Abstract

Methods and systems for tracking a package within an area obtain package identification information from a scannable medium associated with the package and image information of the area acquired by an optical sensing device. Image processing detects the presence and location of an object in the area that matches the package based on a comparison of the package identification information obtained from the scannable medium with the image information of the area acquired by the optical sensing device. The package is registered as being present in the area at the location of the detected object in response to detecting a match between the object and the package.

First claim

What is claimed is:

1. A method for tracking a package within an area, comprising:
obtaining by a data acquirer, package identification information from a scannable medium associated with the package;
acquiring by one or more sensors, image information of the area;
detecting motion at a location in the area based on the image information acquired of the area;
detecting an object at the location in the area in response to detecting the motion based on the image information acquired of the area, including: determining at least one of: a movement, a presence, and a position of the object; or a velocity of the movement of the object: at the location in response to integrating and comparing images of the image information acquired at different times;
confirming by a computing system, whether the object appearing in the image information is the package associated with the obtained package identification information by:
acquiring, from the image information, a distinguishing characteristic of the object at the location in the area; and
comparing the distinguishing characteristic of the object detected in the area with the package identification information obtained from the scannable medium, the method further comprising:

identifying the package, in response to the comparison satisfying a criterion, as the object at the location in the area by associating the image information about the object with the package identification information;
registering the package as being present in the area at the location of the detected object in response to the comparison satisfying the criterion; and
continuously tracking, within the area where the object was detected and the package was registered, the package to determine whether the registered package is at a different position from the location of the detected object.

2. The method of claim 1 , further comprising:
displaying a representation of the area; and
marking the location of the registered package on the displayed representation with at least a portion of the package identification information obtained from the scannable medium associated with the package.

3. The method of claim 1 , further comprising guiding placement of the package to the location in response to obtaining the package identification information from the scannable medium associated with the package.

4. The method of claim 3 , wherein the step of guiding placement of the package into the area includes illuminating the location where the package is to be placed.

5. The method of claim 1 , wherein the package identification information includes at least one of: physical dimensions of the package, a destination address for the package, a name of the package, routing information for the package, and markings on the package.

6. The method of claim 1 , wherein the image information of the area is three-dimensional (3D) image information.

7. The method of claim 1 , further comprising guiding a search for the package in the area by illuminating at least a portion of the package.

8. The method of claim 1 , further comprising: generating the image information acquired of the area from a combination of at least one camera and at least one depth sensor.

9. The method of claim 1 , wherein acquiring the distinguishing characteristic of the object detected at the location in the area comprises executing an edge detection technique to determine dimensions of the package.

10. A method for tracking a package within an area, comprising:
obtaining, by a data acquirer, package identification information from a scannable medium associated with the package;
automatically acquiring, by one or more sensors, image information of the area;
detecting motion at a location in the area based on the image information acquired of the area, including determining at least one of: a movement, a presence, and a position of the package; or a velocity of the movement of the package; at the location in response to automatic image processing including integrating and comparing images of the image information acquired at different times;
detecting, by a computer processor in electronic communication with both the data acquirer and the one or more sensors, an object at the location in the area in response to detecting motion based on the image information acquired of the area;
confirming by a computer processor, whether the object appearing in the image information is the package associated with the obtained package identification information by:
comparing dimensions of the package determined from the image information processed by the automatic image processing with the package identification information obtained from the scannable medium, the method further comprising:

identifying the package, in response to the comparison satisfying a criterion, as the object at the location in the area;
registering the object as the package as being present in the area at the location of the detected object in response to the comparison satisfying the criterion; and
continuously tracking, within the area where the object was detected and the package was registered, the package to determine whether the registered package is at a different position from the location of the detected object.

11. The method of claim 10 , further comprising:
displaying a representation of the area; and
marking the location of the registered package on the displayed representation with at least a portion of the package identification information obtained from the scannable medium associated with the package.

12. The method of claim 10 , further comprising guiding placement of the package to the location in response to obtaining the package identification information from the scannable medium associated with the package.

13. The method of claim 12 , wherein the step of guiding placement of the package into the area includes illuminating the location where the package is to be loaded.

14. The method of claim 10 , wherein the package identification information includes at least one of: physical dimensions of the package, a destination address for the package, a name of the package, routing information for the package, and markings on the package.

15. The method of claim 10 , wherein the image information of the area is three-dimensional (3D) image information.

16. The method of claim 10 , further comprising guiding a search for the package in the area by illuminating at least a portion of the package.

17. The method of claim 10 wherein the data acquirer includes a scanner.

18. The method of claim 10 wherein the one or more sensors include a camera.

19. A system for package tracking, comprising:
one or more cameras configured to capture images of an area where packages are placed; and
an image processor configured to receive package identification information associated with a given package that is to be placed in the area, the image processor being further configured to:
detect, in the images captured by the one or more cameras, change corresponding to an object appearing in the images at a location in the area where packages are placed, wherein the object appearing in the images is unconfirmed as the given package associated with the received package identification information when the change is detected;
confirm whether the object appearing in the images is the given package associated with the received package identification information by:
acquiring, from the images captured by the one or more cameras, image data about the object that appeared at the location in the area where
