摘　　要：图转数(Picture to number)是将曲线图转化为数据与等式。用记录仪或手工绘出的曲线图,或者通过摄像技术从媒体上得到的曲线图,可用扫描仪录入计算机或者通过自身的数据线直接在计算机上传输与存储(数码相机,拍照手机等),通过计算机对这些曲线图像进行如下处理:载入图像资料(BMP)→抗噪声干扰处理→平滑与锐化处理→灰度化→二值化运算→细化运算→提取曲线骨架→捕捉曲线坐标,从而采集到需要对曲线进行数字分析的坐标值,提供给数转图的专门软件来还原曲线信息,实现曲线图形的精确复原和优化。Picture to number turns curve graph into data and equality.As the curve graph that the recording instrument is drawn,can input the computer with the scanner.Dealing with it as follows through the computer：Read and enter picture materials level and smooth to deal with → smoothing →two value operation → thinning →draw curve skeleton coordinate,in order to get the coordination value needed to analyze the curve by the figures,providing the specialized software to restore curve information and realize the accurate restore and optimization of the curve skeletons.
