The company ActiCM has been selected by RENAULT, the French car manufacturer, to deploy Advent™, an automated non contact coordinate measuring system for high speed car body inspection.

Advent™ is a vision based system, which relies on a combination of advanced photogrammetry and powerful digital image processing. This unique combination provides a high level of accuracy in the results obtained, whilst increasing the reliability and rapidity of controls performed on parts, organs or complex assemblies, both on and off the production line.

Advent™ is a complete solution composed both of software and hardware. The software takes in charge the powerful calculation & analysis of the image processing, the photogrammetry process and the results analysis & statistics report. The hardware gets the data, and includes up to 8 IVDs™ (Intelligent Vision Device), a very compact optical sensor that incorporates two high resolution digital high definition CCD cameras, along with an Infra Red light source and a White Light projector. This allows both geometric control and surface point measurements. Each IDV can be mounted on a robot’s arm or in a measurement tunnel.

« today, it takes 8 to 10 hours to control a full car body of a prototype, when Advent takes only two hours », says Baptiste Faivre d'Arcier, the manager of PACA (Photogrammétrie Appliquée à la Carrosserie Automobile) at Renault, who tested the different systems in competition. These two hours can be cut by two when using two IDVs.

Advent™ can accept up to 8 IVDs, is 10 times faster than any current CMM and provides measurement accuracy up to 0.03 pixels. It aims at the aeronautics, automotive and the transport equipment production sector.



About ActiCM

ActiCM will be present at Industrie “Interqualité” 2004 trade show taking place in Paris from 22 to 26 March 2004 and at Control 2004 trade show taking place in Germany from 11 to 14 May 2004. ActiCM is based in South-Eastern France (near Grenoble). The company was set up in 2000 and their aim was to make available to manufacturers novel and high-performance optical technology platforms. ActiCM’s technology is the outcome of 10 years of R&D and is protected by various patents internationally. ActiCM’s technology yields considerable productivity gains in the field of industrial measurements and controls.
