- 論文の詳細を見る
New algorithm for perimeter measurement of a binary image has been developed. Two adjacent horizontal lines on the image are scanned simultaneously in this algorithm. Therefore, it is named the Dual Lines Scanning (DLS) method. Its perfonmance is so fast that it is suitable for real time measurement. Its configuration is so simple, hardware design is easy, also. It is proved that the accuracy of measurement by this method increases by employing rectangular pixel with large (optimum) vertical-to-horizontal ratio through experimental analysis. This fact is contradictory to the intuitive common sense, and the consideration is made on that cause. The simulation is also made on the characteristics of measurement for a simple figure image. It is concluded that this algorithm is very us useful for industrial application, especailly for measuring moving obJects because of the high-speed and simple configuration.
