Where can I learn 3D coordinate measurement in Changzhou?

Zhitai’s service center in Changzhou is in Xinbei District, over Taihu Road. There are dozens of service centers across the country to provide services nearby, and the headquarters is in Nanjing.

Three-dimensional measurement, as the name suggests, is an all-round measurement of the object being measured to determine the three-dimensional coordinate measurement data of the object being measured. Its measurement principle is divided into four aspects: ranging, angular displacement, scanning, and orientation. The instruments developed based on the principles of three-dimensional technology include three measuring instruments: photographic (structured light) three-dimensional scanner, laser three-dimensional scanner and three-dimensional coordinate measuring machine. Three-dimensional measurement can be defined as "a detector that can move in three directions and can move on three mutually perpendicular guide rails. The detector transmits signals in contact or non-contact ways. A three-axis displacement measurement system The data processor or computer calculates the coordinates (X, Y, Z) of each point of the workpiece and the measurement of various functions." The measurement functions of three-dimensional measurement should include dimensional accuracy, positioning accuracy, geometric accuracy and contour accuracy, etc. Measuring high-precision geometric parts and measuring complex-shaped mechanical parts in machinery, automobiles, aviation, military industry, furniture, tool prototypes, etc.

Application fields of three-dimensional measurement technology:

Three-dimensional laser scanning technology continues to develop and become increasingly mature, and three-dimensional scanning equipment is gradually commercialized. The huge advantage of three-dimensional laser scanners is that they can quickly Scan the measured object and directly obtain high-precision scanning point cloud data without a reflective prism. This allows efficient 3D modeling and virtual reproduction of the real world. Therefore, it has become one of the hot spots of current research and has been widely used in the fields of digital protection of cultural relics, civil engineering, industrial surveying, natural disaster investigation, digital urban terrain visualization, urban and rural planning and other fields.
