Abstract: A plurality of images captured by a plurality of cameras respectively to create a plurality of upper viewpoint images. Display images are extracted from the upper viewpoint images, and the extracted display images are synthesized to create an overhead image or bird's eye view image of surroundings, which has an image corresponding to an operating machine at a center of the bird's eye view image. When extracting each of the display images, a region of the display image extracted from the upper viewpoint image is expanded beyond the size of a standard extraction region on the basis of the set height of a mating face. Each of the extracted display images is adjusted to the size of the standard extraction region, and synthesized. Thus, any three-dimensional object (obstacle) present near the boundary between display images constituting the bird's eye view image is displayed.

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.

Abstract: The underneath image of a self-propelled industrial machine is displayed with as wide a range as possible on a monitor with cameras that take images around the self-propelled industrial machine in the form of bird's eye view images. A view point conversion section creates the bird's eye view image by converting images from plural cameras provided on a dump truck; and a superposing process section processes the images to make the underneath area in a symbol image a transparent region corresponding to the position in the bird's eye view. An image composing section sets the symbol image at the center position and the respective bird's eye view images around the symbol image. A monitor displays the composite image composed by the image composing section.

Abstract: Provided is a navigation system for autonomous dump trucks capable of preventing a dump truck from autonomously traveling on a carrying passage differing from the actual carrying passage even when the carrying passages for the dump truck have been altered. The navigation system is based on map data created by digitizing a map of roads on which the dump truck can travel. A control unit executes switching control between an autonomous mode to be selected when the autonomous traveling of the dump truck should be performed and a maneuver mode to be selected when the dump truck should travel according to an operator, based on version information of the map data used by the dump truck for the autonomous traveling and version information of master map data created by digitizing a map of the latest roads on which the dump truck can travel, managed by a control center.

Abstract: A surroundings monitoring device (200) provided on machinery which changes its vehicle body height. The surroundings monitoring device includes a plurality of cameras (30) that image the surroundings thereof, a unit for converting the original images (31) taken by the cameras (30) to overhead viewpoint images (35), a unit for combining the overhead viewpoint images (35) to generate a bird's-eye image (300), a unit for displaying the bird's-eye image (300), and a unit for detecting the positions of the cameras. The bird's-eye image-generating unit adjusts the display region (e) for each overhead viewpoint image (35) on the basis of the detected height of the camera concerned, and combines the overhead viewpoint images. It is therefore possible to always generate and display an accurate bird's-eye image (300) even when the vehicle body height changes significantly.
