Abstract:
The purpose of the present invention is to have an operator intuitively and accurately recognize the directionality of an overhead view image whatever the direction in which the overhead view image is displayed may be. The present invention is provided with: multiple cameras (10) in which the obliquely downward direction for capturing the periphery of a dump truck (1) functions as the optical axis; a view point modification unit (22) for generating overhead view images (32) in which the view point of the camera images captured by the cameras (10) are changed to have a top view; an image synthesis unit (25) which arranges a symbol image (31) obtained by symbolizing the dump truck (1) into the center, synthesizes the overhead images (32) in the periphery of the symbol image (31), and generates a synthesized overhead view image; a front icon superimposing unit (24) which superimposes a front icon (33) showing the front direction of the symbol image (31) on the symbol image (31); and a monitor (15) which is provided to the driving chamber (2) of the dump truck (1) and which displays the synthesized overhead view image, in which the front icon (33) was superimposed, in a given direction.
