A three-dimensional map is displayed on a screen, and text data with different levels of density are displayed according to distances from a view point of the displayed three-dimensional map to nodes where the text data will be displayed, thereby improving readability of the text data. Further, it is possible to display the text data by locally adjusting the density of the text data on the screen. The three-dimensional map is displayed on the screen of a display panel by converting map data with two-dimensional coordinates into those with three-dimensional coordinates by means of a perspective projection method. Text data to be displayed together with the three-dimensional map are converted into those in a three-dimensional coordinate system with an origin defined by the view point of the three-dimensional map. The converted text data are projected on a two-dimensional plane to be converted into those with screen coordinates. Then, distances from the view point of the displayed three-dimensional map to the nodes where the text data will be displayed are classified. The classified distances are determined for the converted text data with the screen coordinates. Text data of levels corresponding to the determined distances are displayed on the screen of the display panel on which the three-dimensional map is displayed.

A method that estimates the coordinates of the calibration points in the projector image plane using local homographies obtained from the imaging camera. First, a dense set of correspondences between projector and camera pixels is found by projecting onto the calibration object an identical pattern sequence as the one later projected when scanning the target, reusing most of the software components written for the scanning application. Second, the set of correspondences is used to compute a group of local homographies that allow projection back of any of the points in the calibration object onto the projector image plane with sub-pixel precision. In the end, the data projector is then calibrated as a normal camera.

In a traffic information system, the principal component analysis of the floating car data collected in the past is performed for each traffic area. From among the bases representing the traffic data collected on the road-links in the traffic area, the bases which have strong correlation to the road-links on which real-time traffic data were collected are selected. The weighting coefficients for the selected bases are calculated by projecting the real-time traffic data onto the selected bases. The traffic estimation data are calculated by linearly combining the selected bases with the obtained weighting coefficients as the coefficients of the respective bases. The calculated traffic estimation data are used for the interpolation of the road-links on which the real-time traffic data were not collected.
