Abstract: A three-dimensional reconstruction method, comprising: performing slide calculation on an acquired current image frame to obtain to-be-processed windows; performing point feature extraction and line feature extraction on the to-be-processed windows, and determining corresponding features in each to-be-processed window; performing iterative quadtree splitting for circles on each target to-be-processed window to obtain circular regions of interest corresponding to each target to-be-processed window; performing feature screening on features in the target circular regions of interest to obtain target features corresponding to each target circular region of interest; and performing three-dimensional reconstruction corresponding to the current image frame by using the target features. By introducing line features in the feature extraction stage of three-dimensional reconstruction, the line segment features in the three-dimensional reconstruction scenes can be better perceived, and the reconstruction efficiency of simple regular three-dimensional models can be accelerated.

Abstract: A near-eye display device and an eye tracking system for the near-eye display device are provided. The eye tracking system includes a processor, a control analysis device, an LED illuminating device, a DMD display device and an IR camera. The processor outputs a video signal corresponding to a video displayed on the near-eye display device to the control analysis device. The control analysis device generates an LED synchronization signal and a corresponding subfield display signal. The LED illuminating device drives an LED to emit light, and transmits the light emitted from the LED into the DMD display device. The DMD display device reflects the light into a lens to form an image, and projects the image onto an eye. The IR camera captures an eye image. The control analysis device acquires the eye image and analyzes the eye image to obtain gaze point information.
