Abstract
A method for quality assessment of a sealing section of a package, wherein the package includes at least a robustness layer and a plastic layer. The sealing section is formed by holding a first section and a second section of the package against each other while providing heat such that the plastic layer of the first and second section melt and thereby provide for that the first and second section adhere to each other. The method includes capturing image data depicting the sealing section using a camera, identifying a reference line in the image data, identifying a sealing section boundary line in the image data, determining a sealing section assessment feature set based on the reference line and the sealing section boundary line, and comparing the sealing section assessment feature set with a reference feature set.
