Method and system for glass processing

摘要

A mixture of glass pieces can be evaluated by taking an image of an object from the mixture. The object has the possibility of being either a single piece of glass from the mixture or at least two pieces of glass from the mixture. By knowing how many pieces of glass are in each object, the accuracy of the evaluation can be improved. Angles of an outline of the object are determined from the image, and then the angles are evaluated to determine whether the object is at least two pieces. When it is determined that the objection is at least two pieces, it is possible to assign a characteristic, such as color type or material type, for each piece as opposed to assigning the same characteristic to the entire object.

主权项

1. A method for evaluating a mixture including a plurality glass pieces, the method comprising:
taking an image of an object from the mixture, the object possibly being either a single piece from the mixture or at least two pieces from the mixture; determining, from the image, angles of an outline of the object; evaluating the angles to determine whether the object is at least two pieces; evaluating a characteristic of the object; detecting, from the image, a light transmittance boundary line within the outline of the object, the light transmittance boundary line having an endpoint on the outline; evaluating a position of an endpoint on the outline to determine whether the light transmittance boundary line is present on a single piece of the mixture; and identifying the single piece of the mixture as a piece of glass with a label when the light transmittance boundary line is determined to be present on a single piece of the mixture.
