Abstract:
A Method for generating scaled terrain information while operating a bulldozer. The bulldozer may include a driving unit comprising a set of drive wheels, a motor connected to at least one of the drive wheels, a blade for altering the surface of the terrain, at least one camera for capturing images of the environment, the camera being positioned and aligned in a known manner relative to the bulldozer, and a controlling and processing unit. A method may include moving the bulldozer while concurrently generating a set of image data by capturing an image series of terrain sections with the at least one camera so that at least two images of the image series cover an amount of identical points in the terrain, and either applying a simultaneous localization and mapping (SLAM) algorithm or a stereo photogrammetry algorithm to the set of image data and thereby deriving terrain data.
Abstract:
Provided is a computer system and method for providing key frame image mapping. A method includes collecting one or more images of a predetermined area on the map of a physical location; and organizing the one or more images on the map as a function of a time, location, and/or image history parameter. A computer system includes a mapping module including a data store configurable to organize one or more images according to locations on a map and a table. The table can associate metadata for images with a time line, an image history and/or a location. The association can enable an instantiation of a time-related image from images at locations of the map. The mapping module enables a personalized iconographic map of a physical location illustrating icons associated with a catalog of images that are incorporated with the time line. The time line can be associated with a trip taken to an area in a map such that scrolling the time line automatically causes images associated with that time appear as well as the location on the map wherein the picture was taken.
Abstract:
A three-dimensional range camera, which produces a range map of the distances from a reference to each of M.times.N points in a scene, is modified to generate registered luminance and range images. The same sensor detects range and luminance variations. A planar pattern projector generates sequential presentations of time/space coded light rays which are projected onto the object. A linear array camera images the points of light on the object surface, and a processor analyzes one-dimensional scan signals to determine range. To detect luminance there is an additional presentation, either constant illumination or no artificial illumination, and the other scan signal yields luminance along the same strip of the scene.
Abstract:
One aspect of the invention relates to a fully automatic method for calculating the current, geo-referenced position and alignment of a terrestrial scan-surveying device in situ on the basis of a current panoramic image recorded by the surveying device and at least one stored, geo-referenced 3D scan panoramic image.
Abstract:
Embodiments of a method and system for sensing an obstacle, a computer device, and a computer-readable storage medium are provided. The method can include: capturing continuously, by first and second cameras adjacently arranged on a motor vehicle, obstacles around the motor vehicle, to obtain at least a first obstacle image and a second obstacle image respectively; associating the first obstacle image with the second obstacle image; determining whether the first obstacle image and the second obstacle image comprise the same obstacle. By means of some of the disclosed methods and systems, an obstacle can be real-time sensed by a motor vehicle in a large field of view, such as, a range of 360° around the vehicle.
Abstract:
A Position and Orientation Measurement Engine (POME) is a mobile camera system that can be used for accurate indoor measurement (e.g., at a construction site). The POME uses a plurality of cameras to acquire images of a plurality of targets. If locations of the plurality of targets are precisely known, images of the targets can be used to determine a position of the POME in relation to the plurality of targets. However, to precisely determine locations of the plurality of targets can be time consuming and/or use expensive equipment. This disclosure discusses how to use a camera system with an electronic distance measuring unit to determine locations of the plurality of targets.

Abstract:
A method of targeting a missile. A plurality of images of a target, taken from a plurality of viewpoints, are received. Features in the images characteristic of the target are identified. Data representing the characteristic features are provided to the missile to enable the missile to identify, using the characteristic features, the target in images of the environment of the missile obtained from an imager included in the missile.

Abstract:
A distance measuring apparatus includes: an acquisition unit that acquires a first image at a first viewpoint where an object is irradiated with a first light including a pattern, a second image at a second viewpoint different from the first viewpoint where the object is irradiated with the first light, a third image at the first viewpoint where the object is irradiated with a second light not including a pattern, and a fourth image at the second viewpoint where the object is irradiated with the second light; and a control unit that acquires information corresponding to a distance, by employing a fifth image obtained based on a ratio the first image and the third image and a sixth image obtained based on a ratio of the second image and the fourth image.
