摘要
Abstract
Submerged arc welding is one of the widespread welding technology.It has high efficiency,good weld quality.no arc radiation, etc.It is more and more important/To improve the submerged arc welding process automatic and intelligent, increasing demands for precision tracking technology.In order to improve the accuracy of submerged arc welding, a sub-pixel location based on B Spline transform was put forward for welding line and dibided edge.The algorithm is conducting a Marr-Hildreth edge detection and a sub-pixel location.Field tests,achieved standard error less than 255.The traditional edge detection was low in precision,but the problem is constraining by using the transform.关键词
