Abstract

Feature recognition has been an active research area in the past two decades. While many techniques have been developed, most of them are limited to the detection offeatures that are of regular shapes. Examples include holes, slots, pockets and steps that are commonly used in engineeringparts. Thispaper reports our investigation on a method that is able to detect free-form features. A template matching approach is used where the template represents the shape of the free-from feature to be detected Thefeature recognition method works on a two-dimensional parametric space which represents all possible configurations of the template. A match between the template and the objectfrom which thefeatures are to be detected corresponds to a match-curve in the parametric space. Feature recognition is achieved byfirst searching the rough location of the match-curve,followed by searching a precise location of a point on the match-curve. A program has been implemented to veriJj, the feasibility of the approach, and examples are given to demonstrate the major steps in the method The use ofthe method in computer graphics applications such as shape blending is demonstrated. The application of the technique in industrial applications such as injection mould design is also discussed. © 2000 IEEE.
