摘要
本文根据国内外有关图象测量方面的文献资料及作者个人的科研实践,就如何从图象信号中提取特征信号的各种方法及适用范围做了综述。间接二值化法是本文作者提出的新概念,它适用于炉内加热工件尺寸和浮法锡槽内玻璃带宽度及边界位置的在线测量。对各种方法的优缺点及其应用范围进行了评价。
The author summerizes various kinds of feature signal extraction fromimage signals and their applicable ranges according to the literatures of imagemeasurement at home and abroad and his practice. The indirect binary modeis a new concept proposed by the author. It is applicable to on-line measur-ement of heating workpiece size in furnace,glass bandwidth in flcating tin trough and boundary positions. The advantages and disadvantages of variousmethods and their applying ranges are evaluated.
