Technology of Non-Contact Measurement of Automobile Gap for Semi-Automatic Use

Abstract

The paper represents infrared laser and digital camera based equipment for measurement of gap and flushness on the automobile. The system is based on smartphone that is used as camera and database, while the red laser is targeted as measurement tool. The method used to measure the gap and flushness is based on laser triangulation. The camera on the smartphone captures the laser line projected on the body of the automobile and serves as database of captured photos. The measurement algorithm is done on remote computer based algorithm that serves as computation station for gap and flushness measurement. Experiments are done on real car body in laboratory conditions. The process is done as effective replacement of operator’s gap and flushness measurement in the production process. The results enable to eliminate the operators’ error and help to implement semi-automatic measurement system in theproduction plan.
