Dip and Strike Uncertainty

[chris-traxler]

Dip and strike measurements are carried out by drawing a polyline onto the surface to which a plane is fitted. The plane fitting algorithm produces a rough error estimation in real-time, which should be used as live feedback while drawing the polyline. This can be done by a colour indicator with traffic light hues.

For an uncertainty visualization after fitting, the more accurate PCA method described by Quinn and Ehlmann should be implemented. See Fig. 2B in their paper for a possible visualisation method in 3D. Task separation:

• Live feedback indicator for plane fitting accuracy
• Error estimation based on PCA method form Quinn and Ehlmann
• Uncertainty visualization in 3D
