In a production process of rail vehicles, several panels such as a ceiling panel and side panels are assembled by fusion welding. The welding heat causes the assembled vehicles to be slightly distorted. In the next interior fitting process of the rail vehicle production stage, a huge number of parts must be fitted, such as air conditioning units and frame bars for straps, etc. It is very difficult for those parts to be fixed into the railway vehicles since the bolt holes are not in a right position because of the welding heat. So it is of very importanceto measure shapes of the panels and the bolt holes after the welding process. In this study, we have developed a new type of laser coordinate measuring machine with a laser distancemeter and two Galvani-mirrors. In experiments a rafter hanging on a stage was measured and its measuring accuracy was discussed.
