本研究運用光學字符辨識技術來實作無標記式擴增實境，並將其運用在光學式英文電子字典。

使用擴增實境技術，用立體的影像取代原本光學式英文電子字典翻譯的文字，投影在想要翻譯的英文單字上。使用立體的影像不但可以直覺且準確的表達想要翻譯的單字，更可以避免同字異意所造成的誤解。

使用光學字符辨識技術取代標記(例如:QRcode)，可以增進原本使用標記式擴增實境技術的產品(例如:故事書、導覽等)的閱讀性和美觀，使用者也無須針對每一種不同的標記使用特定的應用程式。



關鍵字：無標記式、擴增實境、光學字符辨識

In this study, we use optical character recognition technology to implement markless augmented reality system, and use in electronic English dictionary：

Using augmented reality technology, we can replace the text translated by original electronic English dictionary with three-dimensional image. The three-dimensional images can not only have more intuitive and exactly expression of the word, but also avoid misunderstandings caused from different meanings with the same word.

By using optical character recognition to replace the tag (for example: QRcode), better appearance and this system can provide readability of those augmented reality products (such as: story books, navigation, etc.). Beside, user doesn’t need to download different applications for different tags.



Keywords：markless、augmented reality、optical character recognition
