Re-vectorization is performed on the basis of original vectorization by obtaining the initial parameters such as line types and slope. Inuring tricing it can adjustthe parameter adaptively. To decrease the influence of noise pixels, we designed a stop probe to detect tracing-stop conditions. Process of re-vectorization is performed recursively until quality of graph entity is satisfactory.Finally, some key technologies for 2D graphs reconstruction are studied. The issues concerned include the recognition and presentation of topologic relations among graphs entities and a directed and weighted graph model established to describe the relations and techniques on dimension driven.

在获得对图素识别质量的评价之后，质量较差的图素被输入到错误自动校正器进行错误校正处理，本文提出&二次矢量化&的错误校正思想，二次矢量化是在初步矢量化所获得知识的基础之上，取得初始参数，并在跟踪过程中动态校正参数，在跟踪结束时引入跟踪终止检测探针以消除光栅图像中黑白噪音的影响，使得算法具有较强的抗噪音干扰能力，校正后的图素仍需进行质量评价，未能通过评价的图素需递归执行二次矢量化算法。
