Abstract: A method for extracting a 3D terrain model for identifying at least buildings and terrain from LIDAR data is disclosed, comprising the steps of generating a point cloud representing terrain and buildings mapped by LIDAR; classifying points in the point cloud, the point cloud having ground and non-ground points, the non-ground points representing buildings and clutter; segmenting the non-ground points into buildings and clutter; and calculating a fit between at least one building segment and at least one rectilinear structure, wherein the fit yields the rectilinear structure with the fewest number of vertices. The step of calculating further comprises the steps of (a) calculating a fit of a rectilinear structure to the at least one building segment, wherein each of the vertices has an angle that is a multiple of 90 degrees; (b) counting the number of vertices; (c) rotating the at least one building segment about an axis by a predetermined increment; and (d) repeating steps (a)-(c) until a rectilinear structure with the least number of vertices is found.

Abstract: Touch pad based authentication of users. In an embodiment, a user can touch (and move on) a touch pad in a specific pattern (e.g., up, down, etc.) to authenticate oneself. In an embodiment, a device translates the touch movement to the same set of characters as those a user can manually enter using a keyboard to authenticate oneself. As a result, the user can use the same password when accessing the same application from other systems which have only keyboards, but not touch pads.

Abstract translation: 基于触摸板的用户认证。 在一个实施例中，用户可以以特定模式（例如，上，下等）触摸（并移动）触摸板以认证自己。 在一个实施例中，设备将触摸移动转换成与用户可以使用键盘手动输入来认证自己的相同的一组字符。 因此，当从仅具有键盘而不是触摸板的其他系统访问相同的应用程序时，用户可以使用相同的密码。

Abstract: A method and apparatus for automatically combining aerial images and oblique images to form a three-dimensional (3D) site model. The apparatus or method is supplied with aerial and oblique imagery. The imagery is processed to identify building boundaries and outlines as well as to produce a depth map. The building boundaries and the depth map may be combined to form a 3D plan view model or used separately as a 2D plan view model. The imagery and plan view model is further processed to determine roof models for the buildings in the scene. The result is a 3D site model having buildings represented rectangular boxes with accurately defined roof shapes.
