摘要:
A multi-temporal, multi-angle, automated target exploitation method is provided for processing a large number of images. The system geo-rectifies the images to a three-dimensional surface topography, co-registers groups of the images with fractional pixel accuracy, automates change detection, evaluates the significance of change between the images, and massively compresses imagery sets based on the statistical significance of change. The method improves the resolution, accuracy, and quality of information extracted beyond the capabilities of any single image, and creates registered six-dimensional image datasets appropriate for mathematical treatment using standard multi-variable analysis techniques from vector calculus and linear algebra such as time-series analysis and eigenvector decomposition.

A method and apparatus for an aircraft monitoring system. The aircraft monitoring system comprises targets associated with the wing of the aircraft, a camera system and a monitor. The camera system is configured to generate images of the targets on the wing during operation of the aircraft. The monitor is configured to measure movement of the targets using images, enabling identifying wing movement.

One or more systems, devices, and/or methods for organizing spatial data are disclosed. For example, a method includes receiving a location data point from a navigation device. A controller compares the distance from each of a plurality of data points to the location data point. In constructing a depthmap that associates each of the data points with the distance from the location data point, the controller assign data points within a minimum distance from the location data point into a first cell and data points greater than the minimum distance from the location data point into a second cell. The second cell is larger than the first cell and corresponds to a larger geographic area than the first cell. The depthmap may be configured to position points of interest in a panoramic or street level view image.

The invention relates to a registration method for detecting the position and orientation of an object or body part (12) relative to a position detection system (10). Said method comprises the following steps: arranging a reference sensor (14) on the object or body part and/or an image sensor unit, detecting the position of the reference sensor (16) by means of the position detection system (10), photogrammetrically detecting a surface of the object or body part (12) and optionally of the reference sensor by means of the image sensor unit, producing a surface model of the object or body part (12) on the basis of photogrammetrically detected information, determining the position of the reference sensor (16) in the surface model, and associating the surface model with a coordinate system of the position detection system (10) using the determined position of the reference sensor (16) in the surface model and the position of the reference sensor (16) detected by means of the position detection system. The invention further relates to a device for carrying out such a method.
摘要:
A method and apparatus are disclosed for localizing a vehicle along a route. The method comprises initially surveying the route to be traversed by the vehicle by creating a plurality of orthographic images of the route, at a plurality of locations along the route and subsequently passing the vehicle along the route while obtaining a current view of the route. The method further comprises resolving a pose of the vehicle relative to a survey trajectory by maximizing a relation between the orthographic images and the current view.
