改进后的方法能尽可能多地从图像中提取直线信息，既可以较准确地提取直线的端点信息，又能得到直线的准确表示。
Lastly least square method is used to fit for the straight line. The improved method can extract so much information as possible from original images.
然后使用lineToAPI来从这个起始点到传递到这个lineTo调用中的端点之间绘制一条直线。
Then use the lineTo API to draw a line from the start point to the end point passed in to the lineTo call.
给出了用两端点法、最小二乘法对平面内的直线度进行综合评定的方法。
