ActiCM's AdventCR measures up for Renault
ActiCM's AdventCR™ measures up for Renault
Keywords: Automotive industry, Measurement
AdventCRe is a non-contact fully automatic 3D optical measuring system, for ultra-fast off-line control and inspection of car bodies, designed for use on production lines. It can be used for both geometric and surface point measurements and is ten times faster than current systems. It is accurate to between 50 and 300 mm, depending on the material and the measurement volume. RENAULT will purchase a version that is even more efficient than the prototype the French car maker has approved, which had only one IVD (intelligent vision device), whereas the final version will have four IVDs, to reduce control times even further (Plate 1).

“Today, measuring the complete car body takes 8-10 hours, as opposed to 2 hours with the AdventCRe prototype,” said Baptiste Faivre d'Arcier, leader of the PACA project (Photogrammétrie Appliquée à la Carosserie Automobile – photogrammetry applied to car bodies) at RENAULT, which validated the AdventCR™ prototype. These 2 hours can be reduced to 30 min if four IVDs are used, and the cost of this system would still be equivalent to that of a current CMM (coordinate measuring machine). Calculations and measurements can be deferred, so that the measured part is available immediately.
AdventCR™ is a complete solution composed both of software and hardware. The software handles the powerful calculation and analysis of the image processing, the photogrammetry process and the results analysis and statistics report. The hardware manages the data, and includes up to eight IVDs – a very compact optical sensor that incorporates two digital high-definition CCD cameras, along with several light sources. Each IVD can be mounted in a measurement tunnel or on a robot's arm. The robot is only used for transporting the IVD and is not involved in the system's precision chain in any way.
The Advent™ range is available in several versions – AdventCR™ for automobile manufacturing production lines, AdventSU™ for automotive sub- contractors, AdventSP™ for the aerospace sector and AdventME™ for mechanical machining. These different versions will be marketed progressively from 2005 to 2007.
