Abstract

The present invention relates to a method and system for generating a three-dimensional surface image using multi-energy X-ray imaging and an optical image and, more particularly, to a method and system for generating a three-dimensional surface image using multi-energy X-ray imaging and an optical image, which comprises: reconstructing an X-ray tomographic image in which the contrast of a soft tissue including the skin of a subject is enhanced, using two or more pieces of multi-energy X-ray transmission data; calculating a three-dimensional surface model for the subject; and further generating a three-dimensional surface image of the subject by combining optical image information including color information and the like for the subject.

Description

technical field [0001] The present invention relates to a stereoscopic image generation method and system using multiple-energy X-ray imaging and optical images, more specifically, to a method of using more than two multiple-energy X-ray transmission data to reconstruct and improve the The X-ray tomographic image of the contrast (constrast) of the soft tissue inside, and calculate the three-dimensional surface model of the subject, and then combine the optical image information including the color information of the subject to generate the image of the subject Stereoscopic image generation method and system using multiple energy X-ray imaging and optical imagery. Background technique [0002] Recently, in order to plan the optimal surgical method for various operations such as plastic surgery, or to predict the surgical effect in advance, or to follow-up the surgical results, a method such as figure 1 As shown in the device, the device simultaneously acquires the patient's ...

Problems solved by technology

[0006] However, in this case, in order to generate a three-dimensional surface model, it is necessary to add an additional laser scanning device that is not used in the conventional X-ray device, and then use the laser scanning device to scan various laser patterns (for example, line pattern pattern) is irradiated on the object to be shot, and is photographed by a camera to collect the position information of the laser pattern, and then the three-dimensional coordinates of the surface of the object to be shot are calculated by using the three-dimensional geometric relationship between the laser and the camera, Therefore, to generate a three-dimensional surface model of the subject, there will be a problem that the production cost will be increased in order to constitute the above-mentioned system, and the inspection time for laser scanning will be increased.

Furthermore, this method needs to irradiate laser light to the subject (for example, a human face), so there is also a problem that the person under examination may feel uncomfortable.
