Patent number: 8614703Abstract: A map editing system for processing map data in order to reduce discrepancies between geometric objects in the map data through the use of a cost function. The system selects a polygon shaped object (e.g., a park) for processing.

Publication number: 20120116675Abstract: An illustrative embodiment of a computer-implemented method for projecting geographic coordinates into a coordinate space of a target image enabling navigation of the target image is presented which performs an initialization using a set of geographic reference points, receives a set of points in the coordinate space of the target image, receives a one-to-one mapping between the set of geographic reference points and the set of points in the coordinate space of the target image, computes a triangulation of the geographic reference points of each respective set of geographic reference points, identifies a containing triangle represented in the triangulation in which an arbitrary geographic coordinate point is located, identifies points in a space of the target image corresponding to vertices of the containing triangle, interpolates a location within the containing triangle to form a resulting location and superimposes the resulting location onto the target image.Type: ApplicationFiled: February 8, 2011Publication date: May 10, 2012Applicant: International Business Machines CorporationInventor: Michael A.

Patent number: 8150619Abstract: An automobile navigation system determines whether or not the relevant vehicle is traveling and whether or not routing assistance is being provided. When the results of both the determinations are affirmative, a displayed map image is scrolled by an amount of scrolling corresponding to the size of a guided route in response to an operation to a touch panel for scrolling, and, further, the scale of the display map image is changed by an amount of change corresponding to the size of the guided route in response to an operation to the touch panel for scale change.Type: GrantFiled: July 17, 2007Date of Patent: April 3, 2012Assignee: DENSO CORPORATIONInventor: Hirokazu Sakano

Patent number: 8145423Abstract: A navigation device and a route guiding method. The route guiding method includes: displaying a current map including a position indicator; displaying a related map that corresponds to the current map; and displaying the current map after a set period of time has elapsed. The set time period can be set by a user. Therefore, the travel simulation of the route from the current position to the a location desired by a user may be displayed, or the route may be zoomed in or out to be displayed, based on settings input by a user, and thus the user can travel safely.Type: GrantFiled: November 2, 2007Date of Patent: March 27, 2012Assignee: Samsung Electronics Co., Ltd.Inventor: Seung-hoon Ohn

Patent number: 6404328Abstract: An object sensing system is capable of distinguishing an overhead roadway object, that is not in a host vehicle path, from a substantially motionless roadway object that is in the vehicle path. Initially, a plurality of sensor scan signals are provided into an anticipated path of a host vehicle. Next, a plurality of object return signals that correspond to reflections of the plurality of sensor scan signals from at least one detected stationary object are received. Then, an average amplitude slope of the return signals as a function of the range to the at least one detected stationary object is determined. A sufficiently positive amplitude slope identifies the detected stationary object as an overhead roadway object that is not in the vehicle path. A sufficiently negative amplitude slope identifies the detected stationary object as a substantially motionless roadway object that is in the vehicle path.Type: GrantFiled: October 24, 2000Date of Patent: June 11, 2002Assignee: Delphi Technologies, Inc.Inventors: Stephen William Alland, James Fredrick Searcy
