  • Publication number: 20220408019
    Abstract: A set of images may be captured by a camera as the camera moves along a path through space around an object. Then, a smoothed function (e.g., a polynomial) may be fitted to the translational and/or rotational position in space. For example, positions in a Cartesian coordinates pace may be determined for the images. The positions may then be transformed to a polar coordinate space, in which a trajectory along the points may be determined, and the trajectory transformed back into the Cartesian space. Similarly, the rotational position of the images may be smoothed, for instance by fitting a loss function. Finally, one or more images may be transformed to more closely align a viewpoint of the image with the fitted translational and/or rotational positions.
