A: The principle of photo-based 3D scanner
Photographing is a new generation of scanners for the industrial field. Compared with traditional laser scanners and three-coordinate measuring systems, the measuring speed is increased by several tens of times. byTherefore, by means of photographing, the dead angle of the scan is relatively small, so the measurement accuracy is greatly improved. It uses visible light to project specific grating fringes toMeasuring the working surface, taking pictures of the grating interference fringes with two high-resolution CCD digital cameras, using optical photo localization technology and grating measurement principle,A complete point cloud of complex work surfaces is available in a very short time. Its unique flow design and automatic stitching technology for point cloud of different viewing angles make scanning unnecessaryFor machine tool drives, scanning ranges up to 30M, while scanning large workpieces becomes efficient, easy and easy. Its high quality perfect scanning point cloud can be used for steamProduct development, reverse engineering, rapid prototyping, quality control in the vehicle manufacturing industry.
Two: the advantages and disadvantages of camera-type 3D scanners and laser scanners
Laser scanner:
Advantages: The technology is mature, no need to stick the mark, the operation is convenient and fast, and it can be moved.
Disadvantages: It is scanned by points and lines. The single format is small and the data accuracy is relatively low.
Photographic 3D scanner:
Advantages: The new product is a mainstream product with small scanning dead angle, fast scanning speed and high precision.
Disadvantages: need to spray powder stickers, work is large, not mobile.
Three: Features of the camera-type 3D scanner:
Fast
2. High precision
3. Easy to operate
