PROCESSING-TARGET IMAGE CREATING DEVICE, PROCESSING-TARGET IMAGE CREATING METHOD, AND OPERATION ASSISTING SYSTEM

摘要

A processing-target image creating device creates a processing-target image based on a plurality of input images. The processing-target image creating device includes a coordinates-associating part configured to associate coordinates on each input image plane on which each input image is positioned, coordinates on a space model onto which each input image is projected, and coordinates on a processing-target image plane, and an. image adjusting part configured to adjust the processing-target image by determining for each input image a re-projection angle of a re-projection line joining the coordinate and the coordinate. The image adjusting part determines for each input image slopes of the re-projection lines such that each coordinate on the processing-target image plane corresponding to an infinity line in each input image corresponds with each other on a dividing line between image parts corresponding to each input image on the processing-target image plane.

1. A processing-target image creating device configured to create a processing-target image subjected to an image conversion process for obtaining an output image based on a plurality of input images captured by a plurality of cameras, comprising;
a coordinates-associating part configured to associate coordinates on each input image plane on which each input image is positioned, coordinates on a space model onto which each input image is projected, and coordinates on a processing-target image plane on which the processing-target image is positioned and onto which an image projected on the space model is re-projected; an image adjusting part configured to adjust the processing-target image by determining for each input image a slope of a straight line joining a coordinate on the space model and a coordinate on the processing-target image plane corresponding to the coordinate on the space model, wherein the coordinates-associating part associates the coordinate on the space model with the coordinate on the processing-target image plane such that each of the straight lines relating to one input image becomes parallel to one another on a plane perpendicular to the processing-target image plane, or associates the coordinate on the space model with the coordinate on the processing-target image plane such that each of the straight lines relating to one input image passes through a single predetermined point, and wherein the image adjusting part determines for each input image slopes of the straight lines such that each coordinate on the processing-target image plane corresponding to an image representing a predetermined feature in each input image corresponds with one another on a dividing line between image parts corresponding to each input image on the processing-target image plane.
