Abstract
The invention aims to provide a viewer position detecting and prompting method for a 3D (3-Dimensional) television. A suggest of moving to the best viewing position can be provided for a viewer according to a comparison result of the detected viewer position and the best viewing position preset in a program, so that the viewer can be guaranteed to move to the best viewing position through an intuitional prompt without complex measurement and debugging work so as to obtain the best 3D video viewing experience.
Description
Technical field:
The invention belongs to the 3D TV domain, be specifically related to a kind of beholder's position probing, reminding method of the 3D of being used for TV.
Background technology:
The 3D Display Technique is at present just flourish; Product on sale is numerous on the market; To become one of mainstream technology of TV foreseeable future, but the many relative positions to beholder and display screen of prior art have strict restriction, will decline to a great extent in case depart from best viewing location display effect.Simultaneously digital video collecting device and infrared distance measurement equipment is through years of development, and performance, cost be unusual maturation and be tending towards optimum state.Combine the 3D Display Technique and can not produce excessive influence to product cost this moment with video acquisition and infrared distance measurement equipment, and can have a new approach to solve the problem of 3D display device to the strictness restriction of beholder's relative position.
Small-sized digital video collecting device and infrared emission receiving equipment are very ripe now through years of development; Volume can be controlled at very small dimensions; And cost is very cheap; Extensively be integrated in portable sets such as mobile phone, panel computer, hardware foundation be provided for it combines with the 3D Display Technique.
Summary of the invention:
The beholder's position probing and the reminding method that the purpose of this invention is to provide a kind of 3D of being used for TV; Can offer the suggestion that the beholder moves to best viewing location according to the best viewing location that detection beholder position versus is preset in the program, thereby guarantee that the beholder need not carry out complicated measurement debugging work and can obtain better 3D video-see experience with oneself moving to best viewing location through prompting directly perceived.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
(1) with video capture device as for 3D TV top center position, the infrared emission receiving equipment places the 3D TV remote controller, start starts the equipment be connected simultaneously
(2) control device of control unit (is example with FPGA) reads the vision signal of video decode plate, i.e. the vision signal of video signal processing unit, as be found to be the 3D vision signal, and the user can be through the remote-controller function beholder's position detecting function that presses switch to open.
(3) FPGA detects the signal data of video capture device; Utilize people's face detection algorithm to confirm the relative angle of beholder and display screen; The infrared emission receiving equipment that is positioned at remote controller simultaneously obtains one group of infrared ray is emitted to TV reflected back remote controller from remote controller time data; And with returning data to FPGA, calculate the relative distance of remote controller and TV by FPGA.
(4) FPGA is preset in the best viewing location information in the program according to the relative angle that obtains, range information contrast, draws data difference.
(5) FPGA is quantized to uniform units with data difference, obtains a data X, and with written forms such as " backward moving X rice forward, left, to the right, " it is shown to screen through LVDS.
(6) repeating step 3-5 overlaps in testing result and range of tolerable variance that the best viewing location that presets is presetting, and the prompting beholder finishes to best viewing location.
The invention has the beneficial effects as follows: guarantee that the beholder need not carry out complicated measurement debugging work and can obtain better 3D video-see experience with oneself moving to best viewing location through prompting directly perceived.
Description of drawings:
Accompanying drawing 1 is to be used for the beholder's position probing of 3D TV and the flow chart of reminding method.

(3) FPGA detects the signal data of video capture device; Utilize people's face detection algorithm to confirm the relative angle of beholder and display screen; The infrared emission receiving equipment that is positioned at remote controller simultaneously obtains one group of infrared ray is emitted to TV reflected back remote controller from remote controller time data; And with returning data to FPGA, calculate the relative distance of remote controller and TV by FPGA.
(4) FPGA is preset in the best viewing location information in the program according to the relative angle that obtains, range information contrast, draws data difference.
(5) FPGA is quantized to uniform units with data difference, obtains a data X, and with written forms such as " backward moving X rice forward, left, to the right, " it is shown to screen through LVDS.
(6) repeating step 3-5 overlaps in testing result and range of tolerable variance that the best viewing location that presets is presetting, and the prompting beholder finishes to best viewing location.
