Problems solved by technology

[0003] The larger the range of 3D viewing distance and the larger the 3D viewing angle, the more convenient, freer and more comfortable it is for people to watch stereoscopic images. Limited by this distance and angle, it is impossible to watch stereoscopic images conveniently, freely and comfortably
[0004] Therefore, realizing the measurement of these two parameters is an important way and method to judge the quality of 3D display devices, but there is currently a lack of effective measurement methods for these two parameters

Embodiment Construction

[0057] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0058] see figure 1 and figure 2 , are schematic diagrams of modules of the first embodiment and the second embodiment of the measurement system for 3D viewing distance and viewing angle according to the present invention, respectively. Such as figure 1 and figure 2 As shown, the measurement systems for 3D viewing distance and viewing angle of the first embodiment and the second embodiment both include: a 3D display device 10 , a receiving device 20 and a main control device 30 .

[0059] Wherein, the 3D display device 10 is configured to play the first color test image and the second color test image in a side-by-side mode. For example, a red test card is used for the first color test image, and a green test card is used for the second color...

Abstract

The invention relates to a 3D (three dimension) visual distance and visual angle measuring system and a method therefor. The 3D visual distance and visual angle measuring system comprises 3D display equipment, a receiving device and a master control device, the 3D display equipment is used for displaying a first color testing image and a second color testing image in a side-by-side mode, the receiving device comprises a first imaging device and a second imaging device which are arranged abreast, and horizontal distance between the first imaging device and the second imaging device is adjustable. The master control device is used for receiving images acquired by the first imaging device and the second imaging device. By adjusting receiving distance and rotation angle between the 3D displaying equipment and the receiving device, the range of the receiving distance and the range of the rotation angle, meeting the visual condition, are measured and used as the 3D visual distance and the 3D visual angle respectively. The testing images displayed by the 3D display equipment are received by the receiving device and analyzed by the master control device. By adjusting the receiving distance and the rotation angle between the 3D display equipment and the receiving device, the visual distance and the visual angle which meet the visual condition are measured, and important parameters of the 3D display equipment can be measured effectively.

Description

technical field [0001] The present invention relates to the field of three-dimensional image technology, and more specifically, relates to a measurement system and method for 3D viewing distance and viewing angle. Background technique [0002] The current 3D (three-dimensional) display, 3D imaging technology and equipment are developing rapidly, and both display technology and imaging technology focus on "stereoscopic sense (that is, the depth information of the foreground, middle ground, and background that people feel when watching 3D images) "And develop. The more obvious and comfortable the depth information that people feel, the stronger the sense of freedom in viewing, that is, the less restricted, which means the better the stereoscopic effect. This degree of visibility, comfort, and strength of freedom are affected by two important parameters / performances - 3D viewing distance and 3D viewing angle. [0003] The larger the range of 3D viewing distance and the larger...
