Laser scanning is a technology that began to be used in the mid-1990s. This is another major breakthrough in detection and mapping technology. It uses high-speed laser scanning to provide fast coordinate data. Like most people, most people only fundamentally know the internal information of the individual. His mass communication may bring another revolution to the stadium. GPS is a good example. It can quickly and accurately collect 3D cloud models, and requires antique buildings to collect data and information files. Just like GPS, it plays an important role in promoting the protection of ancient buildings.
The characteristics of laser scanning technology are fast, non-contact, real-time, dynamic, active, density, precision, digitization and automation. With the help of high-speed laser scanning technology, the surface of the object can be reached quickly. They can use the huge mass and high-resolution 3D coordinate data to quickly collect information about the movement of the earth, and provide a new technology to quickly generate a three-dimensional object model of the object. The Laser pointer has all the characteristics of real-time, dynamic, active, high-density, high-precision, digitization, automation, and fast scanning. In the traditional measurement method, the timing of each point is 2 to 5 seconds. More importantly, its application and expansion will promote the further revolution of GPS and other high-tech. It takes a few minutes to measure the position of a certain point. These speeds have exceeded the requirements that the birth of 3D laser scanners has changed this situation. The initial measurement speed was 1000 points per second, which shocked the measurement community. The maximum speed of the heartbeat scanner reaches 500 points, and the scanning speed of the super radium can reach 1.2 million points per second. It must be necessary, three-dimensional laser scanners, such as ancient wind, manufacturing rockets, royal roads and other complex and fearless objects are described in detail. Decision makers believe that the wide application of dimensional laser scanner technology in the engineering field makes dimensional laser scanners from the principle of "laser realization" (including pulsers and phase lasers) attract a lot of attention from researchers.
