Abstract
The invention provides a target-tracking system, which comprises a light emitter, a sensor, a control unit, a data transmission unit and a computer terminal; the light emitter is used for emitting optical pulse signals to a target to be detected and a background; the control unit is connected with the light emitter and the sensor, and is used for controlling the sensor to sequentially scan a plurality of image acquisition areas under two types of optical pulse signals in turn in order to acquire images containing dark and bright alternate pattern units and identifying the images containing the dark and bright alternate pattern units in order to differentiate the target to be detected from the background; and the sensor which comprises the image acquisition areas is used for acquiring the images of the target to be detected and the background. The implementation of the target-tracking system can effectively solve the problem that tracking cannot be accurately carried out due to the severe interference of sunlight, and moreover, the system is easy to put into practice and operate.
Description
Technical field
The present invention relates to target tracking domain, more particularly, relate to a kind of target tracker.
Background technology
Because contain the light of various wave bands in the daylight, target tracker is easy to receive the particularly influence of sunshine of extraneous light.Target tracker if target to be measured has strong bias light, particularly receives sunshine or high light direct projection in outdoor application, and the accuracy of then measuring will be had a strong impact on.
The prior art scheme that solves the sunlight interference mainly contains following two kinds: first kind is to block device through adding filter plate or adding sunshine, filters visible light, only keeps the light signal of required wave band.This method can not tackle the problem at its root, and the filtering meeting causes sensitivity to reduce, so system need improve emissive power, and the sensitivity that balancing out filters causes descends.In addition, system adds filter plate or blocks device increases system cost, uses inconvenient.Second kind is that infra-red (IR) decoding circuit is carried out signal compensation, eliminates the interference of external light source.This kind equipment is complicated, and cost is high, is not easy to realize.
Summary of the invention
The technical matters that the present invention will solve is, tracking target object under the high light background to the complicated defect of high cost of the said equipment of prior art, provides a kind of target tracker.
The technical solution adopted for the present invention to solve the technical problems is; A kind of target tracker is provided; This device comprises light emitting devices, sensor, control module, data transmission device and terminal, and light emitting devices is used for the light emitting devices to target to be measured and background emission light pulse signal; Control module links to each other with sensor with light emitting devices; Being used to control sensor alternately scans above-mentioned a plurality of image acquisition region under two kinds of light pulse signals successively; Obtaining to contain the image of light and dark pattern unit, and the above-mentioned image that contains light and dark pattern unit is discerned to distinguish the control module of said target to be measured and said background; Sensor is used for said target to be measured and said background are carried out the sensor that comprises a plurality of image acquisition region of IMAQ.
In described target tracker, a plurality of image acquisition region that said sensor comprises.
The target tracker of embodiment of the present invention has following beneficial effect: efficiently solve in the conventional target tracking technique because a difficult problem that can not accurately detect by the sunshine serious interference.Equipment of the present invention does not need extra filter plate or other radical occlusion device of adding, and does not need the complex design circuit to come signal is compensated yet, but only needs control light emitting devices and sensor working to get final product, and equipment is realized easily, and is simple to operate.

Embodiment
The light that comprises various wave bands in the daylight is like ruddiness, blue light, purple light etc.Therefore, under high light or daylight background, target tracker is easy to receive the particularly influence of sunshine of extraneous light.
The structural representation of Fig. 1 target tracker of the present invention.As shown in the figure; The present invention provides a kind of target tracker; This device comprises light emitting devices, sensor, control module, data transmission device and terminal; Light emitting devices is used for the light emitting devices to target to be measured and background emission light pulse signal, and the pulse signal here comprises first light intensity and the second light intensity light pulse signal, and first light intensity and second light intensity are unequal; Difference between the two should make and when carrying out IMAQ, can distinguish that said target to be measured is also different to the reflection potential of said light pulse signal with said background; Control module links to each other with sensor with light emitting devices; Being used to control sensor alternately scans above-mentioned a plurality of image acquisition region under said first light intensity and said second light intensity successively; To obtain to contain the image of light and dark pattern unit; And the above-mentioned image that contains light and dark pattern unit discerned to distinguish the control module of said target to be measured and said background, comprise control module, analysis module and memory module in the control module; Sensor is used for said target to be measured and said background are carried out the sensor that comprises a plurality of image acquisition region of IMAQ.In practical operation, can make that the difference between first and second light intensity is maximum, be convenient to the image recognition in later stage there being one to be preferably zero in first light intensity or second light intensity.
Above embodiment has only expressed preferred implementation of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention; Therefore, all the claim scope is done according to the present invention equivalents and modification all should belong to the covering scope of claim of the present invention.
