In the Advanced Settings menu, you can adopt DAVID to your special requirements. For beginners and “usual scanning”, it is recommended to leave all Advanced Settings unchanged.
In DAVID, all 3d coordinates are given with respect to the same coordinate system “WORLD”:
The coordinates of all calibration markers given in Calibpoints.dat
The coordinates that are calculated during scanning and later saved in an OBJ file
All coordinates that you can specify here
LeftBackgroundPlane and RightBackgroundPlane
DAVID needs to know where your background planes (“wings”) are in order to calculate the correct laser line pose during scanning. Here you can specify those planes, each by a point P and a normal vector N.
P (px, py, pz) can be any point that is part of the plane (Standard: 0,0,0)
N (nx, ny, nz) is a normal vector that is perpendicular to the plane. Its length is irrelevant. The direction is important: It must point towards the side of the plane where the camera is.
LeftMirrorPlane and RightMirrorPlane
If your setup contains mirrors that allow the camera to see the rear side of the object, you can specify the position of those planes here. It is used for the function “Reflect on Mirror Planes” in the right-click menu of DAVID-Shapefusion.
GrabReferenceImageOnStart: The Reference Image is grabber when you click 'Start'. Afterwards, DAVID only looks at differences to that image, this makes it easier to detect the laser line. If your image is perfectly black (except for the laser line), you can choose 'false'. Then the laser does not have to be switched off in the moment when you click 'Start'.
For demonstration purposes only. Simulates a series of mouse clicks to let DAVID operate alone (only Laserscanner part).
