A map generation device is configured to determine evaluation value of each of a plurality of evaluation items that serve as indices for evaluation the reliability of the positional information of the planimetric feature. The plurality of evaluation items include any of an error amount when arrangement of composing points of the planimetric feature is approximated, a parallelism between an arrangement direction of composing points of the planimetric feature and a movement trajectory of the measuring vehicle, a distance between a position indicated by the position information of the planimetric feature and a position of the measuring vehicle when the position of the planimetric feature is measured, an absolute value of reflection intensity of a position of the planimetric feature obtained from the measurement information or a difference between a position of the planimetric feature and surrounding reflection intensity of the planimetric feature, and so on.

Map generation device and map generation system

Map data is managed by being divided into a geometric information data list of pieces of geometric information or a phase information data list of pieces of phase information, an attribute information data list of pieces of attribute information, and a relation information data list of pieces of relation information each indicating a relation between the geometric information or the phase information and the attribute information. The pieces of attribute information in the attribute information data list are arranged in the order corresponding to the pieces of geometric information or phase information which are feature information, and the pieces of relation information are arranged in the order corresponding to the pieces of geometric information or phase information which are feature information.

Navigation device and navigation method

Disclosed is a 3Dimension stereoscopic display device including a video image playback devicefor playing back a right-eye image or video image and a left-eye image or video image for three-dimensional stereoscopic display which are based on an inputted image or video image, a stereoscopic display monitorfor producing a three-dimensional stereoscopic display of the right-eye image or video image and the left-eye image or video image and a screen composition processing unitfor generating the right-eye image or video image and the left-eye image or video image in which a virtual display surface for three-dimensional stereoscopic display of the image or video image differs from the screen of the stereoscopic display monitor, and for outputting the right-eye image or video image and the left-eye image or video image to the video image playback device

3Dimension stereoscopic display device

Disclosed is a 3Dimension stereoscopic display device including a screen composition processing unit for generating a right-eye image or video image and a left-eye image or video image for planar display or for three-dimensional stereoscopic display of an image or video image, a video image playback devicefor playing back the images or video images, and a stereoscopic display monitor unitfor displaying the images or video images played back by the playback devicein a three-dimensional stereoscopic manner, in which the screen composition processing unitswitches between outputting the right-eye image or video image and the left-eye image or video image for planar display to the playback deviceand outputting the right-eye image or video image and the left-eye image or video image for three-dimensional stereoscopic display to the playback deviceaccording to state of a moving object.
