摘　　要：应用Visual Basic 6.0图像识别技术开发了简易计算机读图软件。将待读关联图扫描进计算机并载人软件中,用VB 语言PictureBox 控件中的颜色识别功能来判定曲线上的点,用鼠标事件来返回点的控件坐标值,通过坐标变换得到点的实际坐标值,从而实现利用计算机读图的功能。读图示例表明,计算机读图比人工读图方便、快速、准确。读图软件可应用于需经常查图计算的化工等领域。The software of computer reading graph was developed by using image recognition techniques of Visual Basic 6.0.The cor-relation graph was scanned into computer,and then was loaded into the software.The point of the curve of the correlation graph wasrecognized by color-recognizing function of PictureBox of VB.The controlbox coordinate of point was returned by mouse event,and thetrue coordinate value was obtained by coordinate transformation,as a result,the method of computer reading graph was realized.Theexample of reading graph indicated that computer reading graph was more convenient,faster and more accurate than manual readinggraph.The software can be applied in many fields such as chemical engineering in which calculation by artificial searching graph wasneeded constantly.
