Abstract
A method for applying a sealing agent to a surface of an internal cavity of a pneumatic tire includes inserting an optoelectronic device into the internal cavity and rotating the tire at least 360 degrees about a first axis to acquire captured images and perform a three-dimensional surface scan of various portions of the surface that are uniformly distributed 360 degrees about the first axis, and thereby identify x, y, and z reference coordinates of various points into which each portion is divided as a function of the respective images. An interior surface profile is determined from the images and the identified reference coordinates, an applicator device including a nozzle is inserted into the internal cavity, and the applicator device is driven as a function of the identified three-dimensional reference coordinates of the entire internal cavity to maintain a constant distance between the applicator device and the surface.
