Title:
SINGLE-SCREEN CIRCUMFERENTIAL-TRANSLATION BITMAP-TYPE VOLUME DISPLAY METHOD
Document Type and Number:
WIPO Patent Application WO/2019/219092
Kind Code:
A1
Abstract:
Disclosed is a single-screen circumferential-translation bitmap-type volume display method. An imaging screen which performs circumferential translation motion is provided; a two-dimensional image representing a cross section of a three-dimensional scene is displayed on the imaging screen; and bitmap information of the two-dimensional image and the display position of the two-dimensional image on the imaging screen are dynamically refreshed according to the real-time position of the imaging screen, so as to form a time-division two-dimensional image sequence having parallel images; by means of visual persistence effect, the two-dimensional image sequence is perceived and restored to a three-dimensional scene by an observer. Compared to the display method in the background art, the present invention significantly simplifies the driving mechanism and improves the duty cycle of the display space and the duty cycle of the display time under the premise of ensuring uniform voxels and achieving inertial force balance. Therefore, the present invention is particularly suitable for precise display of three-dimensional images, and has wide application prospects in the field relating to three-dimensional image display, such as industrial design, scientific research, teaching presentation, medical CT analysis, and spatial mechanism motion simulation.
