Abstract
This paper presents a method for rapidly generating crude, appearance-based edge models consisting of a set of planes. The appearance of each plane is modeled using a set of keyframes containing a list of edgels. These models are generated from a short video sequence with a few annotated frames indicating the location of the object of interest. The data requires 3–5 min to collect using a handheld device instrumented with a camera. The models produced are used with an existing edge tracking algorithm modified to select the appropriate edge keyframe and detect occlusion. A framestore is also created containing several views of the object represented as sets of point features. The framestore is used to provide an initial, rough pose estimate for initializing contour tracking. The presented system is used to create an augmented reality application to guide a user through a machine tool setup and a printer maintenance task. The models are shown to be an accurate representation of the object. Additionally, the performance of various aspects of the model making and tracking algorithms are evaluated.
