Abstract: A control method for an imaging system is provided. The imaging system includes a display device and a dimming lens disposed on a display side of the display device. The dimming lens is capable of moving toward or away from the display apparatus to adjust an object distance from the display device to the dimming lens. The control method includes: determining the object distance when the dimming lens moves to a set position; according to the object distance, determining an image distance from a virtual image, generated by a display image of the display device through the dimming lens, to the dimming lens; and according to the determined image distance and a correlation between the image distance and a resolution of the display image, determining a resolution corresponding to the determined image distance, and controlling the display device to display the display image at the determined resolution.

Abstract: A method of dynamically displaying a three-dimensional image object in a volumetric display apparatus is provided. The method includes rotating a display plate about an axis to display a volumetric three-dimensional image; displaying a first three-dimensional image of a first three-dimensional image object according to first coordinates in a first image coordinate system in the volumetric display region; sensing a position or a movement of an external real-world object within a sensing zone; and displaying a second three-dimensional image of a second three-dimensional image object according to second coordinates in a second image coordinate system in the volumetric display region. The second three-dimensional image object is obtained by reorienting the first three-dimensional image object from an initial orientation to a target orientation; and the reorientation is correlated with a position or the movement of the external real-world object.

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.
