초음파를 이용한 형상인식에 관한 연구 = A Study on Shape Recognition Using Ultrasonic

다국어 초록 (Multilingual Abstract)

Recently a number of researches have been performed for the various methods of shape recognition of objects. An algorithm was developed for the recognition fo shape of arbitrary objects using ultrasonics. It was possible to measure the distance, the thickness and the real shape of the objects as well as the image of them using the experimental method developed here. Thus, the following results were obtained: (1) the basic algorithm for the recognition of shape of arbitrary objects can be applied to the real structures in the industry, (2) the error of measurement using the current method in within 1-6% compared to the real shape, and (3) in order to obtain the more accurate results, the minor errors in the algorithm and for the incident waves are being studied.
