Abstract

This paper describes on-going research into machine vision systems based on the line-scan or linear array type cameras. Such devices have been used successfully in the production line environment, as the inherent movement within the manufacturing process can be utilized for image production. However, applications such as these have traditionally involved using the line-scan device in a purely two-dimensional role. Initial research was carried out to extend such 2-D arrangements into a 3-D system, retaining the lateral motion of the object with respect to the camera. The resulting stereoscopic camera allowed three-dimensional coordinate data to be extracted from a moving object volume (workspace). The most recent work has involved rotating line-scan systems in relation to a static scene. This allows images to be produced with fields of view varying in both size and position in the rotation. Due to the nature of the movement the images can be complex dependent on the size of the field of view selected. Benefits of obtaining images in this fashion include `all-round' observation, variable resolution in the movement axis and a calibrated volume that can be moved to observe any point in a 360 degree arc.
