  • Publication number: 20230306640
    Abstract: A method of 3D motion reconstruction of outdoor, highly flexible moving subjects with multiple cameras on drones is described herein. A multi-drone capturing system is used to remove the restriction of a dedicated virtual reality shooting place, “the hot seat,” so that the actor/target is able to perform agile or long-distance activities outdoor. The subject's 3D pose parameters are estimated by the captured multi-view images by the drones, and the sequence of poses becomes the motion in time to control the animation of a pre-built 3D model. The method is able to be directly integrated into an existing Virtual Reality/Augmented reality (VR/AR) production chain, and the subject is able to be extended to animals that are difficult to be contained in a VR camera mesh space.

  • Patent number: 11721030
    Abstract: A method for optimizing image capture of a scene by a swarm of drones including a root drone and first and second level-1 drones involves the root drone following a predetermined trajectory over the scene, capturing one or more root keyframe images, at a corresponding one or more root drone orientations and root drone-to-scene distances. For each root keyframe image: the root drone generates a ground mask image for that root keyframe image, and applies that ground mask image to the root keyframe image to generate a target image. The root drone then analyzes the target image to generate first and second scanning tasks for the first and second level-1 drones to capture a plurality of images of the scene at a level-1 drone-to-scene distance smaller than the root drone-to-scene distance; and the first and second level-1 drones carry out the first and second scanning tasks respectively.

  • Publication number: 20220398395
    Abstract: A method for removing extraneous content in a first plurality of images, captured at a corresponding plurality of poses and a corresponding first plurality of times, by a first drone, of a scene in which a second drone is present includes the following steps, for each of the first plurality of captured images. The first drone predicts a 3D position of the second drone at a time of capture of that image. The first drone defines, in an image plane corresponding to that captured image, a region of interest (ROI) including a projection of the predicted 3D position of the second drone at a time of capture of that image. A drone mask for the second drone is generated, and then applied to the defined ROI, to generate an output image free of extraneous content contributed by the second drone.

The second plurality of drones moves to track target movement of the target, with drone camera poses determined at least in part by the head pose and gaze determinations received from the first plurality of drones, in order to capture a second plurality of images of portions of the environment in front of the target. Post-processing of the second plurality of images allows generation of a first-person view representative of a view of the environment seen by the target.

  • Patent number: 11256257
    Abstract: A method of camera control for a camera capturing images of a target includes a sequence of at least four steps. The first step determines in real time a location of a drone and a pose of a camera on the drone. The second step, which may occur before or after the first step, determines in real time a location of a reference object, the location of the reference object having a fixed relationship to a location of the target. The third step uses the determined locations to calculate a distance, characterized by magnitude and direction, between the target and the drone. The fourth step uses the calculated distance to control the pose of the camera such that an image captured by the camera includes the target. Controlling the pose of the camera does not require any analysis of the captured image.
