Display apparatus, display system and three-dimensional display method

Abstract

The invention discloses a display apparatus, a display system and a three-dimensional display method. The display apparatus comprise a display panel and at least one camera device arranged around thedisplay panel, wherein each camera device comprises at least two depth cameras, and the range of depth of field of any depth camera is not completely overlapped with the ranges of depth of field of the other depth cameras; the display panel is used for displaying three-dimensional images after image information shot by the camera devices is processed. As the camera device comprises at least two depth cameras with different ranges of depth of field, the shooting precision of these depth cameras within the respective ranges of depth of field is high, after the ranges of depth of field of the depth cameras are overlapped, the range of depth of field is wider than that of any depth camera, therefore clear imaging within the range of depth of field can be expanded. After the ranges of depth offield of the depth cameras are set according to demands, the demand of close-range manipulation and interaction can be adapted to.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device, a display system and a three-dimensional display method. Background technique [0002] With the rapid development of 3D technology in the field of display, display products based on 3D technology are becoming more and more diverse. At present, devices that allow the operator to interact with the 3D space model in the display are more and more popular with users. 3D space interaction can be Bring the operator a more vivid three-dimensional interactive experience that is different from plane interaction. The current three-dimensional space interaction is based on three-dimensional space positioning technology. The most common spatial positioning technologies are dual-vision technology, structured light technology, and Time of Flight (TOF for short) ranging technology. The above three spatial positioning technologies all use cameras, and generally use fi...

AI Technical Summary

Problems solved by technology

The above three spatial positioning technologies all use cameras, and generally use fixed-focus cameras, which makes the current spatial positioning have two problems: First, due to the use of fixed-focus cameras, its detection accuracy is relatively low in the depth of field. Accurate, once the depth of field is exceeded, the detection accuracy will drop rapidly; second, the current space positioning device has a limited operating space, and the blind area for close-range operation is relatively large
