OTLines: A novel line-detection algorithm without the interference of smooth curves

作者:

Highlights:

• We proposed an orientation transformation(OT) algorithm in this paper.

• OT maps the points in each edge chain into an orientation space and detects corners.

• With OT, the circular arcs are mapped to a series of oblique lines.

• After OT, line segments and arcs can be detected simultaneously by using PCA method.

• The proposed algorithm can avoid taking a smooth curve as many straight segments.
