The present invention discloses a new type of method, apparatus and computer program for reconstructing a stereoscopic panoramic image. In the invention, the stereopanoramic image is generated by combining an image sequence and a separate panoramic image. In a preferred embodiment, the image sequence covers 360 degrees, as does the panoramic image. In the method, the time-lapse camera which stores the image sequence is moveable about a navel point at a fixed distance. The panoramic camera, on the other hand, is positioned at the navel point. The first image sequence is stored by moving the camera about the navel point, the camera being oriented, at each moment of exposure, to a direction that is tangential to the trajectory of the camera. The second panoramic image sequence can be stored by also moving the camera about the navel point, the camera being, this time, oriented to a direction that is tangential to the trajectory of the camera and opposite to the previous direction. Finally, an individual stereo pair of the stereopanoramic image is generated by combining part of the panoramic image and an individual image from the image sequence. The stereopanoramic image can be formed of a set of adjacent stereo pairs. In one embodiment, rays of light can be deflected using reflecting and/or refracting elements. The surrounding scene can also be examined by measuring it with a laser scanner, and the measurement data can be further modified based on the viewing properties of the stereopanoramic image. |
