The present invention provides a
welding groove
feature extraction method,
system and
welding robot, the method comprising: obtaining
surface depth information data of the weld groove of a steel component and performing preprocessing to obtain the
welding groove area, determining the position of the inflection point above the groove in any cross section in the welding groove area, judging and screening out standard welding groove cross sections, determining the position of the inflection point at the bottom of the groove in the cross section, obtaining the inflection point position information in each cross section, screening the inflection point position information in each cross section to obtain target inflection point position information in each cross section, judging the type of steel component, performing secondary
processing on the target inflection point position information according to the steel
component type, determining the start and end positions of the groove, and obtaining target groove feature information. The present invention adopts a data
screening method to greatly reduce the
data processing volume and improve the
algorithm operation efficiency; at the same time, it adopts a multi-
algorithm fusion to achieve accurate extraction of welding groove feature inflection points, thereby improving the accuracy and efficiency of welding groove
feature extraction.
