  • Patent number: 10404915
    Abstract: Panoramic imaging systems and techniques are disclosed. In one aspect, a technique for generating a stabilized panoramic video image output based on raw image data captured by a panoramic imaging system includes the steps of: receiving raw video images capturing by the panoramic imaging system which is integrated with a set of position sensors; receiving multiple sets of sensor signals acquired by the set of position sensors concurrently when the raw video images are being captured; processing the multiple sets of sensor signals to determine unwanted position changes of the panoramic imaging system when the raw video images are being capturing; and performing an image stabilization operation on the received raw video images to compensate for the effects of the unwanted position changes, thereby generating stabilized panoramic video images based on the raw video images.

  • Patent number: 10390007
    Abstract: Panoramic three-dimensional (3D) imaging systems for capturing stereoscopic video images and presenting 3D video images to a viewer based on the captured stereoscopic video images are disclosed. In some embodiments, the described systems use a proposed parallax vector to encode captured stereoscopic video images in real-time when the raw video images are being captured. During panoramic video playback, the computed parallax vectors are used to reproduce stereoscopic video images based on the angle of view of an audience relative to a display screen before outputting the stereoscopic video images to the left and right eyes of the audience to create the realistic 3D experience.

A candidate set of items may be identified based at least in part on a selection model. In accordance with at least one embodiment, the selection model may be based at least in part on a capacity of the storage location and a threshold time duration by which purchased items of the set of items are to be transported from the storage location to a purchaser. A plurality of probability values corresponding to the candidate set of items may be determined. An optimal set of items may be determined based at least in part on the candidate set of items and the plurality of probability values.

  • Patent number: 10148875
    Abstract: Panoramic imaging systems and process for multiplexing a set of video signal inputs captured by a set of cameras in a panoramic imaging system into a single video signal output is disclosed. In some embodiments, the disclosed process receives a set of input image frames associated with the set of video signal inputs and temporarily stores the set of input image frames in a memory. Next, for each pair of image frames in the set of input image frames, the process iteratively processes each line in the pair of image frames to construct a portion of a video signal output frame. The process then combines portions of the video signal output frame to form a single composite output frame containing the image data of the set of input image frames.
