The three-dimensional scanner is divided into a laser-type three-dimensional scanner and a photo-type three-dimensional scanner. Today, the focus is on a photo-type three-dimensional scanner. The scanning principle is similar to that of a camera, and the product is born to solve the industrial design and industrial application requirements.
The advantage of the camera type is high precision and high speed scanning. The measurement range can be adjusted freely according to the needs. Currently, the advanced structure non-contact photogrammetry principle is adopted. The basic principle of structured light 3D scanner is: a composite three-dimensional non-contact measurement technology combining phase measurement technology, computer vision technology and structured light technology. Through this measurement principle, it is possible to take photographs of an object. Photogrammetry is similar to taking a picture of an object by a camera. The difference is that the camera takes a two-dimensional image of the object, and the developed measuring instrument is a three-dimensional image of the object. information. Unlike traditional 3D scanners, the scanner can measure one side at the same time. During the measurement, the grating projection device projects a plurality of specific coded structured light onto the object to be tested, and the two cameras at a certain angle synchronously obtain the corresponding image, then perform phase calculation and decoding on the image, and use the triangle measurement principle and match. The technique calculates the three-dimensional coordinates of the pixels in the common view of the two cameras. The camera-type 3D scanner can move the workpiece position freely for on-site measurement, and can adjust any angle for all-round measurement. It can also perform block measurement on large workpieces. The measurement data can be automatically combined, which is also very suitable for workpieces with large spans. Such as cars and home appliances, sculptures, etc.). Small to small parts scan to the overall measurement of the body can be perfect, cost-effective. Mainly used in the industrial design industry, to achieve 'one machine in hand, design worry-free' for customers!
