Abstract

The invention relates to an integrated method for the measurement and reconstruction of a three-dimensional model and a system thereof. The method comprises the following steps: 1) obtaining the three-dimensional coordinates of surface markers of an object sample; 2) interactively constructing the three-dimensional model based on the three-dimensional coordinates. The method integrates measurement and reconstruction as a whole and simplifies an inverse reconstruction process of the three-dimensional model to benefit for the rapid inverse reconstruction of the object sample and to avoid complex secondary measurement (supplement measurement) and guarantee the integrity of the reconstructed model. Color and texture information of surfaces of the samples can be reconstructed, data volume of the reconstructed model is small and is suitable for being used under network environment. Repeated measure can be effectively avoided to improve the efficiency of measurement and reconstruction. A measuring apparatus has the advantages of small volume, light weight and convenient motion. The design intent of the model can be fully considered in the measurement and reconstruction process in favor of measurement planning.

Description

technical field

[0001] The invention relates to an integrated method and system for measuring and reconstructing a three-dimensional model. Background technique

[0002] The technique of generating a 3D model of a product from a physical sample is usually called reverse design or reverse reconstruction. see figure 1 , reverse reconstruction usually includes two main steps: 1) measurement of physical samples; 2) reconstruction of 3D model. The process of using various measuring equipment to obtain the surface data of the physical sample is called the measurement of the physical sample; the process of using the measurement data as input to generate a three-dimensional model acceptable to the computer-aided design (CAD) system is called the reconstruction of the three-dimensional model.

[0003] Inverse reconstruction is widely used in manufacturing, medicine, geographic information system, virtual reality and other fields. The goal of reverse reconstruction in the manufactu...
