Embodiment
[0016] Such as figure 1 As shown, a color 3D optical scanning method that can handle transparent and specular materials, including the following steps:
[0017] (1) Paste reusable markers for objects with strong surface specular reflection or strong transparency;
[0018] (2) Under the positioning of the reusable marker points, complete the three-dimensional scanning and automatic stitching of the object. At this time, just use the reusable marker points to complete the splicing of the positions of the objects at various angles, and aim at For each position, a color picture with elements of internal and external orientation is collected;
[0019] (3) Use a contrast enhancer to spray the part of the object where the point cloud cannot be collected, and then erase the contrast enhancer covering the reusable marker points;
[0020] (4) Scan the object again. This scan does not need to collect color pictures, but directly extracts the point cloud, and uses the reusable marker po...

The invention belongs to the non-contact optical scanning technique field and relates to a color three-dimensional optical scanning method capable of processing transparent and highlight materials. The color three-dimensional optical scanning method is characterized by comprising the following steps that: (1) reusable mark points are bonded on an object which is intensive in surface mirror reflection or has high transparency; (2) under the positioning of the reusable mark points, the three-dimensional scanning and automatic splicing of the object are completed; (3) a contrast aid is sprayed on portions of the object, the point cloud of the portions of the object cannot be acquired, the contrast aid covering the reusable mark points is wiped out; (4) the object is scanned again, point cloud is extracted directly, and splicing is performed by using the reusable mark points, and complete scanning is performed; and (5) any conventional processing flows such as grid surface encapsulation, grid surface hole filling, smoothing and simplification are completed, a model is repaired to be complete as far as possible. The color three-dimensional optical scanning method of the invention can process the color data collection of the transparent and highlight materials with convenience and quickness. The application of the color three-dimensional optical scanning method can be expanded.
Description
technical field [0001] The invention relates to the technical field of non-contact optical scanning, in particular to a color three-dimensional optical scanning method capable of processing transparent and high-gloss materials. Background technique [0002] 3D optical scanning technology is a technology used to detect and analyze the shape (geometric structure) and appearance data of objects or environments in the real world; the collected data is often used for 3D reconstruction calculations to create realistic images in the virtual world. A digital model of an object. These models have quite a wide range of uses, such as industrial design, flaw detection, reverse engineering, robot guidance, etc. With the rise of Industry 4.0, 3D printing and VR, the requirements for 3D scanning technology are getting higher and higher, but traditional industrial 3D scanners can only capture point clouds with spatial location information, and cannot automatically form color models of obje...
