Title:
INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2015/071940
Kind Code:
A1
Abstract:
An information processing device according to the present invention comprises a GPS sensor, a direction sensor, a display unit, a manipulation reception unit, and a control unit. The information processing device further comprises a storage unit for storing three-dimensional data for a building and the coordinates of a predetermined location where the building is planned to be built, and a camera for capturing an image of the site where the building is planned to be built, wherein: the GPS sensor detects the coordinates of the present position of the information processing device; the direction sensor detects the direction in which the camera faces; the manipulation reception unit is capable of receiving manipulation by the user holding the information processing device; and on the basis of the three-dimensional data for the building, the coordinates of the predetermined location of the building, the coordinates of the present position of the information processing device, and the direction of the camera, the control unit renders a perspective image of the building as viewed from the camera serving as a viewpoint, causes the display unit to display a composite image formed by superimposing the perspective image onto the captured image of the site, and if a first manipulation has been received from the user, the control unit stores the coordinates of the present position of the information processing device as the coordinates of the position of the information processing device at the time of the reception of the first manipulation, adjusts the captured image of the site in accordance with changes in the coordinates of the position of the information processing device and in the direction of the camera while maintaining the perspective image in the display state at the time of the reception of the first manipulation, and if a second manipulation has been received from the user after the first manipulation, then the control unit calculates the difference between the coordinates of the position of the information processing device at the time of the reception of the first manipulation and the coordinates of the present position of the information processing device, as detected at the time of the reception of the second manipulation, terminates the maintenance of the abovementioned display state, and uses the calculated difference as a correction value to be added to the coordinates of the present position of the information processing device when rendering the perspective image.
