Sensing cargo using an imaging device
First Claim
Patent Images
1. A method comprising:
- receiving a signal requesting an indication of whether cargo is present in a cargo space from a remote source;
capturing, using a light sensor, an image of at least a portion of the cargo space;
classifying, using a learning classifier located within the cargo space, the captured image to determine a type of content within the cargo space, wherein the type of content comprises making a determination of cargo capacity used and the manner of use; and
outputting, to a location that is remote from the cargo space and based on the classifying, an indication of a presence and characteristics of cargo, an absence of cargo or a presence and characteristics of non-cargo items.

Abstract
A camera is used to sense cargo in a cargo space. An image of at least a portion of a cargo space is captured using the camera, and a digital signal processor classifies the image as representing an empty cargo space or a non-empty cargo space. Additionally, a type of cargo represented by the captured image may also be classified by the digital signal processor and an indication of the type of cargo output.

12. A system comprising:
-
a module to receive a signal, from a remote source, requesting an indication of whether cargo is present in a cargo space; a camera to capture an image of at least a portion of the cargo space; and a digital signal processor, coupled to receive the image from the camera, to classify the image as representing an empty cargo space or a non-empty cargo space, including; a classification module located within the cargo space to extract characteristics from the image and determine, based on learned characteristics from training images, a type of content within the cargo space to provide an indication of an absence of cargo, a presence and characteristics of cargo or a presence and characteristics of non-cargo items, wherein classifying the type of content comprises making a determination of cargo capacity used and manner of use. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. One or more computer readable media having computer readable instructions stored thereon that, when executed by a processor, causes the processor to:
-
receive a signal, from a remote source, requesting an indication of whether cargo is present in a cargo space; access at least a portion of an image of at least a portion of the cargo space, wherein the image was generated by sensing light at a particular frequency range; classify, from within the cargo space, the captured image to determine a type of content within the cargo space, wherein classifying the type of content comprises making a determination of cargo capacity used and the manner of use; and output to a location remote from the cargo space, based on the classification, an indication of a presence and characteristics of cargo, an absence of cargo or a presence and characteristics of non-cargo items. - View Dependent Claims (20, 21)

22. A method comprising:
-
capturing, using a light sensor, an image of at least a portion of a cargo space; classifying from within the cargo space, based on one or more training images, a type of cargo represented by the captured image to determine a type of content within the cargo space, wherein the type of cargo comprises making a determination of cargo capacity used and the manner of use; and outputting, to a location remote from the cargo space and based on the classifying, an indication of a presence and characteristics of cargo, an absence of cargo or a presence and characteristics of non-cargo items. - View Dependent Claims (23, 24, 25, 26, 27)

28. A system comprising:
-
a module to receive a signal, from a remote source, requesting an indication of whether cargo is present in a cargo space; a camera to capture an infrared (IR) or ultraviolet (UV) image of at least a portion of the cargo space; and a digital signal processor located within the cargo space implementing a learning classifier to classify the image to determine a presence and characteristics of cargo in the cargo space, an absence of cargo in the cargo space or a presence and characteristics of non-cargo items in the cargo space by classifying a type of content within the cargo space, wherein classifying the type of content comprises making a determination of cargo capacity used and the manner of use, and wherein the digital signal processor is coupled to receive the image from the camera. - View Dependent Claims (29, 30)
