Abstract: The present application discloses method for real-time processing image data based on a rendering engine. The method includes sampling a first set of data in a first pixel arrangement to be displayed as an image in a display screen with pixels in a second pixel arrangement. The method further includes creating a first model mapped with the first set of data to generate a second set of data and a second model mapped with the first set of data to generate a third set of data. Additionally, the method further includes rendering the second set of data using a first shader to output a fourth set of data and rendering the third set of data using a second shader to output a fifth set of data. Furthermore, the method includes superimposing the fourth set of data over the fifth set of data to display a sixth set of data.

Abstract: The present disclosure provides a method and device for measuring a distortion parameter of a visual reality device and a measuring system. The method includes: obtaining an anti-distortion grid image according to a first distortion coefficient; obtaining a grid image of the anti-distortion grid image at a preset viewpoint after the anti-distortion grid image passes through a to-be-measured optical component of the visual reality device; determining a distortion type of the grid image after passing through the to-be-measured optical component; adjusting the first distortion coefficient according to the distortion type of the grid image, thereby obtaining an adjusted first distortion coefficient and then reducing distortion of the grid image; repeating the above steps until the distortion of the grid image is less than or equal to a distortion threshold. The adjusted first distortion coefficient when the distortion of the grid image is less than or equal to the distortion threshold, is taken as a distortion coefficient of the to-be-measured optical component.
