To enable an image with no blind spot area to be obtained while ensuring a wide field of view, an omnidirectional imaging system includes: a primary mirror () including a hyperbolic mirror; a plurality of secondary mirrors () arranged around the primary mirror and each including a hyperbolic mirror; and a camera () that captures an image reflected by the primary mirror and images reflected by the plurality of secondary mirrors. A hyperboloid of the primary mirror and hyperboloids of the plurality of secondary mirrors have a substantially coincident outer focal point, and the camera () is placed so that a viewpoint of the camera substantially coincides with the outer focal point of the hyperboloid of the primary mirror () and the hyperboloids of the plurality of secondary mirrors (), the viewpoint of the camera being an entrance pupil position of a lens attached to the camera ().

Omnidirectional imaging system

A position measuring apparatus which measures a position of a position measurement target easily and accurately without using any parameter inside a camera in the measurement, based on images captured from mutually different viewpoints. The position measuring apparatus which measures the three-dimensional position of the position measurement target, based on the input images captured from the mutually different viewpoints, and the position measuring apparatus includes: a ray information storage unit configured to store ray information in which each of ray vectors is associated with a corresponding one of pixels in one of the input images, each of the ray vectors indicating a forward direction of a light incident onto an optical system for a corresponding one of the input images; and a position measuring unit configured to measure the three-dimensional position of the position measurement target, using the ray information stored in the ray information storage unit.

Position measuring apparatus, position measuring method, image processing apparatus and image processing method

An image generating apparatus which generates a second image that is an image converted from a first image captured by an imaging apparatus placed to be oriented downward at an angle of depression with respect to a horizontal direction includes: a specifying unit which specifies a straight line included in the first image and passing through an intersection between an imaging plane and a vertical vector; and an image extension processing unit which generates the second image by sampling pixels of the first image along the specified straight line.
