Information display system, information display apparatus, information provision apparatus and non-transitory storage medium

摘要

The utility of a service using AR is improved. The information display apparatus which applies an information display according to augmented reality (AR) acquires a reference image for matching with a subject in a captured image and scale information which shows a scale of the subject in the reference image from an information provision apparatus. Then, an inputter-outputter of the information display apparatus displays the captured image as well as a distribution of the reference images by a scale of the subject. On this distribution display, a guide display according to the scale of the subject in the captured image is performed. This guide display moves on the distribution display corresponding to a change of an angle of view. Accordingly, it is easily set the angle of view by which the matching using the acquired reference image can be performed appropriately, and the convenience improves.

主权项

1. An information display system for displaying information comprising:
an information display apparatus which includes an imaging unit; and an information provision apparatus; wherein the information display apparatus comprises:
a key information acquiring unit which acquires key information corresponding to a subject in a captured image captured by the imaging unit; anda key information transmitting unit which transmits the key information to the information provision apparatus, wherein the information provision apparatus comprises:
a reference image storage unit which stores (i) a plurality of reference images including reference subjects and (ii) actual-size-related scale information of the reference subjects and superimposing information corresponding to the plurality of reference images, respectively; andan information providing unit which selects at least one of the plurality of reference images based on the key information, and which provides to the information display apparatus (i) the at least one selected reference image and (ii) the actual-size-related scale information and the superimposing information corresponding to the at least one selected reference image; and wherein the information display apparatus further comprises:
a guide displaying unit which displays actual-size-related guide information based on (i) the actual-size-related scale information corresponding to the at least one selected reference image, and (ii) actual-size-related scale information of the captured image;an image matching unit which matches the subject included in the captured image with the at least one selected reference image in accordance with the displayed actual-size-related guide information; anda superimposed displaying unit which superimposes and displays the superimposing information corresponding to the at least one selected reference image based on a matching result matched by the image matching unit on the captured image.
