aq ense The Angular Calibration Tool The Angular Metric Calibration Tool of* the AQSENSE SAL3D library extracts automatically and easily calibration parameters for reconstruction of Point Clouds without distortion, from scanned objects using a camera-laser configuration rotating about an axis. \ 1 [ / / M f Features  Easy to use: Only a simple single step calibration operation required Օ Very accurate conversion 2.5D -> 3D  Totally removes perspective distorsion effects (1) Օ Average real 3D error: 50 \sm (2) 1. Perspective distortion occurs, due to distance difference from scanned object to the camera. Lens distortion can as well be corrected by using the Lens Distortion Tool. 2. Real condition, using AQSENSE Peak Detector Tool. Camera-laser angle: 30°, F.O.V. = 130mm. Sensor noise, laser speckle, depth of focus, etc... may influence the result. Benefits  More compact and cost saving, compared to linear scanner Օ Perfect for integration on a robot arm  Allows 3D scanning of wide static areas Angular Calibration using AQSENSE's calibration pattern Turbine scanned using the Angular Metric Calibration Tool Match3D Sample Code const PatternSPPoints points = {{{-30, 30}, {-10, 60}, {10, 60}, {30, 30}}, 60 }; const float initialAngle = -5.0f const float angleStep = 0.01 f sal3d::AngularMetric::Config config = sal3d::AngularMetric::calibrate(patternRangeMap, points, initialAngle, ang) // Now we use the config obtained to create a COP. sal3d::COP cop(patternRangeMap, config, initialAngle, angleStep); Angular scanner integrated on a robot arm AQSENSE S.L. | Parc Cientկfic i Tecnolgic de la UdG | 17003 Girona - Spain Tel. +34 972 183 215 | Fax. +34 972 487 487 www.aqsense.com | info@aqsense.com^^^^^^^^^^H
