PURPOSE: To improve data processing speed and measurement accuracy by using line sensors.
CONSTITUTION: A dolly 11 for putting and transporting a measuring object 1 and a plurality of line sensors 15 are arranged in the plane perpendicular to the moving direction of the dolly 11. Laser radiators 13 to irradiate laser lights spreading in sheat shape along the moving direction to the measuring location and an illuminator 14 are provided. Each detection signal from line sensors 15 for detecting the reflection light from the edge position of the measuring object 1 and line sensors 15 for detecting the sheet shape laser reflection light are input to an operator provided to obtain the angle in sight of the reflection light from each measuring location and position coordinates of the measuring location based on the positions of each line sensor 15 and each laser radiator 13 and the irradiation angles of laser lights from each laser radiator 13.
