The development of optical laser fast scanning visual measurement technology and instrument optical/laser fast scanning visual measurement technology and instrument has adapted to the requirements of high-speed inspection in manufacturing. The visual measurement technology is mainly applied to the rapid measurement of geometrical dimensions and positional errors of complex curved surfaces (such as car body, mold and other three-dimensional shapes), and is widely used in online measurement and reverse engineering.
Laser scanning measuring instrument for reverse engineering The LACUS series laser line scanning measuring instrument developed by Hisense Reverse Engineering Co., Ltd. uses optical triangulation method to stratify or track the surface of the object with a laser knife, and then collects the surface to be measured by CCD. After the light knife curve, through the computer software for data processing, you can get the surface 3D data of any complex surface, the measurement accuracy can reach 0 05mm. The 3D laser scanner exhibited by Beijing Machine Tool Research Institute can realize plane scanning, rotating scanning, Two-phase scanning, hybrid scanning and other scanning methods, the line laser scanning speed can reach 1000 points / s.
Nextec's Hawk series of 3D scanning and digitizing systems use WIZ probes, with excellent optical systems, unique Beijing Machine Tool Research Institute 3D laser scanner control and image processing software, for almost all materials and finishes (including The surface of the block gauge is scanned and automatically self-calibrated, and the surface contour of the workpiece can be automatically tracked; the accuracy of the instrument can reach 10m, the accuracy of the fitting curve is 2m/100 points, the repeatability is 2m, the resolution is 1 m, and the maximum The scanning speed is 100mm/s and the data acquisition speed is 40 points/s, which can meet the requirements of high-precision fast scanning measurement.
