| 摘 要： | 针对当前对工程图尤其是图纸质量较差的旧图纸的全自动矢量化还没有完全成熟可靠的算法，提出了一种新颖快速的半自动矢量化方法，即通过少量的人机交互，在点阵上进行跟踪，得到工程图纸上的矢量，同时也可将矢量所对应的光栅提取出来．既可对工程图纸进行矢量化，又可对其进行智能编辑．算法的特点是快速，准确，并具有良好的鲁棒性，对较差的蓝图也能取得理想的结果

| Abstract: | A novel and fast algorithm for semi vectorization of old engineering drawings is developed. With a few user interactions, the vectors on the drawings can be obtained by tracking on the point array. It can also be used to extract the point array corresponding to the vectors in order to carry out the intelligent editing of engineering drawings. The algorithm proposed is characterized by fastness, accuracy, and good robustness and can be used to deal with a drawing of rough quality such as blueprints as well. |
