  • Publication number: 20230252599
    Abstract: Each image in a sequence of images includes three-dimensional locations of object features depicted in the image, and a first camera position of the camera when the image is captured. A gap is detected between first camera positions associated with a first continuous and first camera positions associated with a second continuous subset, the first camera positions associated with the second continuous subset adjusted to close the gap. A view path for a virtual camera is determined based on the first camera positions and the adjusted first camera positions. Second camera positions are determined for the virtual camera, for each of the second camera positions: one of the first camera positions associated with the sequence of images is selected and warped using the first camera position, the second camera position, and the three-dimensional locations of object features depicted in the selected image. A sequence of the warped images is outputted.

  • Patent number: 11651473
    Abstract: In one embodiment, a method includes generating an outputted sequence of warped images from a captured sequence of images. Using this captured sequence of images, a computing system may determine one or more three-dimensional locations of object features and a corresponding camera position for each image in the captured sequence of images. Utilizing the camera positions for each image, the computing system may determine a view path representing the perspective of a virtual camera. The computing system may identify one or more virtual camera positions for the virtual camera located on the view path, and subsequently warp one or more images from the sequence of captured images to represent the perspective of the virtual camera at each of the respective virtual camera positions. This results in a sequence of warped images that may be outputted for viewing and interaction on a client device.
