The principle of 3D scanner
Three-dimensional non-contact measurement technology using structured light technology, phase measurement technology, and computer vision technology. The use of this three-dimensional measurement technology makes it possible to perform photographic measurement of objects. The so-called photographic measurement is similar to that of a camera taking pictures of objects in the field of view. What the measuring instrument obtains is the three-dimensional digital information of the object.
Different from traditional 3D scanners, our company's 3D scanner can continuously measure a three-dimensional surface. During measurement, the grating (spot) device projects several structured rays (spots) of specific codes onto the object to be measured, forming a certain amount of light. Two (or more) cameras at the included angle simultaneously capture the corresponding images, then perform phase and decoding calculations on the images, and use matching technology and triangulation principle to solve the public field of view of two (more) industrial cameras The 3D coordinates of the pixels on the inner surface of the object.
