Abstract
A system for generating a pixel map of a yard or facility in substantially real-time. The pixel map may be generated on-the-fly with virtual slots based on various vehicles and containers entering and exiting the yard or facility. In some cases, the pixel map may be utilized to track assets within the facility even if the physical identifier of the asset is unknown or the asset transitions between field of view of various image devices associated with the system.
Claims18
A system comprising:
- a first fixed image device to capture first image data associated with a physical environment;
- a second mobile image device to capture second image data associated with assets parked within the physical environment;
- and
- an asset tracking system configured to:
- generate, based at least in part on the first image data, a pixel map of the physical environment, the pixel map including at least a first slot and a second slot, the first slot is defined based on a first set of pixels of the pixel map and the second slot is defined based on a second set of pixels of the pixel map, the first set of pixels different than the second set of pixels;
- detect, based at least in part on the first image data, a first asset within the first slot;
- assign a virtual identifier to the first asset;
- associate the virtual identifier with the first slot, wherein the first slot is a first virtual slot;
- determine, based at least in part on portions of the second image data captured while the first asset is positioned within the first slot, a physical identifier associated with the first asset;
- associate the virtual identifier with the physical identifier;
- determining, based at least in part on third image data, that the first asset has moved;
- defining, based at least in part on pixels within the third image data representing the first asset, a second virtual slot within the pixel map of the physical environment;
- associating the virtual identifier with the second virtual slot;
- and
- removing the first virtual slot from the pixel map.

A method comprising:
- detecting, based at least in part on first image data, an asset within a physical environment;
- assigning a virtual identifier to the asset;
- determining, based at least in part on second image data, that the asset has been parked within the physical environment, the second image data received subsequently to the first image data;
- defining, in response to determining that the asset has been parked based at least in part on pixels within the second image data representing the asset, a virtual slot within a pixel map of the physical environment;
- associating the virtual identifier with the virtual slot, wherein the virtual slot is a first virtual slot;
- and
- causing the pixel map to be displayed at a display associated with the physical environment, the pixel map including data indicating the virtual slot and an occupancy of the virtual slot;
- determining, based at least in part on third image data, that the asset has moved;
- defining, based at least in part on pixels within the third image data representing the asset, a second virtual slot within the pixel map of the physical environment;
- associating the virtual identifier with the second virtual slot;
- and
- removing the first virtual slot from the pixel map.

One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- detecting, based at least in part on first image data, an asset within a physical environment;
- assigning a virtual identifier to the asset;
- determining, based at least in part on second image data, that the asset has been parked within the physical environment, the second image data received subsequently to the first image data;
- determining, based at least in part on second image data, that the asset has been parked within the physical environment for greater than a predetermined period of time, the second image data received subsequently to the first image data;
- defining, responsive to determining that the asset has been parked within the physical environment for greater than the predetermined period of time and based at least in part on pixels within the second image data representing the asset, a virtual slot within a pixel map of the physical environment;
- associating the virtual identifier with the virtual slot, wherein the virtual slot is a first virtual slot;
- and
- causing the pixel map to be displayed at a display associated with the physical environment, the pixel map including data indicating the virtual slot and an occupancy of the virtual slot;
- determining, based at least in part on third image data, that the asset has moved;
- defining, based at least in part on pixels within the third image data representing the asset, a second virtual slot within the pixel map of the physical environment;
- associating the virtual identifier with the second virtual slot;
- and
- removing the first virtual slot from the pixel map.
