AdventCR: A New Fully Automatic Optical Measuring System From ActiCM Uses Contactless Photogrammetry Technology
Chicago, February 22, 2005
ActiCM is pleased to introduce a new non-contact fully automatic optical measuring system for ultra-fast off-line control and inspection of car bodies called the AdventCR. The product is a 3D measuring system designed for use on production lines. It can be used for both geometric and surface point measurements 10 times faster than current CMMs. Its accuracy is 50 to 300 microns depending on the material and the measurement volume.
AdventCR 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 several light sources. Each IDV 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.
Delighted with this product's performance, car manufacturer Renault plans to purchase an AdventCR in 2005. The new system is even more efficient than the prototype they just had validated, which only had one IVD (Intelligent Vision Device). Renault's future acquisition of the AdventCR will incorporate 4 IVDs, reducing control times even more.
"Today, measuring the complete car body takes eight to ten hours, against two hours with the AdventCR prototype," said Baptiste Faivre d'Arcier, leader of the PACA (Photogrammetry Applied to car bodies) project at Renault, which validated the AdventCR prototype. "These two hours can be reduced to 30 minutes if we use 4 IVDs, and the cost of this system would still be equivalent to that of a current CMM. Calculations and measurements can be deferred, so that the measured part is available immediately."
The Advent range is available in several versions: AdventCR for automobile manufacturing production lines; AdventSU for automotive sub-contractors; AdventSP for the aeronautics sector; and AdventME for mechanical machining. These different versions will be marketed progressively from 2005 to 2007.
ActiCM will be at the following trade fairs: Industrie Lyon (France) from March 8 - 11, 2005; Control at Sinsheim (Germany) from April 26 - 29, 2005; Intermach in Bangkok (Thailand) from May 11 - 15, 2005; and CMOI in Marseille (France) from November 23 - 24, 2005.
