Title:
MEASURING DEVICE FOR THREE DIMENSIONAL SHAPE AND ITS MEASURING METHOD
Document Type and Number:
Japanese Patent JP3434425
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To accurately measure a measured object which is different in an individual shape and the characteristics of reflection factor of a surface.
SOLUTION: In a laser three dimensional shape measuring device, a direction where a distance measuring means 1 and a measured object M mutually approach and separate is set up as a Z-axis direction, and a measuring means 18 for detecting measured data from distance data in the case of measuring the optional measuring point of the measured object M by a distance measuring means 1 and the moving position data in a Z-axis direction of a moving position detecting means 7 is provided, and the highly accurate measurement of the shape of the measured object which is different in an individual shape and the characteristics of reflection factor of a surface is made possible by carrying out control for calibrating the distance data in the case of a regular measurement made through the distance measuring means 1 on the measuring data.
