TECHNIQUES FOR SEAM LOCALIZATION AND GAP MEASUREMENT

Abstract: this disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, which provide for welding techniques for manufacturing robots, such as seam localization, gap measurement, or both. for example, the welding techniques may include, during illumination of one or more objects by a light source, controlling a camera to capture images of the one or more objects along at least a portion of a length of a seam formed by the one or more objects. the techniques further include differentiating, in the images, the seam from the one or more objects. in a first aspect, the techniques also include triangulating the differentiated seam to identify a position of the seam relative to a reference point. in a second aspect, the techniques also include determining, based on the differentiated seam, gap information along a portion of the seam. other aspects and features are also claimed and described.
