What are the advantages of 3D scanning technology?Release time: 2015-06-02 09:46
3D scanning technology uses many advantages. When 3D scanning technology can be used to measure the fine parts of some objects, ordinary tools cannot be measured. 3D scanning technology has exerted its absolute advantages. Medical and other industries are widely used. This article Standard Group (Hong Kong) Co., Ltd. focuses on introducing the advantages of 3D scanning technology.
Optical three-dimensional scanner is a technical means to achieve the comparison with the real object by acquiring the mold surface curved surface data. By detecting the irregularity of the object through comparison, the surface measurement method is divided into two types: contact and non-contact. The three-dimensional coordinate measuring instrument has high measurement accuracy, but extremely low efficiency. The non-contact measurement equipment is mainly based on the three-dimensional digital imaging principle of optical three-dimensional scanners, such as structured light measurement and triangular facet measurement methods for modeling.
The measurement accuracy of 3D scanning instruments is the key to obtaining high-quality free-form surfaces. Therefore, how to effectively evaluate the measurement capability of the scanner is of great significance. Non-contact measurement equipment is mainly based on optical method of three-dimensional digital imaging technology, such as laser triangulation, structured light projection method. Germany has established the accuracy test standards for non-contact three-dimensional measurement, and was drafted by the German Engineers Association in 2002 VDI / VDE 2634-2 optical measurement system testing standards were issued;
This standard introduces a detection method to evaluate the accuracy of point-by-point detection optical 3D measurement and imaging systems and a method of detecting the accuracy of optical 3D measurement and imaging systems based on area scanning. In this standard, a rectangular parallelepiped with a diffusely reflecting surface is used to evaluate plane measurement errors in 7 different directions in space. The literature gives a method to confirm the measurement accuracy of three-dimensional vision sensors using a coordinate measuring machine. The National Institute of Metrology (NPL) has developed a true free-form standard. "
3D scanning products are gradually welcomed by domestic enterprises, especially small and medium-sized industrial enterprises due to their high modeling efficiency and economical price. China is becoming a global manufacturing center with a large number of small and medium-sized industrial enterprises. Therefore, the future market for 3D scanning products is very broad.
