The above-mentioned autotracker based on infrared thermal imaging, also comprise external memory storage, is embedded in described image processing module, to deposit real-time front end image.
The accompanying drawing explanation
Fig. 1 is the theory diagram according to a kind of autotracker based on infrared thermal imaging of the present utility model.
Fig. 2 is the method flow diagram from motion tracking.
Embodiment
In structure as shown in Figure 1, a kind of autotracker based on infrared thermal imaging, its basic structure should comprise:
The Cloud Terrace 2, as carrier, should meet load and be less than its maximum load capability, and simultaneously, its luffing angle and the level angle cruised should meet field working conditions, to this those skilled in the art, should have clearly and understand.
About The Cloud Terrace 2, be here to carry thermal infrared imaging camera 1 naturally, join the team and The Cloud Terrace 2 is carried out to the angular range of angle location: 0 ° ~ 360 ° of levels, luffing angle-45 ° ~ 45 °, to meet thermal infrared imaging camera 1 Real-time Collection front end image.
About The Cloud Terrace 2 load capacity, depend primarily on the load of carried thermal infrared imaging camera 1 self and because the dynamic loading that acceleration-deceleration produces, and the maximum load under the coefficient of safety condition, and need to consider that cable connects the additional load produced.
For forming nominal closed-loop system, the configuration intelligent device, image processing module 7 as shown in Figure 1, connect described thermal infrared imaging camera 1 by video interface, the front end image gathered to obtain described thermal infrared imaging camera 1.
Should be appreciated that merely can be CPU, MCU, dsp chip with regard to intelligent device, can be also " machine " that disposes memory, peripheral interface circuit, as single-chip microcomputer etc.In structure as shown in Figure 1, between image processing module 7 and memory 8, can have inclusion relation, also can independently exist, to this, image processing module 7 should have different understanding, but does not affect determining of protection range at this.
So just can form the major part of nominal closed-loop control.
The configuration feeder line, connect described image processing module 7 and described The Cloud Terrace 2, with the location according to described positioning instruction FEEDBACK CONTROL The Cloud Terrace 2.
In above-mentioned structure, realize the accurate location of The Cloud Terrace 2 by simple closed-loop control, and realize under the state lower at irradiation intensity realizing the tracking to target by means of thermal infrared imaging camera 1.
In the structure shown in Fig. 1, described feeder line is the serial communication data wire, and correspondingly, image processing module and The Cloud Terrace adaptation have serial communication interface, communication port 4 as shown in Figure 1 and communication port 5.
Owing to just setting forth control command, therefore, optional telecommunication cable scope is wider, but, for the ease of making, preferably adopts the serial ports of standard, as described in serial communication interface be RS422 or RS485, cost is not high yet, and convenient the making.
In order to facilitate wiring, for the interface circuit of described video interface, comprise the The Cloud Terrace repeat circuit.
Preferably, also comprise external memory storage, be embedded in described image processing module, to deposit real-time front end image, in order to consulting.
About described thermal infrared imaging camera 1, preferably adopt the video camera with auto-focus function, to obtain mass ratio image preferably.
So according to said structure, the infrared thermal imaging video forwards by The Cloud Terrace the video input mouth 6 that mouth 3 exports image processing module 7 to, image processing module 7 is according to the tracking plan arranged, time opening following function video recording, video file is placed on to memory 8(external memory storage, and template file is deposited in internal storage) in.If detecting target, image processing module 7 will do further processing, the final COM port 4 that sends The Cloud Terrace positioning command road The Cloud Terrace 2 by its COM port 5, so cycling guarantee target always in video image, realize target is followed the tracks of.
During work, at first The Cloud Terrace 2 carries out Power-On Self-Test with thermal infrared imaging camera 1, then opens image processing module 7, and what image processing module 7 just can be according to following function after starting fully arranges the execution tracing task, and the location that completes The Cloud Terrace, by the final realize target of real-time positioning cradle head, follow the tracks of.
As shown in Figure 2 be the flow process of image processing module, its step is as follows:
The first step, open automatic tracking function after this module work, and open recording function.
Second step, gather the infrared thermal imaging video image.
The 3rd step, carry out target detection to the infrared thermal imaging video image gathered, and obtains one or more targets.
The 4th step, according to the template of the target defined in program, mate one by one, if not coupling get back to second step and continue to process, if the target of one or more couplings were arranged would pick out the most close one as final goal, and proceed to the 5th step execution.
The 5th step, the target drawn according to the 4th step, carry out the calculating of target location, finally obtains the deviation angle (angle of visual field of supposition thermal infrared imaging camera fix) of target with respect to the thermal infrared imaging camera dead ahead.
The 6th step, the relativity shift angle drawn according to the 5th step, send positioning command to The Cloud Terrace, again makes target localization to infrared thermal imaging video image zone line, reaches the tracking purpose, returns to second step and continue to carry out.
