1. 5 Scanning using the DAVID Laserscanner software Position the camera so that the following conditions are satisfied e The camera is positioned more or less towards the centre of the calibration panels approx 45 and is pointed more or less level into the scene e All 6 ring shaped calibration markers are fully within view of the camera some will of course be covered by the object At least some of the 64 other points should also be within view e The camera must not be able to see past the calibration panels The panels fill the complete area of the camera image e The object is visible in the centre of the frame as large as possible and will usually therefore be covering most of the calibration points 10 Once you have placed the camera in its final position adjust the focus control to get the sharpest possible image of the object s surface You may use the automatic checkbox to find the best setting but this must be turned off after adjusting the focus Remove the object temporarily from the scene to afford the camera a clear view of the calibration points Make sure when doing this that you do not move the camera or the calibration panels Adjust the camera brightness to a very high level preferably using the Exposure control under Ad vanced also turning up Brightness and Contrast under Device Settings may help so that the came ra image is extremely bright possibly even white and all the cal2.
