摘要
指出了射线实时成象中图象拼接的重要性,分析了对图象匹配的算法和减小计算量的措施,对图象拼接的方法进行了研究,提出了在被测对象发生旋转的情况下进行拼接的“特征线”法,为大型被测对象的整体检测创造了条件。
The importance of image splicing for real-time imaging radiographic inspection is pointed out. The image-matching algorithm and the methods to reduce calculation are analyzed while the methods for image splicingare investigated. 'Symbol line' method is proposed for image splicing in case that the object under inspection is rotated, which makes it possible for global inspection of large objects.
