摘　　要：介绍了焊缝缺陷工业X射线电视探伤的计算机图象处理技术。为了提高图象的对比度和清晰度,以及减小噪声,成功地采用了图象重建和增强的方法。工业X射线电视探伤的图象处理是一种新的X射线检查焊缝的方法,具有高灵敏度、快速实时检验的特点,将被广泛地应用于工业中。An introduction of digital image processing for X-ray real-time inspection of weld defects is presented in the paper. The image restoration, enhancement and binarization technique have been successfully used to reduce noises, to increase image contrast and definition effectively. Digital image processing for X-ray real-time inspection of weld defects is a new method for weld quality control which has high sensitivity and eificiency. It will be widely used in industry in the near future.
