[0042] see figure 1 , the first embodiment of the method of the present invention, a distortion correction real-time visual debugging method, comprising:

[0043] S1. Obtain the resolution of the VR headset and the resolution of the tested display;

[0044] VR head-mounted display: By adding a lens to a small rectangular display, and then looking at the display through the lens, a larger field of view can be obtained. The proximity of the lens to the user's eyes can greatly increase the user's field of view, but this comes at a price: the image will appear distorted and distorted. The larger the field of view, the greater the image distortion will be. "Pincushion" distortion.

[0045] S2. Generate an anti-distortion curve of the lens on the display; use the anti-distortion curve to adjust the correction parameters of each pixel in the test pattern, and save the qualified correction parameters to form an anti-distortion table.

[0046] In this method, if Figure 1a As shown...

[0073] The third embodiment of the method of the present invention is a method for real-time visual debugging of distortion correction. The steps are the same as those in Embodiment 1, except that:

[0074] There are many formulas for generating and displaying curve points, such as (Bezier curve, B-spline curve), and the B-spline curve tool can be used in this method;

Abstract

The invention provides a method of distortion correction real-time visual debugging, being applied to a VR (Virtual Reality) head display lens. The method of distortion correction real-time visual debugging includes the steps: S1, acquiring the resolution of the VR head display and the resolution of a tested display; and S2, generating an inverse distortion curve of the lens on the display, adjusting the rectification parameter of each pixel in the test pattern through the inverse distortion curve, saving the qualified rectification parameters and forming an inverse distortion table. The invention also discloses an apparatus and system of distortion correction real-time visual debugging. The method, apparatus and system of distortion correction real-time visual debugging can quickly debugthe lens inverse distortion table of the VR head display.

Description

technical field [0001] The invention relates to the field of VR display, in particular to a method, device and system for real-time visual debugging of distortion correction. Background technique [0002] VR (Virtual Reality, or virtual reality, referred to as VR) industry is an emerging industry. Compared with other electronic terminal products, the maturity of the industry is still far behind that of mobile phones and other products. [0003] Since the VR display is at a relatively short distance from the human eye, most VR uses optical lenses to change the focal length, but at the same time it also brings distortion and dispersion of the displayed image. At present, lens manufacturers in the industry perform distortion prediction based on lens parameters Judgment, generate anti-distortion rendering parameters, and let the headset manufacturer preset and call in the software. Due to the technical strength of lens manufacturers and the accuracy of equipment, most lens manu...
