Abstract

A system for the simultaneous acquisition of multiple images using laser scanning techniques is reported. It is intended for inspection tasks that require a variety of different image qualities to be highlighted. The particular application this system has been designed for is the grading of sheep pelts prior to sale for processing into leather. The primary aim of the application is the presentation of consistent and relevant information to an operator, allowing better grading decisions to be made. To achieve this, three different types of images are generated and presented. These are; reflection, transmission and fluorescence, all being acquired simultaneously using a scanned laser spot. Techniques used to collect, concentrate and detect the laser and fluorescent light are outlined and images presented. Ultimately, it is hoped that the machine will automatically detect defects and classify pelts. To this end high speed computing hardware is incorporated into the system design.
