Abstract
The present invention employs video camera-equipped, unmanned aerial vehicles (UAVs) to collect video imagery from a predefined study area on the ground, where vehicles are performing trips. The video imagery is then processed using machine vision to extract vehicle trajectory information, which is then organized and manipulated for presentation in 5 a user-facing display when required. In contrast with the state of the art data procurement technologies, the resulting data features continuity in both time and space, reflects 100% of the trips and has a significantly lower cost.
Claims16
A process for tracking ground movement, comprising the steps of:
- simultaneously deploying two or more Unmanned Aerial Vehicles (UAVs) to collect ground traffic video imagery, a first UAV equipped with a first camera that collects ground video imagery from a first polygonal coverage area on the ground during a survey period and a second UAV equipped with a second camera that collects ground video imagery from a second polygonal coverage area during the same survey period, wherein the first and second cameras collect video imagery simultaneously during the survey period and the first and second polygonal coverage areas share an edge;
- combining the imagery of the first and second cameras to form a continuous ground video imagery mosaic within which the movement of one or more ground vehicles and/or one or more pedestrians can be tracked with continuity in both time and space.
A system for tracking ground movement of at least one vehicle and/or pedestrian on the ground, comprising a computer system comprising:
- a processor and a non-transitory computer readable medium storing instructions that, when executed by the processor, cause the processor to perform a method comprising the steps of:
- a. accessing aerial ground video imagery taken simultaneously above a first polygonal coverage area and a second polygonal coverage area, wherein the first and second polygonal coverage areas share an edge;
- b. combining the ground video imagery of the first and second polygonal coverage areas to form a continuous ground video imagery mosaic;
- and
- c. tracking the movement of the at least one ground vehicle and/or pedestrian within the first and second polygonal coverage areas, with continuity in both time and space.
