Abstract
A device for detecting the visual characteristics of a nakedness-eye stereoscopic display is provided, which comprises a nakedness-eye stereoscopic display, a sensor, a computer, a measuring rod, an X-axis guide rail and a Y-axis guide rail. The device is characterized in that the X-axis guide rail, the Y-axis guide rail and the measuring rod are connected with the sensor; and the nakedness-eye stereoscopic display, the sensor, the X-axis guide rail, the Y-axis guide rail are connected with the computer. The utility model has the advantages that (1) the CCD can simulate the actual observation condition of human eye so that the captured image is equal to the image viewed by the human eye; (2) the autogenous and xenogenous images in independent view zones are captured at the same time, simplifying the measuring process; (3) the stereoscopic degree is more compliant to the requirement for measuring the object; (4) the image processing technique is used to calculate the value of stereoscopic degree; and (5) the designed stereoscopic display effect of the nakedness-eye stereoscopic display is evaluated based on the stereoscopic degree.
Description
Technical field
The utility model relates to a kind of naked-eye stereoscopic display visual characteristic measuring appliance.
Background technology
Three-dimensional display needs a pair of actual image of watching of eyes that is equal to, promptly usually said " three-dimensional to "; Need stereo pair images is correctly delivered to people's eyes simultaneously, for naked-eye stereoscopic display, it is the separation of finishing view with the empty point-score of optics, the light of each view is separately propagated in the space in display the place ahead the back by special optical element, the light beam of wedge makes view produce converging action, formed the independent vision area that corresponds respectively to the inferior screen of right and left eyes, independent vision area spatially is the water chestnut column, the effect of stereo display depends on the correct reception of right and left eyes view, for naked-eye stereoscopic display, an if there is no pure left side, right eye independence vision area, or there be serious crosstalking mutually in the image between independent vision area, eyes will not receive corresponding stereo pair images, and human brain just can't carry out stereoscopic fusion.
Estimate and use the method for measuring, compare according to the objective data and the canonical parameter value of instrument test, thus the quality of judgement stereo display effect.The method of quantitative measurment is the important evidence that research field and meter inspection department implement evaluation.
Summary of the invention
The purpose of this utility model provides a kind of naked-eye stereoscopic display visual characteristic measuring appliance, measures and characterize the visual characteristic of naked-eye stereoscopic display with three-dimensional degree.
The utility model is achieved like this, it comprises naked-eye stereoscopic display, sensor, computing machine, sounding rod, X-axis guide rail and Y-axis guide rail, it is characterized in that X-axis guide rail, Y-axis guide rail are connected sensor with sounding rod, naked-eye stereoscopic display connects sensor, and sensor connects computing machine.
The utility model has the advantages that: the actual observation situation that (1) ccd video camera (sensor) can the emulation human eye, the image of shooting is equal to the actual image of watching of eyes; (2) take the image of genus certainly of independent vision area simultaneously and he belongs to image, simplified measuring process.The error of also having avoided the measuring process factor to bring; (3) " three-dimensional degree " realization purpose of coincidence measurement object is more distinguished mutually with " contrast " notion of regular display easily; (4) use image processing method to calculate three-dimensional metric, gained is objective reality as a result; (5) naked-eye stereoscopic display of the enough three-dimensional degree judge designs of energy has or not the stereo display effect; (6) can go out good zone of three-dimensional degree and bad zone at the viewing area build-in test of naked-eye stereoscopic display; (7) with " three-dimensional degree " as evaluating, help setting up an objective standard parameter, thus to measuring without the naked-eye stereoscopic display of type and identifying.
Description of drawings
Fig. 1 is a principle of work block scheme of the present utility model;
Naked-eye stereoscopic display 2, inferior screen test pattern 3, sensor 4, image pick-up card 5, computing machine 6, visual characteristic measurement result 7, X-axis guide rail 8, sounding rod 9, Y-axis guide rail in the drawings, 1,
Embodiment
As shown in Figure 1, the utility model comprises naked-eye stereoscopic display 1, sensor 3, computing machine 5, sounding rod 8, X-axis guide rail 7 and Y-axis guide rail 9, it is characterized in that X-axis guide rail 7, Y-axis guide rail 9 and sounding rod 8 are connected sensor 3, naked-eye stereoscopic display 1 connects sensor 3, sensor 3 connects computing machine 5, comes from the image of naked-eye stereoscopic display, enters sensor through inferior screen test pattern 2, enter computing machine through image pick-up card 4 again, computing machine demonstrates visual characteristic measurement result 6.
Each test is from the left side in naked-eye stereoscopic display the place ahead, also be the maximum subtended angle that detent mechanism can be determined, be about 30～45 degree, use the plane rotating shaft mechanism of polar coordinate system, at different visual angle alignment sensors, the solid of inferior screen test picture about collection.The pitch of measuring is chosen to be 1 degree (or 1 millimeter), also can be converted into planimetric coordinates very easily and represent.According to image processing method, the image of genus certainly that can obtain different visual angles belongs to brightness of image with him, calculates corresponding three-dimensional degree.
