| titleOfInvention | Welding spot width detection method |
| abstract | The application provides a method for detecting the width of a welding spot, which comprises the steps of obtaining an image to be detected; determining a welding spot detection area in the image to be detected, and correcting welding spots in the welding spot detection area to obtain a target welding spot; according to a preset path, taking training characteristic points as starting points, passing through intermediate points, and determining a polygon detection area of the target welding point, wherein the polygon detection area is in the welding point detection area; processing and expanding the polygon detection area through a blob tool, and determining a minimum rectangular fitting area of the target welding point; positioning a welding spot left side line search box and a welding spot right side line search box in the minimum rectangular fitting area, and determining the left side line and the right side line of the welding spot; and determining the width of the welding spot according to the first intersection point and the second intersection point. This application is constantly dwindling the testing range in-process, filters miscellaneous point, reduces the interference, improves the positioning matching degree of accuracy and solder joint width detection precision among the testing process. |
