INFORMATION SYSTEM, SERVER DEVICE, TERMINAL DEVICE, INFORMATION-PROCESSING METHOD, AND PROGRAM

摘要

To solve the problem that identifying imaged objects requires a large amount of time, a terminal device is disclosed that is provided with: a camera unit that stores at least one object information item and acquires imagery, said object information item comprising an object identifier and region information for an object; a terminal information acquisition unit that acquires terminal information comprising position information and direction information; an imaged object decision unit that applies the terminal information and a view angle to the region information in each object information item, examines each imaged object in ascending order of distance from the device, marks information for regions that become invisible due to object imaging as invisible regions, and stops examining when there are no more visible regions; an imaged object information acquisition unit that acquires at least one decided imaged object information item; and an output unit that outputs the imagery and at least one imaged object information item. This makes it possible to identify objects imaged by a camera and output information pertaining to said objects.
