摘要： In a navigation system using a bird's-eye view display mode, map data on a plan view map are subjected to a perspective projection conversion to obtain drawing data on a bird's-eye view map. In this case, an input of the position of a view point is accepted, and a projection plane for a bird's-eye view is determined on the basis of the coordinates of a current position and a destination and the position of the view point so that the display positions of the two points which have been subjected to perspective-projection conversion are coincident with predetermined positions. Alternatively, an input of a scale is accepted, and the position of the view point and the projection plane are determined on the basis of the coordinates of the two points and the scale so that the display positions of the two points after the perspective projection conversion are coincident with predetermined positions and the drawing scale is coincident with the input scale. Or, as a further alternative, an input of the projection angle is accepted, and the projection plane is determined on the basis of the projection angle and the position of the view point.

摘要： A travel environment information collecting device mounted on a vehicle comprises a collecting means (12) which collects travel environment information of a road on which the vehicle concerned is travelling, a receiver means (14) which receives travel environment information being transmitted from an information center which stores an advance travel environment information, a judgement means which judges whether a processing of updating or new generation for a part of the received travel environment information is necessary by making use the collected travel environment information; and a transmitting means (13) which transmits the travel environment information collected by the collecting means and to be used for the concerned processing to the information center when the judgement means judges that either the updating processing or the new generation processing is necessary.

摘要： The view point-setting part (305) calculates the position of the view point V to be set behind the current position of the car and up in the air, based on the current position calculated by the current position-measuring part and the position correcting part (307). The data reading part (308) reads out map data M (3) about map elements such as buildings, which are located around the current position. The representing method-changing part (312) calculates the distance or level difference between the view point and each of the map elements, and, for example, changes the representation shapes of ones of the map elements near the view point, that is, in the region within a predetermined distance from the view point, to detailed shapes, and the rest ones far from the view point, that is, outside the region within a predetermined distance from the view point, to simple shapes, respectively. Finally, the display processing part (311) composes an image of each of the map element according to the displaying mode of the map element, which is sent from the representation method-changing part (312), and displays the image.
