STRAIGHT LINE DETECTION FOR AUTOMATED MEASUREMENT IN IMAGE SCENES

E. Reetz, A. Schlegel, P. Werner, G. Linß

Abstract

When dealing with point cloud data retrieved from optical coordinate measurement machines, a spline filter scale space method as proposed in [1] is applied to contour decomposition problems for automated measurement of geometric primitives/features. The object contour will be split into a more simple structure, using the spline filter scale space to detect corner regions along the contour. This article explains an approach to increase the segmentation results for straight line segments, based on point cloud data only.
