Document Type and Number:
WIPO Patent Application WO/2013/183536
Kind Code:

Abstract:
The purpose of the present invention is to be able to display as many images as possible of the bottom part of a self-propelled industrial machine that enters the field of view of a camera when an overhead view image is displayed on a monitor using a camera for capturing the periphery of the self-propelled industrial machine. The present invention is provided with: a view point modification unit (22) for generating an overhead view image in which the view point of camera images captured by means of multiple cameras (10) disposed on a dump truck (1) are changed such that the camera images have a top view; a superimposing unit (25) which transmits the lower region of a symbol image (31) as a transmission region (33) and which superimposes regions of the overhead view image (32) corresponding to the transmission region (33) as a lower image (34); an image synthesis unit (26) which sets boundary lines (L1 to L4) for dividing the region displaying each overhead view image (32) on the basis of the transmission region (33) when generating a display image by arranging the symbol image (31) in the center and by synthesizing the overhead view images (32) in the periphery thereof; and a monitor for displaying the image synthesized by means of the image synthesis unit (26).
