What are the current 3D scanning technologies?

3D scanning technology will play a revolutionary role in application upgrading in five industries:

1, in the field of urban and architectural surveying. Three-dimensional building model can be obtained by surveying and mapping with three-dimensional laser scanner, and the quality of building engineering can be monitored at the same time. For example, when an enterprise accepts a new building, it scans the building to get an accurate and detailed three-dimensional model, so as to complete the quality monitoring of the building through calculation or comparison.

2. The field of topographic mapping. Compared with traditional surveying and mapping methods, 3D laser scanning has great advantages in the form of results. For example, three-dimensional and two-dimensional data can be obtained simultaneously through one measurement. In addition, for the mining industry, the improvement of the efficiency of 3D laser scanners reduces the working hours of operators in harsh environments.

3. The field of industrial manufacturing. First of all, the 3D laser scanning system can provide a true 3D and full-size data model for factory reconstruction, thus speeding up the design progress and obtaining the best design scheme for enterprises.

Secondly, in the installation and production of some large-scale industrial equipment, the 3D laser scanner can help to complete the collection of basic data in the early stage of design, and after the processing of large-scale parts is completed, the dimensions can also be scanned and checked. For example, Invertex, an Israeli fashion technology startup, recently announced the launch of 3D scanning software for feet, aiming at solving the problem of different experiences when customers buy footwear products in physical stores and online.

In addition, this technology can also improve the safety of related industries. For example, in the field of power equipment, it is difficult to collect complete basic data information by traditional measurement methods because of the complex structure and dangerous working environment of substations and transmission systems. Through the three-dimensional laser scanner, comprehensive data acquisition can be realized in a short time.

4. Service industry. For example, Nokian, a Finnish tire manufacturer, announced its SnapSkan service in June+February, 5438 last year-using a full 3D scanner to check the tire wear of users, even when the car is driving. Its service function is: when the vehicle passes through the scanner shaped like a speed bump, the laser will automatically scan the tire tread, and then measure the depth of its grain. At the same time, the camera will shoot and intercept the license plate number. After testing, the driver can apply for a tire report form, and the report form and license plate number will be sent to the applicant by SMS.

Some experts also said that the development of 3D scanning technology has also greatly promoted the development of 3D lidar. For example, 3D lidar for vehicles combines 3D laser scanning with inertial measurement equipment to detect cloud data of points by emitting laser beams. Especially for driverless cars, the improvement of this technology will undoubtedly have a revolutionary impact on the industry.

In addition, many fitness clubs around the world have introduced 3D body scanning technology, so that members can fully understand their physical condition and fitness effect. The full-automatic human body scanner can scan a complete three-dimensional image of human body and measure various key health-related values of users, including body mass index (BMI), body composition (such as the proportion of main chemical components such as lipid, water and protein) and body fat composition. Their application in life service industry has been welcomed and recommended by many users.

5. Medical field. Huang Wenhua, Dean of School of Basic Medicine of Southern Medical University, said: With the help of 3D printing technology, medical care is bringing great changes to the medical field. For example, using 3D scanning technology and 3D printing technology to make personal customized medical protective gear can perfectly fit human bones and muscles.

In addition, airborne 3D scanning technology can also reach dangerous areas that are difficult for people to reach, such as mine disasters, earthquakes and other sudden disasters, and can accurately judge the movement trend of dangerous sources through 3D scanning, which is conducive to further actions of rescue and search and rescue, and has far-reaching significance for safety and military industry.

Generally speaking, the technological upgrading of 3D scanning technology has brought great potential for innovation and change to related industries, especially manufacturing and service industries, brought great changes to intelligent manufacturing, and brought unimaginable personalization and convenient services to people's lives, which will become an important technological driving force to promote industrial innovation in the next step.
