A method that enables creation of a 3D virtual reality environment from a series of 2D images of a scene. Embodiments map 2D images onto a sphere to create a composite spherical image, divide the composite image into regions, and add depth information to the regions. Depth information may be generated by mapping regions onto flat or curved surfaces, and positioning these surfaces in 3D space. Some embodiments enable inserting, removing, or extending objects in the scene, adding or modifying depth information as needed. The final composite image and depth information are projected back onto one or more spheres, and then projected onto left and right eye image planes to form a 3D stereoscopic image for a viewer of the virtual reality environment. Embodiments enable 3D images to be generated dynamically for the viewer in response to changes in the viewer's position and orientation in the virtual reality environment.

The present invention provides a novel imaging system for obtaining full stereoscopic spherical images of the visual environment surrounding a viewer, 360 degree both horizontally and vertically. Displaying the images obtained by the present system, by means suitable for stereoscopic displaying, gives the viewers the ability to look everywhere around them, as well as up and down, while having stereoscopic depth perception of the images displayed images. The system according to the present invention comprises an array of cameras, wherein the lenses of said cameras are situated on a curved surface, pointing out from common centers of said curved surface. The captured images of said system are arranged and processed to create sets of stereoscopic image pairs, wherein one image of each pair is designated for the observer right eye and the second image to his left eye, thus creating a three dimensional perception.

The present invention tracks a specified target object and provides an image in real time in a way that gives a viewer a sense of reality. The present invention connects, in order to produce a spherical image Q1, the images captured by cameras 13 that can move in a space and are arranged so as to take images of different directions such that the images captured by at least two or more image pickup elements are partially overlapped with one another, calculates a positional correlation between the spherical image Q1 and the target object specified from the images, and then arranges the target object substantially at the center of the spherical image Q1 in accordance with the positional correlation. This provides a tracking image that tracks and focuses on the target object out of the spherical image Q1.
