Automobile production line

The most hard jobs in the subsequent stages of automobile system is the dimensional assessment of this gaps amongst the automobile human anatomy plus the various panels fitted onto it (doors, motor-hood, etc.). The work of a computerized gap-measuring system would decrease the costs significantly and would provide high mobility. However, this task is still performed by humans and only several — however experimental — automated methods have already been reported. Inside report, we introduce a method for automated gap assessment that hires computer system eyesight. It is capable of measuring the horizontal additionally the range measurement regarding the space (circumference and flush, correspondingly). The measurement set up is made of two calibrated stereo cameras as well as 2 infrared Light-emitting Diode lamps, used for highlighting the edges for the space through specular reflection. The gap is calculated as the 3D distance between your highlighted sides. This process features considerable advantages against the laser-based, gap-measuring systems, due primarily to its color independency. Our method is analytically described in 2D and extensively evaluated utilizing artificial and real spaces. The outcomes obtained verify its robustness and its usefulness in a commercial environment.
