重点工具使用流程

CogFindLineTool工具

步骤一：使用找线工具将传感器左边特征给寻找出来；

 步骤二：使用找线工具将传感器右边特征给寻找出来；

 步骤三：使用找线工具将传感器上边特征给寻找出来；

 步骤四：使用找线工具将传感器下边特征给寻找出来；

CogIntersectLineLineTool工具

步骤一：将左边直线和上直线进行交叉处理；

 步骤二：将右边直线和上直线进行交叉处理；

 步骤三：将左边直线和下直线进行交叉处理；

步骤四：将右边直线和下直线进行交叉处理； 

CogCreateSegmentTool工具

步骤一：将右边直线和上直线进行交叉与左边直线和下直线进行交叉，实现右倾斜进行测量···

 步骤二：将右边直线和上直线进行交叉和右边直线和下直线进行交叉，实现右倾斜进行测量···

CogIntersectSegmentSegmentTool工具

将CogCreateSegmentTool工具1和CogCreateSegmentTool工具2计算两条线段（Segment）的交点坐标，然后计算出传感器所需要的宽高。
