1, 3D laser scanner
The development of optoelectronic technology and computer technology has led to the rapid development of non-contact three-dimensional free-form surface measurement technology based on optical principle equipment and computer image processing and other working principle equipment. Many new types of measurement methods are continuously produced. With high precision, high speed, no damage, non-contact and easy to implement automated measurement under computer control, it has become an important way and development direction of 3D surface measurement. However, handheld 3D laser scanners play a very important role in contactless scanning.
2, camera type 3D scanner
In the non-contact 3D scanner, there is also a very important one is the 3D white light scanner. Nowadays, there are many 3D blue light scanners. For example, our Hualang 3D 5 million blue light scanner has been made in the industrial field. Significant achievement, the working process is similar to the photographic process, scanning a measuring object at a time when scanning an object, fast and concise, hence the name. The camera-type 3D scanning adopts the surface light technology, and the scanning speed is very fast. Generally, it can acquire more than one million measuring points in a few seconds. Based on the multi-viewing measurement data splicing, the 360-degree scanning of the object can be completed, which is a three-dimensional scanning. And a good assistant for industrial design and industrial testing.
3, three coordinate measuring machine
Contact measurement, also known as mechanical measurement, is one of the most widely used digital methods for free-form surface 3D models. The coordinate measuring machine is a typical representative of the contact measuring instrument. It is based on precision machinery and integrates advanced technologies such as electronic technology, computer technology, optical technology and numerical control technology. According to the different way of measuring the movement mode of the sensor and the generation mode of the trigger signal, the contact measurement method is generally divided into two types: single-point trigger type and continuous scan type.
