PROBLEM TO BE SOLVED: To measure a shape and velocity, and the like, of a moving object without incurring cost and manpower for the measurement. SOLUTION: Distance measuring data are obtained from a first laser distance measuring device for irradiating a surface parallel to the ground and a second laser distance measuring device for irradiating in aslant inside the measuring area, based on those distance measuring data, a three dimensional shape of material is measured. In accordance with movement of the object, the object shape is calculated using the data obtained from the second laser distance measuring device, a position of the object and the velocity are calculated using the data obtained from the first laser distance measuring device. Moreover, the surface shape of the object is calculated using the data with respect to the shape of the object over time. COPYRIGHT: (C)2008,JPO&INPIT
