Abstract
A method for recognizing a viewed object in a warehouse comprises detecting image data comprising a plurality of pixels with a 3D camera attached to an industrial truck, wherein information regarding a distance from the viewed object to the 3D camera is assigned to each pixel. Creating a two-dimensional data set by projecting the plurality of pixels on a projection plane and comparing the two-dimensional data set with a predefined pattern representing a reference object. Determining a provisional recognition of a viewed object at a position in the projection plane based on a correspondence found in the comparison. Creating a second data set that comprises a depth profile along a line at the position of the projection plane and comparing the second data set with a predefined depth profile pattern assigned to the reference object. The final recognition of the viewed object occurring when a correspondence is found in the comparison of the second data set with a predefined depth profile pattern assigned to the reference object.
