IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND COMPUTER-READABLE RECORDING MEDIUM
First Claim
1. An image processing apparatus comprising:
- a memory; and
a processor coupled to the memory, wherein the processor executes a process comprising;
calculating a coordinate of a first intersection representing an intersection between a stereoscopic projection plane and a line connecting a virtual viewpoint and an intersection between a plane and a line extending downward from a position of an object, and a coordinate of a second intersection representing an intersection between a line extending upward from the first intersection and a line connecting the position of the object and the virtual viewpoint; and
projecting an image of the object to the coordinate of the second intersection.

Abstract
An image processing apparatus includes a coordinate conversion unit and a drawing unit. The coordinate conversion unit obtains a coordinate of an intersection PVG between a stereoscopic projection plane and a line connecting a ground point PRG of a stereoscopic object and a virtual viewpoint position VP, and a coordinate of an intersection PV between a line extending upward from the intersection PVG and a line connecting a point PR of the stereoscopic object and the virtual viewpoint position VP. The drawing unit projects an image of the ground point PRG of the stereoscopic object at the position of the coordinate of PVG, and projects the image of PR of the stereoscopic object at the position of PV.
