标题: 1.8 halcon 上位机使用测量助手测量内六角扳手间距宽度
在上一帖子里是通过代码实现，内六角扳手间隔的测量，

其实还可以直接使用测量助手实现，更多直观，更方便
同样，打开测量助手 窗口，

从磁盘转入图像C:/Users/Public/Documents/MVTec/HALCON-17.12-Progress/examples/images/bin_switch/bin_switch_8.png
使用窗口工具栏 上的绘制直线，来确定在图上要测量的内六角扳手，
在边缘选项卡中来回调节参数，如最小边缘幅度，平滑等，边观察图片上边缘提取效果。
在结果选项卡中可以看到生成的计算结果。
在生成代码选项卡内，点击插入代码，可快速生成代码用于导出使用。
