Embodiment:
As depicted in figs. 1 and 2, the infrared separation autotracker of whole audience scape of the present utility model is by infrared launcher 1, infrared acquisition equipment 2, infrared analysis device 3 and autotracker 4 constitute, wherein, described infrared launcher 1 is made of the infrared and radio microphone, described infrared acquisition equipment 2 is made of whole audience scape thermal camera and filtering card, described filtering card is arranged in the whole audience scape thermal camera, described infrared analysis device 3 is made of computer, whole audience scape thermal camera is connected with described infrared analysis device 3 by holding wire, described autotracker 4 comprises takes video camera and automatically controlled The Cloud Terrace, described shooting video camera is arranged on the automatically controlled The Cloud Terrace, infrared analysis device 3 is connected with automatically controlled The Cloud Terrace with the shooting video camera by control line, and the visual field of whole audience scape thermal camera intersects with the infrared coverage of infrared and radio microphone or overlaps.
The course of work of present embodiment is: the infrared and radio microphone is launched infrared signal in guarded region, and infrared signal is the region of ultra-red of forming with infrared point.Whole audience scape thermal camera covers whole audience scape, obtains whole audience scape imaging surface.The filtering card filters other light, only stays infrared light spectral coverage light, and the infrared signal of being made up of infrared ray enters infrared analysis device 3.After 3 pairs of infrared signal imaging surfaces of infrared analysis device are analyzed, determine region of ultra-red, again positional information is passed to autotracker 4.Shooting video camera in the autotracker 4 is under automatically controlled The Cloud Terrace drives, and suitable displacement is adjusted in the suitable displacement of horizontal direction adjustment on the vertical direction, adjust focal length simultaneously, makes the shooting video camera reach best shooting angle.
Have much by infrared signal in the infrared acquisition equipment 2 resulting imaging surfaces of whole audience scape, infrared analysis device 3 analyzes the region of ultra-red that satisfies condition (region of ultra-red that is sent by infrared launcher 1) position, simultaneously this zone position information is passed to tracking means.
(1) analysis of infrared signal imaging surface
3 pairs of infrared signal imaging surfaces of infrared analysis device are analyzed, and its size is M (pixel) * N (pixel).Device is divided into m*n block of pixels with imaging surface, and (m is capable, n row, m＜=M wherein, n＜=N).Can determine a key point a in each block of pixels
i(0＜i＜=m*n, i are integer), the coordinate figure of key point in imaging surface can full identity come out.As shown in Figure 3.Infrared analysis device 3 directly is associated these key points with tracking means, can obtain the moving parameter (x of the pairing tracking means of each key point
i, y
i, f
i).When device initially uses, the moving parameter of the tracking means of part key point only need be set, the key of required setting is counted smaller or equal to 16.Infrared analysis device 3 according to generating algorithm, generates the moving parameter of the correspondence of all key points according to the key point that is provided with and corresponding moving parameter thereof automatically.That is to say and generated infrared correspondence table this moment, be i.e. key point a
1, the moving parameter (x of corresponding tracking means
1, y
1, f
1), key point a
2, the moving parameter (x of corresponding tracking means
2, y
2, f
2), by that analogy.
(2) region of ultra-red determines
The infrared signal that is obtained by infrared acquisition equipment 2 can enter into infrared analysis device 3 automatically, is detected the particular location of infrared signal by this device.The definite of infrared signal position finished by series of steps, and these steps are target with the region of ultra-red of determining to satisfy condition.Following condition is carried out one by one, carries out region of ultra-red and detects.
1. region of ultra-red must be in the imaging surface, gets rid of the fixedly region of ultra-red (as fixed light sources such as light) in the imaging surface.
2. satisfy condition region of ultra-red in 1. the imaging surface, infrared point quantity is more than or equal to a certain designated value M, and the infrared point brightness value is more than or equal to a certain designated value N.(wherein, designated value M, N are specifically set by site environment)
3. in the region of ultra-red that above-mentioned two conditions all satisfy, detect the region of ultra-red that satisfies given shape and size.(shape and size are determined according to infrared launcher 1)
4. in the region of ultra-red that above-mentioned three conditions all satisfy, in the remaining region of ultra-red, detect infrared point b the brightest in the zone
i(i is an integer).
5. infrared point b
iThe region of ultra-red at place is the region of ultra-red that satisfies condition.That is to say the region of ultra-red that infrared analysis device 3 will be determined.
(3) determine tracing positional, transmit control signal
The azarin exterior point b that infrared analysis device 3 analyzes
iThe region of ultra-red at place must be presented on the imaging surface, and must drop in certain block of pixels, as shown in Figure 4.B in imaging surface
iCoordinate can obtain.In infrared analysis device 3, search infrared correspondence table according to coordinate, can calculate infrared point b
iThe moving parameter of the tracking means correspondence of the region of ultra-red correspondence at place (x, y, f).These three parameters can drive tracking means and carry out horizontal level, and the adjustment of upright position and focal length thereof reaches the tracking to region of ultra-red, that is to say the region of ultra-red of infrared launcher 1 is finished tracking.
