Abstract
Described are methods and systems for collision avoidance in an underground mine environment that use one or more of a computer vision component, an asset tracking system, and a motion detection component for the purpose of determining and responding to potential collision threats. Imaging is captured and processed in real time, so that assets of interest can be identified and used in evaluating potential for collision with other assets. Location data from an asset tracking system is likewise evaluated and used to determine proximity of assets in relation to the host. A final input is provided by the motion detection component that intelligently determines movement patterns and direction of travel. Once these components' inputs are collectively evaluated, a proximity or a threat value is generated which determine an audible or visual signal or action to prevent collision and increase safety in unfavorable conditions.
