Abstract
A bird's eye view image is displayed to be recognized by an operator intuitively and precisely, irrespective of the displayed direction of the bird's eye view image. The display device has a plurality of cameras having optical axis directed obliquely downward to take images around a self-propelled industrial machine. A view point converting section converts the camera images to an upper view point to create bird's eye images, and an image composing section creates a composite bird's eye view image by composing respective bird's eye images around a symbol image of a dump truck. A direction superposing section superposes a forward direction indicator to indicate the forward direction of the dump truck on the composite bird's eye view image, and a monitor mounted in a cab of the dump truck displays the composite bird's eye image in an arbitral direction which is composited with the forward direction indicator.
