Embodiment Construction

[0013] Such as figure 1 As shown, a specific flow of the film source encoding method for solid-state true three-dimensional volumetric display: use the three-dimensional computer graphics software 3D Max to produce a three-dimensional model; render the three-dimensional model in the background buffer on the Win32 and OpenGL platforms, use glReadPixel The function reads a 16-bit floating-point depth value Z and three 8-bit binary color values ​​R, G, and B; then use the formula: Y=0.299*R+0.587*G+0.114*B, U=-0.169*R -0.331*G+0.5*B+128, V=0.5*R-0.419*G-0.081*B+128 convert the color value R, G, B into Y, U, V; figure 2 As shown, the color value is encoded according to the YUV encoding protocol, the 16-bit floating-point depth value is converted into a 10-bit binary code, and the Y value is shifted back four bits, Z9~Z6 is placed in Y7~Y4, and the U value is Move three digits back, Z5~Z3 to U7~U5, move the V value back three digits, Z2~Z0 to V7~V5; then determine which mode to u...

Abstract

The invention discloses a film source coding method for solid true three-dimensional volumetric display. According to the method, a virtual scene with depth information is built, a 16-bit floating-point type depth value Z of each pixel point and three unsigned 8-bit color values R, G and B are extracted, and 24-bit RGB values of all the pixel points are converted into 24-bit YUV signals; coding is conducted on YUV values and the depth values Z to generate new YUV values, then transmission and decoding are conducted on the new YUV values or coding is conducted on the YUV values and the depth values Z to generate new YUV values, and finally, the new YUV values are converted into the 24-bit RGB values to be transmitted and decoded. By means of the film source coding method for solid true three-dimensional volumetric display, the generated film source is more flexible and compatible, the sensitivity of human eyes to the brightness can be better suited when coding is conducted on the YUV signals, and the color signals are enriched, so that the displayed image is more lifelike and detailed.

Description

technical field [0001] The invention relates to the technical field of true three-dimensional stereoscopic display, in particular to a film source encoding method for solid-state true three-dimensional volumetric display. Background technique [0002] True three-dimensional stereoscopic display technology is to display images in a space with a certain physical depth, so as to provide viewers with a more realistic three-dimensional sense. True three-dimensional stereoscopic display technology has many advantages such as realistic image, full view, multi-angle, simultaneous observation by multiple people and real-time interaction. At present, the true three-dimensional display technology mainly includes two types: laser holographic display and volumetric true three-dimensional display, and the volumetric true three-dimensional display technology includes two methods: rotating volume type and solid volume type. [0003] Completely reproducing the images of the real natural spa...
