Metric Calibration Tool SAL3D Tools The AQSENSE SAL3D Metric Calibration Tool provides a straightforward, easy procdure for obtaining true XYZ metric coordinates from 2.5D rangemap data coming from any standard laser triangulation system. Features:  Extremely easy to use 镕 Use of our specific calibration pattern design  Very Accurate conversion 2.5D -> 3D Օ Totally removes perspective distortion effects (1)  Average theoretical 3D error: 1e-7fjtm (2) Օ Average real 3D error: 50 jim (3) 1 Perspective introduces object's size distortion with the distance to the camera. This tool does not correct lens distortion, such as radial distortion. ^f^^^# #^ 2 Evaluated with synthetic data. Only the mathematical method is evaluated here 3 Real situation, using AQSENSE Peak Detector Tool, at 30° camera-laser angle, F.O.V. = 130mm. Sensornoise, laser speckle, depth of focus, etc... influence this result.
