Method for the computer-aided recognition of a transport container being empty and device for the computer-aided recognition of a transport container being empty

A method for computer-aided recognition of a transport container being empty, the method comprising:

• arranging the transport carrier in an image capture region;
• capturing a multiplicity of image data of the image capture region wherein said multiplicity of image data represents one of a temporal sequence and a spatial sequence of the transport container including a transport region of the transport container, wherein the image capture region defines an image background of the transport container;
• determining respective contour patterns in each of the multiplicity of image data, wherein each respective contour pattern represents the transport container;
• determining respective contour densities in each of the multiplicity of image data;
• recognizing a type of the transport container based on the contour density in at least one image data of the multiplicity of image data;
• discarding the multiplicity of image data other than the at least one image data recognized during said recognizing;
• determining if the contour pattern in the at least one image data recognized during said recognizing includes a disturbance in the transport region of the transport container;
• determining a deviation variable, which represents a deviation of the contour pattern in the at least one image data recognized during said recognizing caused by the disturbance from at least one reference pattern, wherein the at least one reference pattern represents an empty transport container while the transport carrier is in the image capture region and comprises a contour pattern representing the image background;
• and
• outputting a signal if the deviation variable satisfies a predefined criterion.
