Image generation apparatus for generating an image for enlarged display of the mobile and structures on the road existing in distant view side of the captured image, to provide an image generating method and a computer program.
Road acquires the captured image captured and the image generating apparatus for generating an image showing the situation on the road based on the acquired captured images, converging from the acquired captured images, the vanishing point in the depth direction of the captured image 2 deforming the vanishing line of the present, a region extracting means for extracting an image of a trapezoidal area each is surrounded by two parallel straight lines intersecting the two vanishing line, a trapezoidal area region extracting means has extracted rectangular area using geometric transformation model expansion, conversion means for converting the image of the trapezoidal area in the image of the rectangular area, and based on the image of the converted rectangular area, the moving body or structure on the road existing in distant view side of the captured image It comprises generating means for generating an image to be displayed.
