Abstract

The invention discloses a hardware implementation method for a floating-point type multi-view naked-eye three-dimensional synthetic image, and belongs to the field of 3D (three-dimensional) display. Firstly, equivalent transformation is performed for a pixel synthesis formula, original floating-point type variable complementation is transformed into constant complementation, and further constant complementation is transformed into arithmetic easily implemented by hardware by a comparator. Complexity of floating-point type multi-view naked-eye 3D image synthesis hardware is decreased, variable complementation not easily implemented by the hardware is transformed into arithmetic, and arithmetic speed is increased on the basis of ensuring calculation result accuracy. By changing corresponding parameters, the hardware implementation method is applicable to different types of grating or cylindrical lens structures, and compatible with integer and floating-point type parallax image synthesis methods.

Description

【Technical field】 [0001] The invention belongs to the technical field of video image processing, and in particular relates to a hardware implementation method for multi-viewpoint naked-eye stereoscopic composite images. 【Background technique】 [0002] Glasses-free 3D display technology utilizes the visual physiological characteristics of the human eye. When images with slight parallax enter the left and right eyes of a person, the fusion of the brain can bring the viewer a three-dimensional visual experience. At present, most of the mainstream glasses-free 3D display technologies on the market are based on cylindrical lens technology. Due to the existence of optical refraction in the panel, there will be a splitting effect, and the parallax images will enter the left and right eyes of the person respectively at a suitable viewing distance and viewing angle to produce stereoscopic perception. [0003] The multi-view glasses-free 3D display device selectively selects required...
