Image generating method

摘要

An image generating method includes: generating first and second projected two-dimensional images of a front object seen from first and second viewpoints, the front object being a part of the three-dimensional image divided by a predetermined boundary surface; interpolating the first and second projected two-dimensional images to generate a first interpolated two-dimensional image of the front object seen from a third viewpoint locating on a straight line connecting the first and second viewpoint; generating third and fourth projected two-dimensional images of a rear object seen from the first and second viewpoints, the rear object being another part of the three-dimensional image divided by the predetermined boundary surface; interpolating the third and fourth projected two-dimensional images to generate a second interpolated two-dimensional image of the rear object seen from the third viewpoint; and overwriting the first interpolated two-dimensional image on the second interpolated two-dimensional image.

1. An image generating method, executed by an image generator, for generating a projected two-dimensional image of a three-dimensional image seen from a view point located in a coordinate system including the three-dimensional image, the three-dimensional image being stored in a storage, the image generating method comprising:
generating, by the image generator, first and second projected two-dimensional images of a front object seen from first and second viewpoints, the front object being a part of the three-dimensional image divided by a predetermined boundary surface; interpolating, by the image generator, the first and second projected two-dimensional images to generate a first interpolated two-dimensional image of the front object seen from a third viewpoint locating on a straight line connecting the first and second viewpoint; generating, by the image generator, third and fourth projected two-dimensional images of a rear object seen from the first and second viewpoints, the rear object being another part of the three-dimensional image divided by the predetermined boundary surface; interpolating, by the image generator, the third and fourth projected two-dimensional images to generate a second interpolated two-dimensional image of the rear object seen from the third viewpoint; and generating a composite image by overwriting the first interpolated two-dimensional image on the second interpolated two-dimensional image by the image generator, the composite image being based on each of the first and second two dimensional images of the front object, the first interpolated two-dimensional image, the third and fourth projected two-dimensional images of the rear object, and the second interpolated two-dimensional image, wherein the front object and the rear object are statically arranged with respect to each of other and the generation of the composite image prevents an omission of a part of the rear object within the composite image from occurring when the part of the rear object is in a dead angle from both the first and second viewpoints.
