摘　　要：针对传统的交互式矢量化方法中的某些问题,如:损失了原图的色彩和线宽信息、目标的属性信息还原困难等,提出了在彩色原图上进行交互式矢量化的方法。这种方法可更好地利用了原图上的线宽和色彩信息还原工程图的属性信息.首先,在彩色底图上选取种子点,运用彩色图像分割方法选取出种子点所在的整个地物;然后,分析目标的线宽、色彩等信息,还原出目标的属性信息;最后,把组成地物的所有点认为是同样颜色的点,运用传统的二值图像矢量化方法得到矢量空间数据。A new interview vectorizaton method based on color engineering geologic drawing is presented that can overcome some issues in traditional interview vectorization,e.g.,loss of info on the color and the line width in original drawings,difficulty in retrieving attribution data.The proposed procedure can utilize the info on the line width and color in original drawings to identify the attribution data.Firstly,a seed is selected on the color engineering drawing,and the whole object is selected using image segment method.Secondly,the attribute information of object is retrieved through analyzing the line width and color info.At last,the traditional vectorization method can be used to get spatial vector data regarding all the pixels of the object as the same color pixels.
