Background technique
Optics motion capture is the Typical Representative of machine vision applications in recent years.Motion capture is accurately to survey in real time
The motion profile or posture of amount, record object in true three-dimension space, and reconstruction moving object is every in virtual three-dimensional space
The technology of one moment motion state.Optics motion capture is based on principle of computer vision, by multiple high speed cameras from different angles
Monitoring and tracking to target object characteristic point is spent, thus carries out the technology of motion capture.Theoretically, in space
Any one point, as long as it can be simultaneously for seen in two cameras, so that it may determine this moment position of point in space.When
When camera is continuously shot with sufficiently high rate, the motion profile of the point can be obtained by from image sequence.
With advances in technology and improvement of living standard, more and more fields start to be related to motion capture technology,
To determine the motion profile of object.
Currently, generally capturing system, acoustics formula motion capture system, electromagnetic type motion capture system using mechanical action
Etc. motion capture systems carry out motion capture, but most of motion capture systems are expensive, and maintenance cost is also high.Therefore,
How to provide it is a kind of cost is relatively low, the lower motion capture system of maintenance cost is simultaneously realized that command adapted thereto movement executes to become and is asked
Topic.
Summary of the invention
For above-mentioned deficiency in the prior art, provide that a kind of control light source captures that realization movement executes is the present invention
System.It has been given below about brief overview of the invention, in order to provide a basic understanding of certain aspects of the invention.
It should be appreciated that this summary is not an exhaustive overview of the invention.It is not intended to determine key of the invention or
Pith, nor is it intended to limit the scope of the present invention.
Technical solution of the present invention:
A kind of control light source captures the system that image realization movement executes, including light source, conjury stick, thermal camera, embedding
Enter formula work station and action actuating mechanism；
The conjury stick includes stock and the reflecting mirror for being mounted on long boom end；
There is the computer for Image Information Processing, thermal camera and movement are held inside the Embedded Workstation
Row mechanism establishes connection with computer；
The thermal camera is used to shoot the visible light source for the conjury stick end reflections mirror reflection brandished,
Image information is obtained, and the image information is sent to the computer, computer disposal identifies conjury stick reflection
Whether visible light matches with computer-internal predetermined pattern, and computer control action executing agency executes corresponding dynamic if matching
Make, system re-recognizes the visible light of conjury stick reflection if mismatching.
Preferred: the light source uses the infrared light supply of 940nm, and the infrared light supply of 940nm launches light.
It is preferred: the model M640-NIR infrared camera of the thermal camera.
Preferably, the computer determines infrared take the photograph according to its internal image information and visual light imaging location algorithm
The process for the lamp motion location information that camera reflects in conjury stick motion process, specifically includes: fixed using visual light imaging
Position algorithm, from determining the opposite of lamp motion that thermal camera reflects in conjury stick motion process in described image information
Distance and relative angle；The relative distance of the lamp motion reflected in conjury stick motion process according to thermal camera and opposite
Angle determines location information of the thermal camera in conjury stick motion process.
The invention has the following advantages:
Control light source of the invention captures the system that image realization movement executes and passes through thermal camera, Embedded Workstation
It cooperates with executing agency, determines the motion profile of conjury stick, realize motion capture, and realize that movement executes.
Since thermal camera, Embedded Workstation and visible light source are the equipment generally used, cost is relatively low, therefore
It is lower that light source captures the system overall cost that image realization movement executes, and to camera, computer and visible light source
Maintenance cost is low, therefore the overall maintenance cost of action executing system is lower.
