Abstract

A device for evaluation and test of a nakedness-eye stereoscopic display is provided, which is characterized in that a microcomputer is connected with an image collection card, an X-axis guide rail, and a Y-axis guide rail; the image collection card is connected with a sensor; the sensor is connected with the X-axis guide rail, the Y-axis guide rail, a polar coordinate guide lever and a sub-screen test picture; and the sub-screen test picture is connected with the nakedness-eye stereoscopic display. The utility model has the advantages that the measurement and system operation are easily completed; the sensor is positioned by the coordinate mechanism before display, so as to measure the stereoscopic degree in any visual fields; and the sensor can be positioned in any position suitable for observation in the three-dimensional space.

Description

Naked-eye stereoscopic display evaluation and testing tool

Technical field

The utility model relates to a kind of naked-eye stereoscopic display evaluation and testing tool.

Background technology

Naked-eye stereoscopic display is a kind of brand-new stereo display type, and the evaluation of its technical quality does not also have corresponding industry or national standard at present.The technical quality evaluation of naked-eye stereoscopic display can be set up standard with canonical parameter and corresponding test method, thereby can carry out objective appraisal to the display effect of naked-eye stereoscopic display.

Naked-eye stereoscopic display has used flat-panel display device as image-display units, and therefore, the image displaying quality index of inferior screen can be with reference to the measurement and the evaluation method of flat-panel monitor of the same type.And naked-eye stereoscopic display has the singularity of himself, and it need show one or more pairs of stereo pair images simultaneously in the viewing area, and these images have changed their light ray propagation direction and formed distinctive independent vision area through the effect of optical element.Can know from the principle of stereo display technique, relief power depends on the correct reception of stereo pair images, be that independent vision area has from attribute and exclusiveness, in this independent vision area, only allow to see the image on the corresponding inferior screen and can not see image on other inferior screen, but because the principle and the physical property of display device have determined the difficulty that desirable optical propagation realizes in reality, the independent vision area on the pure meaning can only be a kind of ideal.

Summary of the invention

The purpose of this utility model provides a kind of naked-eye stereoscopic display evaluation and testing tool, is used for quality test and standard evaluation to naked-eye stereoscopic display.

The utility model is achieved like this, it comprises sensor, microcomputer, X-axis guide rail and Y-axis guide rail, it is characterized in that, microcomputer connects image pick-up card, image acquisition card connection sensor, sensor connects X-axis guide rail, Y-axis guide rail, polar coordinates guide pole and inferior screen test pattern and shows, inferior screen test pattern connects naked-eye stereoscopic display.

The utility model has the advantages that: (1) measuring operation system is convenient, uses coordinate mechanism alignment sensor before display, then can measure the three-dimensional degree between any viewing area; (2) can be in the three dimensions that is fit to watch the optional position alignment sensor.
