Abstract: A panoramic imaging system includes a convex reflector, a camera, a transparent cylinder for mounting the convex reflector to the camera, and a first radially-oriented planar member positioned in the transparent cylinder between the convex reflector and the camera. A second radially-oriented planar member can be positioned in the transparent cylinder between the convex reflector and the camera. The first and second radially-oriented planar members would preferably lie in perpendicular planes, however, they may lie in non-perpendicular planes. A mirror mount for a panoramic imaging system includes a convex reflector, a transparent cylinder for supporting the convex reflector, means for connecting a camera to the transparent cylinder, and a first radially-oriented planar member positioned in the transparent cylinder between the convex reflector and the camera. A method of reducing unwanted reflections in the panoramic imaging system is also included.

Abstract: A method for eliminating unwanted portions of an image comprising the steps of generating a panoramic image including a plurality of image pixels, identifying a first set of the image pixels that correspond to the unwanted portions of the image, determining particular characteristics of the image pixels positioned adjacent to the image pixels in the first set of image pixels, and replacing the first set of image pixels with replacement pixel data generated by using the particular characteristics of the image pixels adjacent to the first set of image pixels. The replacement pixel data can be generated by interpolating or extrapolating pixel data from the image pixels positioned adjacent to the image pixels in the first set of image pixels. A panoramic photographic system that operates in accordance with the above method is also included.

Abstract: The present invention relates to the capture and playback of directional sound in conjunction with selected panoramic visual images to produce an immersive experience.

Abstract: A mining machine having a position sensing and control apparatus is claimed. The mining machine has a vehicle body having forward and rearward ends and movable along a mine floor. A cutter head is mounted on the forward end of the mining machine for upward and downward movement relative to the vehicle body. A conveyor mounted on the vehicle body conveys material cut by the cutter head. The position sensing and control apparatus has at least one light source and at least one imaging device mounted on the machine. The position sensing and control apparatus captures images of natural features of an interior surface of a mine, digitizes the images and determines the distance between the imaging device and the natural feature to determine positional change of the machine.

Abstract: A mining machine comprising a vehicle body having forward and rearward ends, the vehicle body being movable along a mine floor, a cutter head mounted on the forward end of the vehicle body, and a position sensing and control apparatus including first and second generally vertical, generally parallel surfaces on the vehicle body, an off-board light source emitting a light beam that strikes the surfaces, an imaging device for imaging both of the plates in a single image, and a computer receiving the single image from the camera, the computer using the single image to determine at least one of the roll, yaw and lateral offset of the machine.
