摘要： 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.

摘要： 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.

摘要： The present application discloses method for generating a panorama image based on a rendering engine associated with a display apparatus. The method includes determining a display model configured to be a polygon prism for a rendering engine corresponding to a panorama view of a scene. Additionally, the method includes using multiple sampling cameras associated with the rendering engine to capture multiple sample sub-images of the panorama view in respective directions towards multiple sub-planes of the polygon prism. The method further includes attaching the multiple sample sub-images to respective multiple sub-planes to form a constructed display model. Furthermore, the method includes rendering the constructed display model by the rendering engine to reconstruct a panorama image and displaying the panorama image on the display apparatus.

摘要： The present disclosure is related to an image processing method of virtual reality. The image processing method may include obtaining position information of a gaze point; performing a compression process on an original image to obtain a compressed image based on the position information of the gaze point; performing a compression process on a distorted image of the original image in an lens to obtain a compressed distorted image based on the position information of the gaze point; and performing an anti-distortion process on the compressed image to obtain an anti-distortion image based on a relationship between the compressed image and the compressed distorted image. The position information of the gaze point may be position information of a gaze point of a user's eye on an original image.
