Problems solved by technology

[0005] However, the scanning accuracy of the existing technology is generally not high, and the integrity is not enough. Second, it is easy to cause the scanned point cloud data to be imported into the software to reconstruct the model later. The stitching accuracy is not high, and the characteristics of the object cannot be reflected after the reverse modeling. Cause reverse modeling to fail

Abstract

The invention discloses a reverse deconstruction method of a product based on three-dimensional scanning, comprising the following steps: S1, placing the product on a rotary table; S2, determining a scanning standard of the product and fixing a plurality of mark points on the surface of the product; 3, performing following operations that that rotary table rotate through a set angle from rest every predetermine time while scanning the surface of the product with a depth scanner to obtain a point cloud data set compose of the surface data of the product, wherein the set angle is a center anglebetween a mark point currently facing the depth scanner and a next mark point; 4, importing that point cloud data set into the Imageware software for point cloud processing; S5: importing The data processed by S3 into the three-dimensional software, and carrying out reverse modeling to obtain the three-dimensional model of the product. The invention can deconstruct the structure of the existing product, quickly and accurately obtain a three-dimensional design model of the product, and ensures the accuracy of the three-dimensional design model.

Description

technical field [0001] The invention relates to the field of product reverse design, in particular to a product reverse deconstruction method based on three-dimensional scanning. Background technique [0002] Reverse engineering (also known as reverse technology) is a product design technology reproduction process, that is, reverse analysis and research on a target product, so as to deduce and obtain the processing flow, organizational structure, functional characteristics and technical specifications of the product, etc. design elements to produce products that are similar in function but not identical. [0003] Reverse engineering originated from hardware analysis in the commercial and military fields. Its main purpose is to deduce the design principle of the product directly from the analysis of the finished product when the necessary production information cannot be easily obtained. Reverse engineering technology has been applied to product duplication, imitation, impr...
