ABSTRACT:
A line projection part provided on a distal-end part of an endoscope for projecting a light of a line toward the side of an object. A plurality of points are assigned on a line which is projected so as to pass through a recess or the like which resides in an object surface, to calculate an approximate line which expresses the line three-dimensionally. Further, a measurement point is assigned onto the line which passes through the recess, to find a three-dimensional coordinate thereof. A distance from the three-dimensional coordinate to the approximate line is found to calculate a depth of the recess or the like.
