Problems solved by technology

[0003] However, most of these new products are in the experimental or scientific research stage. On the one hand, it is because of the high price of the hardware (the relatively high bandwidth of data transmission and the huge number of LEDs driven by the display make the configuration and quantity of the MCU relatively high. ) and the instability of the mechanical structure (the high-speed rotating huge display screen is as powerful as the propeller of the aircraft, overcoming various dynamic balance, safety measures and heat dissipation problems caused by the long-term rotation of the motor in a sealed environment); The bigger reason is the singleness of film source selection or acquisition method (limited to a single field or a model with specific mathematical parameters), which severely limits its scope of application

Embodiment

[0077] In this embodiment, a doll (for example, the mascot "Haibao") is used as the reproduction object, and the resolution of the volume-scanning true 3D display used is Nh*Nv of 192*256. The three-dimensional display process of the doll is as follows:

[0078] First, use the data acquisition module to acquire the Cartesian 3D coordinate data of the object to be reproduced and its corresponding 24-bit RGB true color data (x, y, z, r, g, b).

[0079] Use 3DMAX to build a 3D image of Haibao, render it, and export the ASE file of the project. You only need to use the program to read the number of grid vertices from it to create a double-layer structure object k, and set the coordinates of the grid vertices (x, y, z) Read into the structure respectively; then read the grid texture vertex coordinates (X, Y) to find the RGB24-bit true color in the corresponding map according to the coordinates and store them in the structure, respectively: k[i].x, k[i ].y, k[i].z, k[i].r, k[i].g, ...

Abstract

The invention discloses a displaying method of a stereo-scanning 3D (three-dimensional) display. The displaying method comprises the following steps of: acquiring Cartesian coordinate data and color data of a 3D image by virtue of a data acquisition module; storing the acquired Cartesian coordinate data and color data into a data storage module in an (x, y, z, r, g, b) format; carrying out normalization processing on the Cartesian coordinate data through a data processing module; mapping the normalized Cartesian coordinate data to a cylindrical coordinate system through the data processing module, then mapping the normalized Cartesian coordinate data to a display screen coordinate system, and storing data of the cylindrical coordinate system and data of the display screen coordinate system into the data storage module; and transmitting the data of the display screen coordinate system to the display by virtue of the data processing module. Compared with the conventional technology, the stereo-scanning 3D display disclosed by the invention has various advantages of lifelike image, full visuality, multiple angle, simultaneous multi-user observation, real-time interaction and the like, and provides the method for acquiring the three picture source data, thereby expanding the application field of the stereo-scanning 3D display.

Description

technical field [0001] The invention belongs to the fields of computer vision and three-dimensional display, and in particular relates to a display method of a volume scanning three-dimensional display. Background technique [0002] More than 80% of human beings obtain all kinds of information that are important to the survival of the body come from vision. With the development of electronic computer technology, various and complicated display devices have emerged as the times require. After the birth of the Avatar 3D movie, it announced the advent of the era of 3D display. Volumetric 3D true color display is a new product that has emerged in recent years. Many advantages. Different from the line scan monitors on the market, it uses dynamic volume scan technology to truly realize true three-dimensional display. [0003] However, most of these new products are in the experimental or scientific research stage. On the one hand, because of the high price of the hardware (the r...
