Problems solved by technology

In the measuring methods disclosed in US Pat. No. 4,498,776 and US Pat. No. 5,129,010, it is also problematic that the flushness is only measured point-by-point along a sampling line that is ideally tangential to the gap to be measured.

Embodiment Construction

[0013] figure 1 The measuring device for determining the play and flushness of body parts 101 , 102 of a motor vehicle shown in includes a three-dimensional alignment of the body parts to be aligned with each other over a plurality of predeterminable measuring areas 141 101, 102 A plurality of sampling devices 104 for sampling. In this case, the sampling device 104 is aimed at a plurality of body joints 103 and is realized, for example, by means of a laser scanner. Measurement range 141 is parameterized vehicle-specifically. Sampling device 104 can thus be aligned with body joint 103 by means of predetermined vehicle-specific parameterization 156 . Vehicle-specific parameterization 156 is connected in data memory 154 of computer unit 105 connected to sampling device 104 . Simultaneous measurement of several body joints 103 is achieved by activating sampling device 104 by means of computer unit 105 .

[0014] In addition to a data memory 154 , computer unit 105 includes a p...

Abstract

The method involves scanning the body sections (101,102) to be assigned to each other in a dimensional manner in multiple predetermined measuring ranges (141) by a scanning device. The scanning devices are aligned on a body joint (103). The three dimensional surface elements assigned to the aligned body sections are determined within a measuring range from the scanned values determined by the scanning device. Independent claims are also included for the following: (1) a control program for executing the method; and (2) a measuring device for determination of clearance or concision of body sections of a motor vehicle.

Description

technical field [0001] Gaps and flushnesses are created between the body parts when joining the body parts of the motor vehicle. Within the scope of the quality inspection, play and flushness are preferably measured automatically for the control of a robot or in a feedback loop. In such a measurement, the determined measured values ​​are also forwarded, for example, to a superordinated production automation system. Background technique [0002] To measure the play and flushness of body parts, two-dimensional measuring methods have hitherto been used, which are based on laser triangulation systems or on special lighting systems, by means of which the edges are particularly well visible for camera recording. Laser triangulation systems only provide measured values ​​along sampled lines or sampled curves, for example as projections of edges of curved surfaces onto viewing or measuring planes. The relevant analysis algorithms are therefore only able to analyze curves that run ...
