Introduction

RMS dense point cloud 3D optical measuring system uses the most advanced multi-frequency heterodyne phase-shifting measurement technology ,has achieved the technical level abroad of 2007,.Compared with the traditional method of Gray Code plus phase shifting,its accuracy is higher,the single measurement range is larger(from 150mm to 3 meters ),and the anti-jamming ability is increased,almost unaffected by the shading on the workpiece surface .So the workpiece generally need not be sprayed with special reagent coating,even the workpiece surface with sharply wavy changes can also be measured.

Technical Principe

The measurement process is as follows:grating projection equipment projects pieces of multi-frequency gratings onto the target object,then two cameras set in a certain angle capture the image synchronously.Afterwards,the image is decoded the 3-D coordinates of the pixels in the two cammon field of view simultaneously.

Applications

Reverse Design:getting the surface point cloud data of workpiece quickly and creating three-dimensional digital model,achieving the purpose of rapid products design.

Product Detection:It can be used in production line quality control and shape and position detection,especially for complex surface detection.IT can also detect castings,forgings,stamping parts,dies,injection molded parts,wood products and other objects.

Other Application:cultural relics scanning and three-dimensional display,orthodontics,plastic surgery and maxillofacial surgery.
