Paper Abstract
Detecting 3-D information on welding pool surface shape is difficult due to the arc light interference, high temperature
radiation and pool surface specular reflection. The characteristics of mirror like reflection on pool of liquid surface are
studied. Besides the way to obtain clear information-rich image of the pool area is discussed under the strong arc light.
Because of the strong arc light above the pool will affect the imaging of the relatively weaker laser stripes seriously, we
need to choose a suitable shooting angle and shooting distance to achieve well image. According to all these factors, the
optimal combination of the sensing structure parameters in theory is deduced. Based on this work, a vision detecting of
arc welding pool surface topography system was putted up in our laboratory, also actual measurement was carried out to
obtain more clear images of deformation laser stripes in welding pool. This will provide the three-dimensional
reconstruction a strong support.
