Image processing apparatus, image processing method, and computer-readable recording medium

摘要

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.

1. An image processing apparatus comprising:
a memory; and a processor coupled to the memory, wherein the processor executes a process comprising: measuring a top position of an object using a range sensor, the object located outside of a stereoscopic projection plane; calculating a coordinate of a first intersection (PVG) representing an intersection between the stereoscopic projection plane and a first line connecting a virtual viewpoint and an intersection (PRG) between a plane and a line extending downward from the top position of the object, and a coordinate of a second intersection (PV) representing an intersection between a line extending upward from the first intersection (PVG) and a line connecting the top position of the object and the virtual viewpoint, an angle between the first line and a second line is a predetermined angle, the second line being a line that extends vertically downward from the top position of the object; and projecting an image of the object to the coordinate of the second intersection (PV).
