SYSTEM AND A METHOD FOR TRACKING MOBILE OBJECTS USING CAMERAS AND TAG DEVICES

摘要

A method and system for tracking mobile objects in a site are disclosed. The system comprises a computer cloud communicating with one or more imaging devices and one or more tag devices. Each tag device is attached to a mobile object, and has one or more sensors for sensing the motion of the mobile object. The computer cloud visually tracks mobile objects in the site using image streams captured by the imaging devices, and uses measurements obtained from tag devices to resolve ambiguity occurred in mobile object tracking. The computer cloud uses an optimization method to reduce power consumption of tag devices.

主权项

1. A system for tracking at least one mobile object in a site, the system comprising:
one or more imaging devices capturing images of at least a portion of the site; and one or more tag devices, each of the one or more tag devices being associated with one of the at least one mobile object and moveable therewith, each of the one or more tag devices having one or more sensors for obtaining one or more tag measurements related to the mobile object associated therewith; and at least one processing structure combining the captured images with at least one of the one or more tag measurements for tracking the at least one mobile object.
