Image generating apparatus, synthesis table generating apparatus, and computer readable storage medium

摘要

An image generating apparatus includes an image receiving unit, a projecting unit, and a panoramic image generating unit. The image receiving unit receives camera images captured by a plurality of cameras, the subject of which is common. The projecting unit projects, within each camera image received by the image receiving unit, images which are present below the horizontal line within each camera image on the bottom surface of an infinite hemisphere having a planar bottom surface and projects images which are present above the horizontal line within each camera image on the hemispherical surface of the infinite hemisphere. The panoramic image generating unit generates a panoramic image based on the images projected on the infinite hemisphere by the projecting unit.

1. An image generating apparatus comprising:
a processor; and a memory, wherein the processor executes:
receiving a plurality of camera images captured by each of a plurality of cameras having a common subject;generating a virtual spherical screen whose center is set to a position corresponding to an eye line of a driver of a vehicle to which the plurality of cameras is mounted and calculating a z-component of a unit direction vector of a segment connecting the center of the spherical screen and a position of a subject captured in each of the camera images;projecting, within each of the camera images received at the receiving, an image for which the calculated z-component is negative and which is present below a predetermined horizontal line within each of the camera images on a planar bottom surface of an infinite hemisphere having the planar bottom surface, and an image for which the calculated z-component is positive and which is present above the horizontal line within each of the camera images on a hemispherical surface of the infinite hemisphere; andgenerating a panoramic image including a common area of the camera images by using the images projected on the hemispherical surface and the planar bottom surface of the infinite hemisphere having the planar bottom surface at the projecting.
