Problems solved by technology

[0013] The characteristics (disadvantages) of the existing three-dimensional cameras: 1. The optical path system is complex and bulky, and cannot be used portablely like ordinary cameras, and can only be taken at designated locations; 2. The cost is high, and the market price is more than 150,000 yuan. Difficult to popularize and apply

Embodiment Construction

[0026] Other objects, features and advantages of the present invention can be better understood by describing in detail the embodiments of the three-dimensional portrait photography system of the present invention in conjunction with the accompanying drawings.

[0027] see figure 1 Describe the three-dimensional portrait photography system of the present invention. like figure 1 As shown, the three-dimensional portrait photographing system consists of a set of photographing equipment 1 , a computer 2 connected with the photographing equipment 1 , and a laser engraving machine 3 connected with the computer 2 . The photographing device 1 may be a digital camera, or may be an ordinary optical camera plus a scanning device. When shooting a three-dimensional portrait, the camera device 1 first takes a front and side photo of the portrait. If a digital camera is used, the digital file, that is, the photo can be directly transmitted to the computer 2. If an ordinary optical camera ...

Abstract

The present invention provides a three-dimensional portrait photography system and its implementation method. The system uses an ordinary camera to take photos of the front and side of portraits, uses a computer vision algorithm to obtain a three-dimensional geometric model of the head, and according to the projection relationship between the photo and the geometric model, the Photos are mapped onto the 3D geometric model as a texture to obtain a photorealistic 3D portrait model; then use the spatial halftone method to spatially modulate the continuous-tone texture-mapped grayscale image and "print" it inside the artificial crystal through a laser engraving machine "Produce a binary image that is similar to the original 3D image in terms of visual observation effect, forming a realistic 3D entity avatar.

Description

technical field [0001] The invention relates to a photographing system, in particular to a system for realizing three-dimensional portrait photography and output by using a common camera and computer software and a method for realizing the same. Background technique [0002] In real life, objects exist in the form of three-dimensional geometric entities. The traditional two-dimensional plane photos create a visual three-dimensional sense of space through chiaroscuro and perspective relationship, and cannot produce a fascinating natural three-dimensional sense. The spatial modeling of 3D images is close to the prototype. It not only has the characteristics of height, width, and depth of 3D spatial geometry, but also has real and realistic surface texture information. It can change the sense of realism that cannot be given by plane photos, and can give people a friendly and comfortable feeling. Realistic feeling. The observer can view the three-dimensional image from any ang...
