.Many large-scale outdoor supervision control engineerings (as forest fire protection, frontier defense patrol, maritime affairs detecting, airport security, military protection, environment monitoring etc.) generally adopt the high power pick-up lens to add the mode of The Cloud Terrace operation, monitor wider monitoring area with less headend equipment.
Large-scale outdoor supervision control engineering is valued picture quality and two indexs of target localization most, distinct image has been arranged, could lay a solid foundation, no matter be real-time supervising for the intelligent Application of system, also be based on the Intelligent Recognition of video image, the definition of image is always high more good more.
Yet, because outdoor monitoring is subjected to the influence of factors such as landform, environment, season, weather, the application level of present supervisory control system is subjected to the restriction of technical bottleneck in addition, video image instability, the picture quality of monitoring is generally lower, target location error is bigger, some new intelligent Application can't put into practice, and many users' individual demand can't be met.
Like product in the market, mainly constitute (seeing accompanying drawing 5) by outdoor control cabinet, The Cloud Terrace, video camera, wherein, outdoor control cabinet comprises compositions such as power supply, IP Process Module, The Cloud Terrace decoding card, The Cloud Terrace driver, temperature control, heater, fan, and video camera comprises high power camera lens, protective cover, warm sense, heater, windscreen wiper etc.The product of the type, though can realize control to the The Cloud Terrace level angle and the vertical angle of pitch, with the parameter of obtaining the level angle and the vertical angle of pitch; But can not realize Based Intelligent Control, and in running, the focal length of camera lens is to be obtained by camera lens automatic focus, can't realizes remote auto control, more can not obtain this parameter of real-time lens focus the camera lens zoom to camera lens.
Owing to can only preset and obtain to the level angle of The Cloud Terrace and the parameter of the vertical angle of pitch, can not the parameter of lens focus be preset and obtain, so obtaining of video image by automatically focusing and producing of video camera, the image of each target monitoring point is not clear equally, for example, image for the different depth of field of same angle, the image of the different depth of field of same angle has used identical focal length images acquired after the camera lens automatic focus, make that the image of the different depth of field obtained in same angle is not clear equally, if this image is directly used in accurate Intelligent Recognition, will make the Intelligent Recognition of image situation with wrong identification, frequent thus generation warning error occur to discern.
Simultaneously, owing to can not the parameter of lens focus be preset and obtain, make the accurate location of target become empty talk.Because present system is known to height above sea level, longitude, the latitude of current monitoring location, as under the prerequisite of current monitoring location, the level angle of the The Cloud Terrace that system can only obtain, the vertical angle of pitch, lack real-time lens focus, also just can't calculate the air line distance of current monitoring location to the target location, also just can't combine, utilize the space three-dimensional function to calculate longitude, latitude and the height above sea level of target location with the threedimensional model of GIS map.
So, product of the same type in the market is on the problem that solves target localization, adopted the method for 2 virtual location, when promptly needing to realize the location of certain target, the relevant parameter that the relevant parameter that is obtained by current monitoring point obtains in conjunction with adjacent monitoring point is virtually inferred height above sea level, longitude, the latitude that target.Because the relative complex of outdoor environment, height is straggly, and the precision of product of the same type is not high in addition, makes the level angle that obtains, the vertical angle of pitch itself with regard to inaccuracy, makes so virtually to infer that the Target Location Error that is bigger.For the monitoring point that less needs of some areas one cover monitoring equipment can be dealt with problems, target localization is not known where to begin at all.
In sum, owing to can not obtain the picture rich in detail of arbitrary target in the monitoring range, can not solve the accurate orientation problem of target, make present long-range outdoor monitoring product can only satisfy the elementary demand of outdoor monitoring, promptly can only supervise the general image of monitoring range, when the needs target localization, can only draw a relative position, even can only judge the relative bearing of target and monitoring point, and the accurate three-dimensional position position that can not obtain target.
If overcome the above problems, just must accurately control the three-dimensional parameter of monitoring point and target location, this just requires the front end watch-dog effectively to control, and can obtain the focal length of camera lens, the level angle of The Cloud Terrace, vertical these three important parameters of the angle of pitch.Like this, the user can preset the focal length of camera lens, the level angle of The Cloud Terrace, the vertical different parameter of the angle of pitch, to guarantee that monitoring objective can blur-free imaging according to the different situations of monitoring point.Yet in large-scale outdoor long-distance monitorng device field, also there is not such device at present.
