摘要:
A panoramic imaging system is constructed to acquire panoramic images of a very large field of view. The field of view ranges from being nearly hemispherical, to being omni directional with some parts occluded. The panoramic imaging system is comprised of multiple imaging sensors, each imaging different parts of the field of view. The panoramic image is constructed by mosaicing the images taken by different sensors that share a common viewpoint. The resolution across the entire panoramic image is substantially the same. Specific embodiments of the camera provide specific combinations of features, such as different visual fields.

According to one aspect the invention, a panoramic imaging arrangement is provided which includes at least a first lens block including a convex reflective surface and a transparent component. The convex reflective surface has a substantially vertically extending axis of revolution and is capable of receiving light from a 360° surrounding panoramic scene, and reflecting the light for further manipulation. The transparent component covers the convex reflective surface. The convex reflective surface is thereby protected from environmental conditions which may otherwise result in damage to the convex reflective surface.

According to one aspect of the invention there is provided a panoramic imaging arrangement comprising a transparent component and a reflective material. The transparent component has a first surface about a vertical axis of revolution, a second surface about the axis of revolution, and an opening formed therein to define a third, internal surface about the axis of revolution. The third surface has a concave profile in a plane of the axis of revolution. The reflective material is located on the second surface to provide a reflective surface against the second surface. The first surface, the reflective surface and the third surface are positioned relative to one another so that light from a 360° surrounding panoramic scene enters the transparent component through the first surface, whereafter the light is reflected from the reflective surface, whereafter the light exits the transparent component through the third surface.

An aberration-correcting optical relay for an optical system. The relay comprises front and rear converging optical units together with a correcting meniscus or two correcting meniscuses placed symmetrically relative to each other, the meniscus(es) having main faces that are substantially concentric, and preferably exactly concentric, the two converging optical units being placed on a common axis and the correcting meniscus(es) being placed on said axis between the two converging optical units. The front converging optical unit situated upstream from the correcting meniscus(es) is placed in such a manner that the distance from an image point of the portion of the optical system upstream from the optical relay to the front converging optical unit is equal to the focal length of the front converging optical unit, said unit thus transforming a beam coming from said image point into a parallel beam.

According to one aspect of the invention there is provided a panoramic imaging arrangement comprising a first and second transparent component both rotationally symmetric about an axis of revolution. The first transparent component has an upper surface and a lower surface. The lower surface includes a reflective portion and a refractive portion both about the axis of revolution. The refractive portion extends radially from the axis of revolution to the start of the reflective portion. The second transparent component is attached to the first transparent component at a refractive interface that extends into the upper surface. The second transparent component includes a distal reflective surface. Light from a portion of a surrounding panoramic scene is refracted by a portion of the upper surface, is reflected by the reflective portion of the lower surface through the refractive interface to the distal reflective surface. Once reflected from the distal reflective surface, the light again passes through the refractive interface and exits the first transparent component through the refractive portion of the lower surface.

A panoramic imaging lens having an annular light incident surface formed in a substantial convex lens form; a first reflective surface formed in an annular concave mirror form to reflect light inside the lens; a second reflective surface provided at a central part inside the annular light incident surface to reflect the reflected light from the first reflective surface toward an inner part of the annular first reflective surface; and a light outgoing surface positioned at a central part inside the annular first reflective surface and opposing the second reflective surface to transmit light. A non-reflective part exerting no regular reflection of light is provided on a light path toward the light incident surface amongst light paths of light proceeding to agree with a light path of imaging light incident on and refracted at the light incident surface and proceeding inside the lens.

An optical device having a semi-spherical or hemispherical field-of-view is provided. A conically-shaped piece of optical material has an annular surface satisfying Snell's Law for total internal reflection with respect to light passing through the piece and incident on the annular surface from within the piece.

According to one aspect of the invention there is provided a panoramic imaging arrangement comprising lens block and a system of lenses. The lens block has a substantially vertical axis of revolution and is capable of receiving light from a first, 360° surrounding panoramic scene. The system of lenses has a vertical axis of revolution substantially coinciding with the axis of revolution of the lens block and is positioned to receive light from a second scene which is at least partially located above the first, surrounding panoramic scene, and projecting the light from the second scene.
