In the industry, the automation of brazing system is
very important using the vision senor and the edge detection of the
bronze pipe. And also, the accurate coordination is needed for the
finding of the precise location. In this paper, we propose an
algorithm for the measurement of 3D information of the
brazing material and the detection algorithm of soldering area
using the camera and IR sensor. We use Canny edge detector in
noisy environments. The experimental study shows that camera and
IR sensor is useful for the measurement of distance in the brazing
work .
