Method and device for measuring time delay difference between left and right eye images in stereoscopic display

Abstract

The invention provides a measurement method and device for three-dimensionally displaying a left and right eye image time delay difference. The method comprises the following steps of S1, setting a left-eye image sequence and a right-eye image sequence having a frame-by-frame horizontal displacement characteristic, wherein the frame frequencies of the two image sequences are the same; and in the left and right eye image sequences, defining one left eye image and one right eye image having the same frame number as an image pair; S2, displaying a test signal sequence on a three-dimensional display device, wherein the bright and dark areas of two groups of test units with the same display position in the image pair are superimposed and displayed; and S3, on the three-dimensional display device, observing that one pair of light and dark area change points of the test unit is superposed with the horizontal coordinate positions of the dark and light area change points, recording the serial number of the test unit, according to the predefinition of the test unit, combining the frame frequencies of a left-eye image and a right-eye image to obtain a frame-level time delay difference.

Description

technical field [0001] The invention relates to the field of stereoscopic display measurement, in particular to a method and device for measuring the time delay difference between left and right eye images of stereoscopic display. Background technique [0002] Stereoscopic display is what we usually call 3D display. In 3D display, the picture is three-dimensional and realistic. The image is no longer limited to the screen plane, but the out-screen and in-screen visual effects are added, so that the audience has an immersive feeling. Stereoscopic display has been used in many fields, such as television, movies, games, medical imaging, engineering display, etc., but because stereoscopic display is transmitted and displayed in separate channels for left and right images in many systems, due to the performance differences of electronic devices and the length of transmission channels Factors such as unequal or software settings will cause the left and right eye images to appear a...

Stereoscopic display has been used in many fields, such as television, movies, games, medical imaging, engineering display, etc., but because stereoscopic display is transmitted and displayed in separate channels for left and right images in many systems, due to the performance differences of electronic devices and the length of transmission channels Factors such as unequal or software settings will cause the left and right eye images to appear asynchronous on the display end, that is, there is a certain delay difference between the left and right eye images in the stereoscopic display, which will affect the user's stereoscopic display experience

In the prior art, the time delay difference between the left and right eye images is displayed stereoscopically by using a photoelectric conversion probe plus an oscilloscope. The advantage of this method is that the principle is simple, but the disadvantage is that it requires equipment for auxiliary testing and it is difficult to determine the left and right channels on the oscilloscope. The chronological relationship of images is not conducive to daily monitoring or engineering application
