3D Human Sweep Scanning Technology Future Development Trend Analysis

3D scanning is one of the 3D measurement techniques. Under the past, the means of obtaining the size of the item size data can only be limited by the traditional cyber ruler, or not easily moving the three-time bed. Today, technology has been projected through the probe or optical lens, and the 3D data can be achieved according to the coordinate, the purpose of measurement can be achieved.

There are currently dozens of 3D scanning technologies in the market, including two mainstreams in contact and non-contact, contact measuring techniques to return to the computer through probe, non- Contact measuring technology, that is, our commonly known 3D scan, through the optical lens, with a change in the change of thunder or different light source, the reflection of the object is analyzed to become a number of information.

Taking Industrial Grade 3D Scanner ATOS as an example, the principle of the device adopts Structure Light Scanner, which is projected from the light source to the surface of the object to the surface of the object, and obtains digital information Wide applications, such as automotive manufacturing, precision instruments, technology products, aviation equipment, energy equipment, art culture, etc.

3D scanning future development trends:

3D scanning technology is dominated by non-contact laser, photographic, white light, which can have a high Measurement accuracy, suitable for performing relative dimensions measurement and quality management; fast, accuracy, appropriate accuracy, and can scan three-dimensional items to obtain a large number of point cloud data, reconstructed with profile surface, and after scanning, read out data, usually This part is called the pre-treatment project.

After obtaining the data of the product, the point data processing is performed by the refusal engineering software, after the alignment of the division, the ethnic group, the point line and the entity error, and then restructive surface model, generate CAD data, Furthermore, RP Part can be produced to confirm the mechanism and geometry, or NC machining and mold manufacturing, these are subsequent processing parts.

The three-dimensional scanning technique has been produced, and many scanning principle has been developed, and the non-contact method has been developed from three-dimensional data, and the non-contact method is invested in demand. The application is the most widely used, and the laser triangle method is also divided into different ways of point light source and line light source depending on the light source. The tissue method of the data different from the different ways is different. The method based on the contact-based continuous scanning measurement is also partially applied due to the relatively high precision, but from the speed and price indicators are different than non-contact.

In the field of human machine engineering, virtual reality, clothing CAD, digital three-dimensional scanner, the advantages of exclusive lead in the same type of China, digitizing the human structure, and quickly fasting the human body multi-angle Shoot, automatically realize point cloud data splicing, automatically generate digital images and point cloud data.With the further development of research and development, various new three-dimensional scanner technology will continue to appear and are applied to commercial systems, and existing three-dimensional scanner technology will continue to be improved to meet the needs of manufacturing.
