Abstract
The invention relates to a device for determining the volume of an object moved by an industrial truck and to a corresponding method. The device comprises a first depth image sensor (3) and a second depth image sensor (4), which are arranged in such a way that the object (1) can be sensed from two different directions as the object passes through the passage region (5), wherein the device (10) is designed to produce a sequence of individual images in a first resolution by means of each of the depth image sensors (3, 4), whereby the industrial truck (2) and the object (1) are sensed from different viewing angles as the industrial truck and the object pass through the passage region (5). The device also comprises a volume-determining apparatus (11), which is designed to subject the sequences of the individual images in the first resolution of the first depth image sensor (3) and of the second depth image sensor (4) to a super resolution processing in order to create a 3-D model (17) comprising the industrial truck (2) and the object (1) in a second resolution that is higher than the first resolution and to determine the volume of the object (1) on the basis of the produced 3-D model (17).

18. A device for determining a volume of an object moved by an industrial truck, comprising:
-
a first depth image sensor and a second depth image sensor, which are arranged such that the object can be sensed from two different directions as the object passes through the passage region, wherein the device is designed to produce sequences of single images in a first resolution with each of the depth image sensors, whereby the industrial truck and the object are sensed from different viewing angles as they pass through the passage region; and a volume-determining apparatus, which is designed to subject the sequences of the single images in the first resolution of the first depth image sensor and of the second depth image sensor to super resolution processing so as to create a 3-D model comprising the industrial truck and the object in a second resolution that is higher than the first resolution, and to determine the volume of the object on the basis of the 3-D model produced. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A method for determining the volume of an object moved by an industrial truck, comprising the steps:
-
(a) arrangement of a first depth image sensor and a second depth image sensor in a passage region of the object being moved, such that the object can be sensed from two different directions as it passes through the passage region; (b) production of sequences of single images in a first resolution with each of the depth image sensors, which show the industrial truck and the object from different viewing angles as the latter pass through the passage region; (c) production of a 3-D model comprising the industrial truck and the object with a second resolution, which is higher than the first resolution, by executing super resolution processing on a basis of the sequences of single images in a first resolution of the first depth image sensor and the second depth image sensor; and (d) determination of the volume of the object on the basis of the 3-D model produced.
