Abstract: A
new high accuracy 6D (Dimension) wide range measuring technology
and the method of coordinate transformations have been
developed in a project for automobile body-in-white measurement
in Michigan, U S A. The requirements and the special features
about the measured objective are mainly stated. The main
instruments used in the project are introduced. The 6D measuring
system, the method for coordinate transformations and the design
of 3D optical target with hollow tetrahedron are described in
detail. The 6D system and the technology can be certainly used
in many other kinds of geometric measuring projects.
Key words: Automobile
