The method thereof comprises: 1) getting synchronous image information of the indicator and background through said two lens sets; 2) the acquired image information is transmitted to the image sensor through the optical array behind the lens sets; 3) the image processor processes the image information to determine the location of the indicator.
Description
[technical field]
The present invention relates to a kind of screen positioning device and localization method, particularly relates to a kind of screen positioning device and localization method that utilizes the Optical Fiber Transmission location.
[background technology]
Existing interactive intelligent electronic whiteboard is to utilize two or more CCD or CMOS camera to obtain target image continuously, and the image that each camera is obtained carries out the synthetic processing of image then, as depicted in figs. 1 and 2.This scenario-frame is comparatively complicated, needs a plurality of cameras to work simultaneously, and needs to solve the asynchronous problem of image between the different cameral, and its algorithm is also comparatively complicated; Simultaneously, under identical technical conditions, the pixel that its positioning accuracy and orientation range will directly be subjected to existing camera limits.
Therefore, need provide a kind of and realize the function of pickup image, and location Calculation is simple, the screen positioning device that can make full use of the pixel resource of existing camera with the location with simple structure.
[summary of the invention]
The purpose of this invention is to provide screen positioning device and localization method that a kind of simple in structure, location Calculation is simplified.
To achieve these goals, the present invention adopts following technical scheme:
A kind of screen positioning device is provided, it comprises at least two optical lens, fiber array, and image processor, these at least two optical lens are installed in screen periphery or corner location and have overlapped fov, one end of fiber array connects image processor, and the other end is divided into and the connection corresponding with optical lens of at least two arrays.
Each optical lens is imaged on background in the whole screen overlay zone and indicating device on the fiber array of each optical lens back.
The end of fiber array in the optical lens back is that linear array is arranged or the face battle array is arranged, and the centre position of alignment optical camera lens, to receive the background that is centered around around the screen and the light signal of indicating device simultaneously.Handle for the ease of a large amount of light signal that utilizes image processor that optical fiber is collected, all multi-channel optical fibres by the orderly arrangement on the physical structure after, be arranged in a face battle array structure at image processor one end, also the light signal that receives has been carried out rearranging of locus in the lump in the time of the optical signal transmission that will receive from optical lens, at last multipath light signal while concentration of transmissions is arrived same image processor, made full use of the pixel of image processor, solve image processors such as utilizing CCD and CMOS and directly received the problem that the pixel deficiency occurs, simplified the structure of this positioner simultaneously, obtain view data with simple structure, realize the location.
This localization method comprises the steps:
(1), obtains the synchronous images information of indicating device and background by at least two optical lens;
(2), the fiber array of the image information of being obtained behind optical lens transfers to image processor;
(3), image processor carries out computing to image information, determines indicator post.
Compared with prior art, the present invention has following beneficial effect:
Screen positioning device of the present invention adopts two or more optical lens to obtain the light signal of image, and can reconfigure the characteristics of arrangement by optical fiber itself, light intensity signal in the different light paths of several roads is reconfigured and concentrate to be transferred on the same image processor and handle, realize synchronized positioning with simple structure; And having made full use of the pixel of image processor, optical fiber arrangements also is not subjected to the restriction of image processor pixel, can be fit to the more location of large-screen; This localization method can directly utilize the image information Synchronous Processing of different angles triangle relation to calculate and locate, and can simplify greatly on algorithm; In addition, this screen positioning device is adapted at charged workplace and uses and anti-electromagnetic interference, also can use under wet environment and unaffected.

[embodiment]
Please refer to Fig. 3, it is the embodiment schematic diagram of screen positioning device of the present invention, this screen positioning device comprises three optical lens with overlapped fov 1 that are installed in three angles of screen, after multi-channel optical fibre 2 is ordered in optical lens 1 respectively, making linear array arrangement or face battle array arranges, and the centre position of alignment optical camera lens 1, to receive the signal that the background signal be centered around around the screen and indicating device block simultaneously, being optical lens 1 is imaged on the background in the whole screen overlay zone and indicating device on the fiber array 2 behind each optical lens 1, multi-channel optical fibre 2 behind the receiving optical signals is again through arranging in order, be arranged in face battle array structure at CCD or cmos image processor 3 one ends, also the light signal that receives has been carried out rearranging of locus in the lump in the time of the optical signal transmission that will receive from camera lens 1, at last multipath light signal while concentration of transmissions is arrived same image processor 3, carry out synchronized positioning and calculate, just can determine the position of indicating device in screen.
The linear array that this multi-channel optical fibre 2 can be made 1 * n is arranged or the face battle array of m * n is arranged, and gathers the synchronous images data by optical lens 1, and with image data transmission to same image processor 3, synthesize to handle and calculate, with the position of the indicating device of definite images acquired.
As shown in Figure 4, this localization method comprises the steps:
(1), obtains the synchronous images information of indicating device and background by at least two optical lens;
(2), the fiber array of the image information of being obtained behind optical lens transfers to image processor;
(3), image processor carries out computing to image information, determines indicator post.
Fiber array behind this optical lens is arranged in face battle array structure at image processor one end.Two-way that this image processor is next with the fiber array transmission or the image information more than the two-way are compiled, and by calculating to determine indicator post.
The above is preferred embodiment of the present invention only, and protection scope of the present invention is not limited thereto, and those of skill in the art are any to be included within protection range of the present invention based on non-material change on the technical solution of the present invention.
