  • Publication number: 20100165105
    Abstract: A projection model storage section stores position information of a plurality of points on a predetermined projection model. A computation section references the projection model storage section and acquires position information of a virtual image correspondence point of a point corresponding to a pixel of the virtual image in an area on the projection model specified as a target of the virtual image by an output range specification section. The computation section finds the pixel of a real image corresponding to the virtual image correspondence point, acquires a mapping table indicating the correspondence between the pixels of the virtual image and the pixels of the real image, and records the mapping table in a mapping table storage section. An image synthesis section references the mapping table storage section and converts an image input from an image pickup section into a virtual image viewed from a predetermined virtual eye point.

  • Patent number: 7502048
    Abstract: The invention provides a vehicle surroundings monitoring system for synthesizing and displaying images captured by a plurality of cameras to provide images that, near the border between partial images, are more accurate and more readily understood by the user than has been the case conventionally. In the synthesized image, a partial image captured by a first camera and a partial image captured by a second camera are adjacent to one another at their border. Near this border, the capturing directions of the first and the second cameras both substantially match the direction of the border. Consequently, images of objects near the border extend along the border, and thus do not disappear on the synthesized image.
