On Line Videooptical System for Weld Groove Analysis

The article shows the video-optical system for to recognition of location and size of weld groove. Was used special system equipped with two USB cameras (VGA resolution) and red laser laser. First of camera was used to recognition of groove location and second one with laser as mobile scanner was used to size of groove analyse. For proposed conception was prepared in Visual Basic 6.0 special software WELD_REC, which calculate the angle of groove location and the groove parameters: width, depth and angle of opening. Presented system is used for experiments using PC controlled IRb –60 industrial robot. The differences of location of groove: between well-known and video-optical measured have the highest of 3% .
