Abstract: Designs for a light field otoscope are disclosed. An example light field otoscope includes an objective lens group, relay optics and a plenoptic sensor (e.g., microlens array and sensor array). The objective lens group images an interior of a human ear and is characterized by a pupil plane and an image plane. The relay optics is positioned between the objective lens group and the plenoptic sensor. It relays the image plane to the microlens array and relays the pupil plane to the sensor array.

Abstract: The disclosure includes a system and method for calibrating a binocular optical see-through augmented reality display. A calibration application renders one or more images of a virtual object on the one or more displays of the human interface device, and receives a user input to adjust a position of the one or more images on the one or more displays. In response to the input, the calibration application identifies a first and second boundary of a target range surrounding a real-world object at a first and second depth, respectively. The calibration application determines a first and second disparity corresponding to the first and second boundary and may record the disparities in relation to the depth of the real-world object.

Abstract: Light field images of a three-dimensional scene are transformed from an (image,view) domain to an (image,scale,depth) domain. Processing then occurs in the (image,scale,depth) domain.

Abstract: The pupil image function (PIF) matrix of a plenoptic imaging system is calibrated, taking advantage of the low rank of the PIF matrix. In one approach, the low rank is utilized by identifying a subspace for the PIF matrix and then estimating the PIF matrix within that subspace. This can lead to a significant reduction in the number of calibration patterns used to estimate the PIF matrix.

Abstract: The disclosure includes a system and method for calibrating a binocular optical see-through augmented reality display. A calibration application renders a virtual object to overlay and align with a real-world object on the display, receives a depth between the real-world object and the eyes of the user, receives user input to move the virtual object on the display for depth-disparity calibration, and determines a mapping between the depth and the disparity.
