Method and system for identifying waste containers based on pattern

摘要

There is provided a method for identifying and sorting randomly distributed waste containers (1) containing different types of refuse sorted at source, wherein the identification is based on an image analysis of a pattern (2) arranged on each container (1). The method for identifying and sorting comprises the following steps: capturing at least one image of each container (1), analyzing the image by determining following characteristics: a shade and/or color of the pattern; a type of the pattern arranged on the container; calculating a sorting value based on the determined characteristics; comparing the calculated sorting value to a predetermined limit value or predetermined range of sorting values in order to classify the type of refuse contained in the container for sorting thereof.

1. A method for identifying and sorting randomly distributed waste containers transported on a conveyor, said waste containers consisting of a thin-walled bag of flexible material containing different types of refuse sorted at source, wherein the identification is based on an image analysis by an optical camera of a pattern arranged on each container, the method for identifying and sorting comprising the following steps:
capturing, by at least an optical camera, at least one image of each container; analyzing the image, by a computer, by determining the following characteristics:
a shade and/or color of the pattern; anda type of the pattern arranged on the container by determining a shape factor; calculating a sorting value based on the determined characteristics; comparing the calculated sorting value to a predetermined limit value or predetermined range of sorting values in order to classify the type of refuse contained in the container for sorting thereof, and sorting by selectively striking or pushing a waste container away from the conveyor belt.
