Description

A kind of device and method based on the planar light source location
Technical field
The present invention relates to a kind of method of location, relate in particular to a kind of device and method based on the planar light source location.
Background technology
Common on the market localization method has the induction location, single camera location etc., and these methods all can not be located or locate inaccurate under dark surrounds or some complex environments.
Summary of the invention
Technical matters to be solved by this invention provides a kind of device and method based on the planar light source location.
The present invention is achieved in that
A kind of device and method based on the planar light source location; Comprise a planar light source, a camera and a central processing unit are provided; On tested surface, be installed on a planar light source, camera is higher than planar light source to be placed, and is positioned at the region surface that needs detection with the viewing area that guarantees camera; Camera is electrically connected with central processing system, central processing system is electrically connected with planar light source; Detect any protruding variation the on tested surface when needs; And accurately positioning convex changes when the relative position on this plane; Planar light source is opened in central processing system control, and planar light source is launched the directional light that is parallel to tested surface, and these directional lights form an optical plane; After object enters into optical plane, the light that the sensitive surface of this object will plane of reflection light source; Because through the existence of reflection object light, can produce " hot spot " of specific wavelength at the sensitive surface of object, camera during this time begins to get involved gatherer process, " hot spot " that camera will collect is transferred to central processing system; Central processing system is at first handled the raw image data that absorbs from camera; Raw image data is that camera carries out the data that the A/D conversion produces; After we obtain view data, can extract the work of image information, all carry out the data in the viewing area of whole camera the extraction of one whole; If actual application environment more complicated; Just need carry out the Filtering Processing of software, adopt the mode that only retains main brightness of image or carrier chrominance signal, make the main information " hot spot " of image more obvious.Central processing system obtains the main coordinate parameters of " hot spot " through computing; Behind the main coordinate parameters that obtains " hot spot "; Because camera and the planar light source height is certain and relative position coordinates is certain; At this moment just formed the formed three-dimensional relative position of camera, " hot spot " and optical plane, central processing system just can be collected the coordinate information of the tested surface state of any change through mathematical computations like this.
The directional light that said planar light source is launched specific wavelength can be macroscopic visible light, also can be invisible lights such as ultraviolet ray, infrared ray.
Optical plane and tested surface height that the directional light that said planar light source is launched forms can be set by the application demand of reality.
Said camera can be CCD or CMOS camera.
Said camera is in the process of gathering " hot spot ", and the camera lens place can determine whether that needs install the filter of specific wavelength additional, come the filtering ring environmental light according to the environment for use of reality.
Said central processing system is made up of the device with logic computing function.
The present invention is based on planar light source and realize the location, method is simple, practical, can in the dark or carry out accurate localization under the various complex environment.

Embodiment
A kind of device and method based on the planar light source location; Comprise a planar light source 3, a camera 1 and a central processing unit 2 are provided; On tested surperficial 4, be installed on a planar light source 3; Camera 1 is perpendicular to planar light source 3 and be higher than planar light source 3 placements, is positioned at the region surface that needs detection with the viewing area that guarantees camera 1; Camera 1 is electrically connected with central processing system 2, central processing system 2 is electrically connected with planar light source 3; Detect tested surperficial 4 any protruding the variation when needs; And accurately positioning convex changes when the relative position on this plane; Planar light source 3 is opened in central processing system 2 controls, and planar light source 3 is launched the directional light that is parallel to tested surface, and these directional lights form an optical plane 5; After object enters into optical plane 5, the light that the sensitive surface of this object will plane of reflection light source 3; Because through the existence of reflection object light, can produce " hot spot " of specific wavelength at the sensitive surface of object, camera 1 during this time begins to get involved gatherer process, " hot spot " that camera 1 will collect is transferred to central processing system 2; Central processing system 2 is at first handled the raw image data that absorbs from camera 1; Raw image data is that camera carries out the data that the A/D conversion produces; After we obtain view data, can extract the work of image information, all carry out the extraction of one whole to the data in the whole camera viewing area 6; If actual application environment more complicated; Just need carry out the Filtering Processing of software, adopt the mode that only retains main brightness of image or carrier chrominance signal, make the main information " hot spot " of image more obvious.Central processing system 2 obtains the main coordinate parameters of " hot spot " through computing; Behind the main coordinate parameters that obtains " hot spot "; Because camera 1 and planar light source 3 are highly certain and relative position coordinates is certain; At this moment just formed camera 1, " hot spot " and optical plane 5 formed three-dimensional relative positions, central processing system just can be collected the coordinate information of the tested surface state of any change through mathematical computations like this.
The directional light that said planar light source 3 is launched specific wavelength can be macroscopic visible light, also can be invisible lights such as ultraviolet ray, infrared ray.
Optical plane 5 and tested surperficial 4 height that the directional light that said planar light source 3 is launched forms can be set by the application demand of reality.
