Automatic Real-time, Identification, Acquisition and Tracking of Targets
Vector™ is a proprietary, high-performance embedded computing platform that is dedicated to real-time advanced video processing. Vector is an optional solution that is onboard select Aeryon SkyRanger payloads, including the SR-EO/IR Mk II and HDZoom30.
Vector is built upon the NVIDIA TK1 chip set which provides a quad-core 2.2 GHz processor and a dedicated GPU, embedded in the payload. The image processing capabilities provide the automatic identification and tracking of moving targets. Pilots can also maintain a fixed hold on stationary objects while the aircraft is repositioned.
As well, the tracking algorithm adapts in real-time to changes in target shape and maintains a hold on the target even when its position changes or another object obstructs the view.
Initial features include:
- Target Tracker: Automatically, identifies and holds a stationary or moving target centrally in the field of view (FoV) of the camera by repointing the camera and yawing the aircraft
- Moving Target Indicator (MTI): Pilots can visually annotate up to 10 moving objects within the FoV
- Digital Image Stabilization (DSI): Onboard video stabilization which is in addition to the stabilization from the gimbal
Target Tracker automatically maintains a lock on a target even as the appearance of the target changes. For example, as a vehicle turns 90 degrees and the view shifts from the side of the vehicle to the narrowed aspect of the rear view, the tracker “learns” in real-time.
Vector also provides the foundation for applications to interoperate seamlessly, for example the transition from MTI to Target Tracker of a single identified object (as shown below).
Additionally, by running advanced video processing on the aircraft vs on the ground, latency in the control chain is minimized.
Benefits for Public Safety Applications
MTI automatically highlights what is moving in the video feed to reduce the effort on the pilot, allowing him/her to focus on other tasks.
Example: For a Tactical/SWAT unit using Aeryon sUAS in a hostage/armed-suspect scenario, MTI will automatically annotate movement around the building, such as the escape of the suspect. This capability would otherwise be left to the pilot or remote viewers to visually identify movement on the Mission Control Station (MCS) or through AeryonLive.
Target Tracker enables a pilot to track a stationary or moving object in the video feed which reduces the time and effort to perform the task manually.
Example: In a covert mission, a public safety agency might have a vehicle or person under surveillance at a long range. Manually pointing the camera at long range and extended zoom levels can be challenging. Losing the target may mean missing a critical action or interaction, such as dropping an object. Target Tracker automates the task of pointing the camera and enables the pilot to focus on visually analyzing the video feed and other aspects of the mission.
Benefits for Commercial Applications
Target Tracker can be used to reduce the ‘effort’ needed to control the payload enabling the operator to simply click on objects to centre them in the camera’s field of view, etc. rather than trying to do it manually.
Example: Cell tower inspection, the pilot clicks on the antenna to activate target and it remains centered in the camera’s field of view
