New Approach in Non-Contact 3D Free Form ScanningThe need for an efficient, accurate and fast non-contact laser based metrology system has been a major challenge for the last few years. While various non-contact systems exist in the market for vision, calibration and digitizing, none has overcome the technology barriers and provided the required performance to bring efficient, fast and accurate 3D sensor to the CMM world.
To address the new challenges imposed by the 3D free form shapes, a 3D laser-based scanning sensor, combining advanced laser and vision technologies has been developed. It comprises of an adaptable laser source; a sophisticated set of optics; an advanced real time adaptive control and a two-dimensional CCD sensor. An extensive set of image processing algorithms analyzes and elaborates the high-quality data gathered.
