Description

制御ユニット１３は、演算制御装置１３ａと、文字認識用データベース１３ｂ、称呼データベース１３ｃと、バッテリー１３ｄとを有している。バッテリー１３ｄは、視覚認識支援装置１に電力を供給する電源である。 The control unit 13 includes an arithmetic control device 13a, a character recognition database 13b, a naming database 13c, and a battery 13d. The battery 13 d is a power source that supplies power to the visual recognition assisting apparatus 1.

＜称呼情報取得処理＞
次に、演算制御装置１３ａは、文字認識が行われた後の文字列を単語等の要素に分解し、その後、分解された単語等に対し、称呼データベース１３ｃに登録されている称呼をあてはめることで、文字列の称呼を取得する。称呼データベース１３ｃは、文字および単語（つまり、検出処理で検出されるオブジェクト）に対し、その称呼（読み方）が対応付けられた辞書である。称呼データベース１３ｃは、図１に示すように、視覚認識支援装置１のメモリに記憶されていてもよいし、通信ネットワークを介してアクセス可能なサーバ上のメモリに記憶されていてもよい。この場合、視覚認識支援装置１は、外部との通信装置（図示せず）を備える。 <Name information acquisition process>
Next, the arithmetic control unit 13a decomposes the string after the character recognition is performed to the elements of a word or the like, with respect to the decomposed words like, addressed the nominal registered in the nominal database 13c is By retrieving, the title of the character string is acquired. The name database 13c is a dictionary in which names and readings are associated with characters and words (that is, objects detected by the detection process). As shown in FIG. 1, the naming database 13c may be stored in the memory of the visual recognition support apparatus 1, or may be stored in a memory on a server accessible via a communication network. In this case, the visual recognition assisting apparatus 1 includes an external communication device (not shown).
