Method and apparatus for control measurement of a motor vehicle frame and or aggregates connected thereto
First Claim
1. A method for carrying out control measurements of a measurement object, the measurement object having at least one reference measuring axis, the method comprising the steps of:
- mounting a guide means so as to extend transversely of the reference measuring axismounting a single light source for selective displacement on said guide means;
selecting a plurality of selected measuring control points on the measuring object;
placing plumb line rulers having measurement control values thereon at the selected measuring control points of the measuring object;
transmitting at least one light beam from the single light source in a direction substantially parallel to the reference measuring axis of the measurement object;
selectively displacing the single light source on said guide means to align said at least one light beam with the respective plumb line rulers;
determining a first coordinate of the measuring object by measuring the displacement of the single light source means along said guide means;
determining a second coordinate of the measurement object by measuring the distance between the light source and the respective plumb line means; and
determining a third coordinate of the measuring object by measuring the distance between a control measuring value on the plumb line ruler and the point at which the light beam strikes the plumb line ruler.

Abstract
A method and apparatus for undertaking control measurements of a measurement object such as a motor vehicle frame or unit installed thereon, in which a directional beam or beams are used which extend only parallel to one coordinate axis and in which only one light source is used which emits directional beams toward one or two sides; only one parallel guidance coordinated thereto is provided which is securely connected at least indirectly with the vehicle, extending preferably perpendicularly to the vehicle longitudinal axis underneath the vehicle floor; the position of the control points perpendicular to the direction of the parallel guidance will be determined by direct mechanical measurements of the distance between the corresponding plumbing rulers, on the one hand, and the parallel guidance or a fixed point at the beam source, on the other.

7. An installation for control measurement of a measuring object, the installation comprising:
-
a single light means for emitting a light beam extending substantially parallel to only one coordinate axis of the measuring object, guide means for selectively displaceably guiding the light source means on the measuring object, means for mounting said guide means on the measuring object so as to extend perpendicularly to the emitted light beam, a plurality of control points provided on the measuring object, means mounted at at least one of the respective control points and at the light source means for determining a first coordinate of the measuring object, means for determining a second coordinate of the measuring object between a fixed point and said means mounted at the respective control points, and means for determining a third coordinate of the measuring object indicative of a displacement of said light source means on said guide means. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64)
