Abstract: A system and method are presented for estimating the orientation of a panoramic camera mounted on a vehicle relative to the vehicle coordinate frame. An initial pose estimate of the vehicle is determined based on global positioning system data, inertial measurement unit data, and wheel odometry data of the vehicle. Image data from images captured by the camera is processed to obtain one or more tracks, each track including a sequence of matched feature points stemming from a same three-dimensional location. A correction parameter determined from the initial pose estimate and tracks can then be used to correct the orientations of the images captured by the camera. The correction parameter can be optimized by deriving a correction parameter for each of a multitude of distinct subsequences of one or more runs. Statistical analysis can be performed on the determined correction parameters to produce robust estimates.

Abstract: Optical systems utilize waveplates to simultaneously encode information for increasing image depth of field and for providing a depth map of the imaged object or sample. These waveplates are configured to result in a focus-invariant point spread function in one focal region, and to result in point spread functions that vary as a function of range within the imaged object in a different focal region.

An image formed on one side of the plane of best focus is focus invariant, and is brought into focus by a restoring algorithm. An image formed on the other side of the plane of best focus captures point spread functions comprising rings that vary with depth within the imaged object.
