摘要： The invention relates to a map display apparatus comprising memory means (3) for storing map data necessary for plotting a map of a predetermined region; map display means (65) for displaying a bird's eye view map by using the map data read out from said memory means; display region limiting means (81) for limiting regions for bird's-eye view display to those regions existing on the foreground side from a disappearing point of perspective conversion; background display means (86) for displaying an artificial background such as a horizontal line and sky in the regions for which map display is limited by said display region limiting means; and background region control means (86) for changing colors and patterns of the artificial background regions displayed by said background display means.

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.

摘要： Whether the structure data read from the map data correspond to a non-decomposition structure or a decomposition structure, the drawing attribute of the mesh boundary is modified for the decomposition structure, and textures such as windows are mapped on the side wall of the structure by mapping the texture on the side wall of the structure reconstructed after reconstructing the single-bodied structure before decomposition, or mapping the texture progressively on the side wall of the decomposition structure with the stored start point and end point of the texture to be mapped.
