In the maintenance projec of Nirayama Reverberatory Furnace, we conducted the investigation using the latest optical measurement technology. Main equipment is a digital camera and a laser scanner. Use of a digital camera can reduce the time and cost of field work and improve the accuracy of information. There is also the benefit of sharing information and improving evaluation accuracy. With a laser scanner, we carried out drawing making and uneven classification from point cloud data. These data are widely used among related parties in a system using a web server.
