Abstract: A method, system and apparatus of determining search parameters for welding seam point calibration. The method includes determining, for a seam vertex point on a welding seam, three reference faces which are perpendicular to each other, based on geometry of an object to be weld in a virtual model; and determining a start point and a search point of a search motion for welding seam point calibration based on the three reference faces and predetermined criteria respectively for the start point and the search point. Three reference faces can be extracted automatically, and search parameters needed for the search instructions can be determined based thereon which enables automatic generation of search instructions and thus the time, manpower and cost for the welding seam point calibration can be reduced greatly.
