Embodiment Construction

[0035] The realization method of realistic 3D digital portrait uses multiple portrait data acquisition devices to shoot the subject at multiple points and angles at the same time, and obtains the three-dimensional data and color data of the structure and shape of different parts of the character's surface at a specific moment.

[0036] see figure 1 The method for collecting character data by the portrait collection device of the present invention is described. Such as figure 1 As shown, five 3D scanners are respectively placed on the vertices of a square cone with a bottom surface, and the five 3D scanners are connected to a USB HUB, and the USB HUB is connected to a computer; five digital cameras are also placed on the bottom surface respectively. It is each apex of a square cone, five digital cameras are connected to another USB HUB, and the USB HUB is connected to a computer; the position of the subject is set at the center of the bottom square.

[0037] see figure 2 De...

Abstract

The invention relates to a method for realizing a realistic three-dimensional digital portrait. In the method, multiple portrait data acquisition devices surrounding the subject are simultaneously photographed in all directions at multiple points and angles, and all three-dimensional data on the surface of the subject at a specific moment are captured at one time. and color data, process and reconstruct the captured 3D data and color data by computer to obtain the complete 3D model data and color data of the character, and finally combine the complete 3D model data and color data The spatial position and color information are accurately synthesized to generate a color digital model of a realistic 3D digital portrait, and the color digital model is imported into the model browsing software, and the realistic 3D digital portrait is rotated, zoomed in, and zoomed out.

Description

technical field [0001] The invention relates to a method for realizing a digital portrait, in particular to a method for realizing a realistic three-dimensional digital portrait. Background technique [0002] At present, the application technology of portrait digital imaging is the method of texture processing on the 3D model obtained by modeling the figure picture. The 3D model formed by this method has low precision and cannot correctly represent the morphological structure of the figure. The cycle of making a digital portrait is long. low efficiency. Contents of the invention [0003] The object of the present invention is to provide a method for realizing a realistic three-dimensional digital portrait with a short production period and accurate shape. Multiple portrait acquisition devices are used to collect the color three-dimensional data of different parts of the figure at one time, and a complete high-precision color three-dimensional image is generated in the comp...
