Abstract: A method and system for synchronization of image data is provided. A plurality of image-capture devices is controlled to acquire a plurality of video clips of at least one object. Each video clip of the plurality of video clips is acquired by a corresponding image-capture device of the plurality of image-capture devices in a moving state. From the plurality of image-capture devices, a set of sensor data is acquired. Such data corresponds to the plurality of image-capture devices and is associated with a movement of the plurality of image-capture devices. Thereafter, relative offsets between the set of sensor data are determined by using cross-correlation and matching frames in each of the plurality of video clips is further determined, based on the relative offsets.

Abstract: A minimal volumetric 3D transmission implementation enables efficient transmission of a 3D model to a client device. A volumetric 3D model is generated using a camera rig to capture frames of a subject. A viewer is able to select a view of the subject. A system determines an optimal subset of cameras of the camera rig to utilize to capture frames to generate the volumetric 3D model based on the viewer's selected view. The volumetric 3D model is transmitted to the user device. If the user changes the view, the process repeats, and a new subset of cameras are selected to generate the volumetric 3D model at a different angle.
