Problems solved by technology
However, the white line may disappear due to some factors, and then it cannot be decoded correctly
At the same time, for the problem that the color band is easily interfered by the object itself, the two patent applications are solved by reducing the number of color levels. In addition to not completely solving the problem, the resolution is also sacrificed, and the materials that can be applied are even less pitiful.

Embodiment Construction
[0062] The present invention discloses a three-dimensional color information extraction method and its device. First, please refer to figure 1 , mainly adding at least one laser locator 101 to the imaging device 102 to judge the distance of the object whose image is to be captured. The two laser points can be adjusted so that they overlap at a distance of L mm from the lens of the imaging device 102. If the L value is small, the imaging range is small; if the L value is large, the imaging range is large. The imaging device 102 can be a digital camera or a color CCD camera, and the set-top flashlight 103 can flash a common light source (white light) 106 when taking an image for the first time, and simultaneously switch to another sample light source by a switching module 104 for the second time. For secondary image capturing, it may include a sample projector 105 (which may be a flashlight) and a sample slide 107, so as to project a sample light source onto the object.

The invention discloses an equipment and method of taking tridimensional color information. The invention includes the following procedures: take the chartlet image and the template image of an object by a ordinary light source and by a template light source separately, and the template light source is permutated and combinated by the tone scale of more than 3 kinds of color; analyze the distribution of the color of the object through the chartlet image; calculate the position of the color strip of the template light source in the template image through scene change detection; judge the color of the template light source that is corresponded to the template image; correct the image of the image color corresponding to the color of the template light source, thereby gain the exterior geometric information of the object; calculate the tridimensional data of the object; and obtain the tridimensional module of the object on the basis of the distribution of color, the superficial makings and the tridimensional data. The template is restricted in its distribution position and color permutation. In the condition of high resolution, it is possible to get rid of the problem of the color interference of the object, and the limit of the kinds of the material is lower.
Description
technical field [0001] The present invention relates to a three-dimensional color information extraction method and its device, which are applied to high-resolution three-dimensional model imaging, and in particular to a three-dimensional color information encoding method that uses more than three color levels to improve resolution and maintain a certain degree of reliability. Color information extraction method and device thereof. Background technique [0002] Generally speaking, there are many ways to capture a 3D image of a 3D model. For example, the 3D model can be placed in a box, and the overall appearance can be scanned with a laser, and then the 3D image can be completed with color capture; however, , such a method is not only expensive but also time-consuming, and the practicability is not great. In addition, there is a more common way, that is, the so-called color structured light source. Its method is to project a color band or a color block combination pattern (...
