Abstract
The invention discloses an over-the-ground video monitoring and recognizing system based on a combined tracing algorithm. The over-the-ground video monitoring and recognizing system is provided with a video capturing unit and a video processing unit, wherein the video capturing unit is fixed to an unmanned air vehicle, shoots a designated low-altitude area for 24 hours or in a designated time period and captures video signals; the video processing unit preprocesses the video signals captured by the video capturing unit, and a scene locking tracing algorithm is used for separating a ground target and a background from the video signals. The video processing unit supporting the scene locking tracing algorithm is added, so that background separation and analysis are effectively performed on the ground target, and it is achieved that the designated area is known clearly around the clock in a full-time mode. Only the simple structure is added on existing equipment, and the over-the-ground video monitoring and recognizing system is low in cost and beneficial to large-scale popularization and utilization.
Description
Technical field
The present invention relates to Patent classificating number H04 electrical communication technology H04N Image Communication, as TV H04N7/00 television system H04N7/18 closed-circuit television system, the system that TV signal is not broadcasted.
Background technology
Along with the progress at full speed of unmanned low flyer, it is lower that the monitor task over the ground that what some were traditional carried out by helicopter can be given cost completely, and more convenient low flyer is flexibly carried out.But owing to being by people's remote control or even automatic Pilot, aspect video treatment of details, there is inborn defect.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of recognition system of video monitoring over the ground based on combined tracking algorithm of development has:
Video acquisition unit: be fixed on unmanned vehicle, to specifying base surface area to take, gather vision signal;
Video processing unit: described video acquisition unit is carried out to preliminary treatment to the vision signal of video acquisition unit collection; Utilize scene locking tracking algorithm Area Objects and background discretely from vision signal;
Database: resemblance and the motion feature of storing common ground target;
Ground target recognition unit: be connected with database with described video processing unit, receive the isolated ground target of described video processing unit; According to the ground target feature of recording in database, described ground target is detected.
Communication unit, transmits information by this unit in real time to remote center.
Memory cell, is connected with described video processing unit, receives the signal that also store video processing unit gathers.
Owing to having adopted technique scheme, a kind of recognition system of video monitoring over the ground based on combined tracking algorithm provided by the invention, by having added the video processing unit of a scene locking tracking algorithm, can effectively carry out on a surface target background separation and analysis, accomplish that full-time has at fingertips to specifying region round-the-clock.And just on existing equipment, increased simple structure, and with low cost, be convenient to large-scale promotion and use.
Accompanying drawing explanation
For the technical scheme of clearer explanation embodiments of the invention or prior art, introduce simply the accompanying drawing of required use in embodiment or description of the Prior Art being done to one below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is module map of the present invention
Embodiment
For making object, technical scheme and the advantage of embodiments of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is known to complete description:
As shown in Figure 1: a kind of recognition system of video monitoring over the ground based on combined tracking algorithm, has:
Video acquisition unit: in 24 hours or set period, to specifying low dummy section to take, gather vision signal;
Video processing unit: described video acquisition unit is carried out to preliminary treatment to the vision signal of video acquisition unit collection; Utilize border following algorithm from vision signal, to separate low-latitude flying thing and background;
Database: store resemblance and the flight path feature of the common flying object in low latitude, described flying object comprises: kite, birds, aircraft and helicopter;
Aircraft recognition unit: be connected with database with described video processing unit, receive the isolated low-latitude flying thing of described video processing unit; According to the flying object feature of recording in database, described flying object is detected.
Communication unit, if recognition result is aircraft or helicopter, sends warning by this unit to remote center.
Radar system: be electrically connected with described video acquisition unit; Round-the-clock and full-time scanning is carried out in spatial domain, in the time flying object having been detected, send signal to video acquisition unit, video unit is aimed at flying object and is carried out video acquisition.
Memory cell, is connected with described video processing unit, receives and store the signal that CPU gathers.
Owing to having adopted technique scheme, a kind of recognition system of video monitoring over the ground based on combined tracking algorithm provided by the invention, by having added the video processing unit of a support border following algorithm, can effectively carry out background separation and analysis to low-latitude flying thing, accomplished designated flying zone round-the-clockly, full-time has at fingertips.And just on existing equipment, increased simple structure, and with low cost, be convenient to large-scale promotion and use.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
