Method and system for cargo load detection
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.
1. 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.
2. The method of claim 1 , wherein the determining is based on a length of the missing portion.
3. The method of claim 1 , wherein the determining is based on a location of the missing portion.
4. The method of claim 1 , wherein the determining identifies a size and a location of a load.
5. The method of claim 1 , further comprising transmitting the second image to a server;
wherein the server performs the determining.
6. The method of claim 1 , wherein the first image and the second image are captured by a camera located at a rear of the container projecting forward.
7. The method of claim 1 , wherein the first image and the second image are captured by a camera located at a front of the container projecting backwards.
8. 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.
9. The computing device of claim 8 , wherein the determining is based on a length of the missing portion.
10. The computing device of claim 8 , wherein the determining is based on a location of the missing portion.
11. The computing device of claim 8 , wherein the determining identifies a size and a location of a load.
12. The computing device of claim 8 , wherein the computing device is further configured to transmit the second image to a server;
wherein the server performs the determining.
13. The computing device of claim 8 , wherein the first image and the second image are captured by a camera located at a rear of the container projecting forward.
14. The computing device of claim 8 , wherein the first image and the second image are captured by a camera located at a front of the container projecting backwards.
15. 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.
