As the commercial drone market expands at an accelerating rate, so does the risk of malicious use of these devices and the need to successfully detect and take counter measures. This is the focus of the most recent PureTech Systems patent approval. System and Method for Autonomous PTZ Tracking of Aerial Targets (US Patent No 9,652,860 B1), grants claims for video-based detection and tracking of targets against a featureless background, such as airborne aircraft and drones. The patent leverages the PureTech?s continued research and development using geospatial video analytics for both security and safety applications.
