Methods to warn proximate entities of interest and system for warning a forktruck operator

摘要

Systems and methods to detect and warn proximate entities of interest are described herein. In some examples, a trajectory vector is generated for at least two entities of interest based on at least one characteristic of movement of each entity. Each entity's trajectory vector is expanded and each entity's expanded trajectory vector is analyzed for overlap with the other entity's expanded trajectory vector to assess the possibility of a collision between them.
