Application: Depth information based pose determination for mobile platforms, and associated systems and methods (Patent ID: US20230376106A1)
The patent filed by SZ DJI Technology Co Ltd describes a method for determining the depth range where a subject is likely to appear in a current depth map based on previous depth maps, filtering the map, identifying candidate regions, selecting a subset, determining main and target regions, identifying pose components of the subject, and controlling a movable object based on spatial relationships. The method involves processing depth data obtained from images captured by a stereo camera on the movable object, with the subject being a human and the pose components representing different body parts. The system can be applied to various movable objects like UAVs, autonomous cars, robots, and wearable devices, enabling precise movement control based on subject detection and spatial relationships.
The patent also includes claims for a movable object equipped with a controller programmed to implement the method described, utilizing a stereo camera to generate depth data and control movement based on identified pose components and spatial relationships. The system can handle unknown or inaccurate depth information and is applicable to a range of movable objects like UAVs, robots, and VR/AR headsets. The method involves detecting specific body parts of the subject based on depth measurements and controlling movement based on the identified spatial relationships, ensuring accurate and efficient interaction between the movable object and the subject in various environments.
