Abstract
A method for cargo load detection in a container by a computing device, the method including projecting at least one light dot within an array of light dots towards a surface of the container; capturing an image of the at least one light dot on the surface of the container; and using the captured image to determine cargo loading within the container.
Claims15
A method for cargo load detection in a container by a computing device, the method comprising:
- capturing a first image of an interior of the container when the container is empty;
- detecting a first set of edges within the first image;
- capturing a second image of the interior of the container;
- detecting a second set of edges within the second image;
- and
- determining cargo loading within the container by comparing the first set of edges with the second set of edges, the comparing comprising determining that a missing portion of at least one edge within the first set is missing from the second set, wherein the determining is based on a ratio of a length of the missing portion to a length of the at least one edge.
A computing device for cargo load detection in a container, the computing device comprising:
- a processor;
- and
- a communications subsystem;
- wherein the computing device is configured to:
- capture a first image of an interior of the container when the container is empty;
- detect a first set of edges within the first image;
- capture a second image of the interior of the container;
- detect a second set of edges within the second image;
- and
- determine cargo loading within the container by comparing the first set of edges with the second set of edges, the comparing comprising determining that a missing portion of at least one edge within the first set is missing from the second set, wherein the determining is based on a ratio of a length of the missing portion to a length of the at least one edge.
A non-transitory computer-readable medium having stored thereon executable code for execution by a processor of a computing device, the executable code comprising instructions for
- capturing a first image of an interior of the container when the container is empty;
- detecting a first set of edges within the first image;
- capturing a second image of the interior of the container;
- detecting a second set of edges within the second image;
- and
- determining cargo loading within the container by comparing the first set of edges with the second set of edges, the comparing comprising determining that a missing portion of at least one edge within the first set is missing from the second set, wherein the determining is based on a ratio of a length of the missing portion to a length of the at least one edge.
