Abstract
A 3-D laser scanner system developed by the National Research Council of Canada, and implemented by Hymarc Engineering Ltd. as the HYSCAN-60 is described. The scanner provides the museum field with an accurate, high-speed, and non-contact method of capturing three-dimensional surface data from objects for basic documentation and research, and for the fabrication of replicas or supports for objects of complex shape using numerically controlled (NC) machining. The operation and design of the laser scanner are described. Applications of the system to a range of artifacts and natural science specimens having varying color, texture, and reflectivity were tested. The system has applications in the recording of living subjects including the human face for the purpose of fabricating mannequins for display. Interpretation of the range data is facilitated by the use of an interactive graphics system which also provides various editing functions. An integral part of the system is a software package which generates the co-ordinates to drive an NC milling machine, and an accurate replica of a North Pacific Coast stone mask was produced in this way. -- AATA
