Title:
METHOD AND DEVICE FOR MEASURING VOLUME
Document Type and Number:
Japanese Patent JPH01141307
Kind Code:
A
Abstract:
PURPOSE:To obtain the method by which the minimum volume of a virtual hexahedron can be measured quickly and with high accuracy by allowing an object to be measured to abut on a corner part of three orthogonal reference surfaces and measuring a position of the corner part of the virtual hexahedron to which the object to be measured is inscribed. CONSTITUTION:Three reference surfaces 1, 2a and 2b being orthogonal to each other are formed, and an object to be measured is placed on the base 1 among them, and also, a side part of the object to be measured is allowed to abut on the other side walls 2a, 2b. Subsequently, the minimum virtual hexahedron to which the object to be measured is inscribed is supposed, and a corner part 6 which is not abutting on each reference surface 1, 2a and 2b of its virtual hexahedron is determined. Next, this corner part 6, an intersection A of the reference surfaces 2a, 2b and a distance 4 between this intersection A and points B, C being in the same plane are measured, and a spatial position of the corner part 6 is specified. In the end, from a position of this corner part 6, volume of the virtual hexahedron is calculated.
