Problems solved by technology

[0002] In virtual reality VR (Virtual Reality) equipment, in order to allow users to have a real sense of immersion visually, the virtual reality equipment must cover the visual range of the human eye as much as possible, which requires a specific spherical surface to be installed in the virtual reality equipment. Radian magnifying lens, but when the traditional image is projected into the human eye through the magnifying lens, the image is distorted, so the image needs to be pre-distorted

Embodiment Construction

[0065] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0066] At present, there are many ways to research the distortion correction of VR equipment in the industry. For example, from the aspect of optical path design, the theoretical distortion parameters can be output directly through the corresponding software, and then manually fine-tuned from the application side. This method is time-consuming and laborious, and the effect is not good.

[0067] To solve this problem, refer to figure 1 , an embodiment of the present application provides a method for measuring distortion parameters, which is used to measure the distortion parameters of a display device. The display device includes a display screen and a lens located on the light-emitting side of the display screen. The measurement me...

Abstract

This application provides a method, device and system for distortion parameter measurement, which is used to measure the distortion parameters of the display device.Determine the distortion parameters of the display device according to the second corner point that meets the preset conditions and the first angle point corresponding to the initial image on the first distortion image.It is easier, and this measurement method can accurately calculate the distortion parameters of the display equipment on the display device, improve the measurement efficiency, and then improve the accuracy of distortion correction.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method, device and system for measuring distortion parameters. Background technique [0002] In virtual reality VR (Virtual Reality) equipment, in order to allow users to have a real sense of immersion visually, the virtual reality equipment must cover the visual range of the human eye as much as possible, which requires a specific spherical surface to be installed in the virtual reality equipment. Radian magnifying lens, but when the traditional image is projected into the human eye through the magnifying lens, the image is distorted, so the image needs to be pre-distorted. Contents of the invention [0003] The invention provides a method, device and system for measuring distortion parameters, so as to measure the distortion parameters of a display device more easily. [0004] In order to solve the above problems, the present invention discloses a method for measu...
