Sensing cargo using an imaging device
First Claim
Patent Images
1. A method comprising:
- capturing, using a light sensor, an image of at least a portion of a cargo space;
classifying, using a learning classifier, the captured image as representing either the presence of cargo or the absence of cargo; and
outputting, based on the classifying, an indication as to whether cargo is present in the cargo space.

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.

20. One or more computer readable media having stored thereon a plurality of instructions that, when executed by a processor, causes the processor to:
-
access at least a portion of an image of at least a portion of a cargo space, wherein the image was generated by sensing light at a particular frequency range;
classify the captured image as representing an empty cargo space or a non-empty cargo space; and
output, based on the classification, an indication as to whether the cargo space is empty or non-empty. - View Dependent Claims (21, 22)

23. A method comprising:
-
capturing, using a light sensor, an image of at least a portion of a cargo space;
classifying, based on one or more training images, a type of cargo represented by the captured image; and
outputting, based on the classifying, an indication of the type of cargo present in the cargo space. - View Dependent Claims (24, 25, 26, 27, 28, 29)

30. A system comprising:
-
a camera to capture an infrared (IR) or ultraviolet (UV) image of at least a portion of a cargo space; and
a digital signal processor implementing a learning classifier to classify the image as representing either the presence of cargo in the cargo space or the absence of cargo in the cargo space, wherein the digital signal processor is coupled to receive the image from the camera. - View Dependent Claims (31, 32, 33)
