Measuring Method of Bearing Size Based on Improved Hough Transform of Circle Geometric Characteristics

Lixiong Gong

Abstract


Proposed a method of acquiring bearing center, which is improved Hough transform for circle geometric characteristics because of shortcomings of Traditional Hough transform. The method is based on feature that the perpendicular bisector line passed center of circle by means of gradient search to find circle, then compute bearing inner and outer diameter. Finally, bearing size measurement scheme is designed to apply to bearing geometric size measuring and verified the correctness of measuring method.

Keywords


Bearing, Hough transform, Image processing, Geometric characteristics, Histogram.
