IMAQ Rake for Polygon ROI?

[严严]

大家好！ 我在使用IMAQ vision中的IMAQ RAKE.VI是发现ROI只能是矩形区域，然而Vision Development Module 7.0.1 - Windows 2000/95/98/NT/XP - UPDATE中提到This is the IMAQ Vision 7.0.1 Update. It provides several enhancements to IMAQ Vision 7.0. It is a free download and IMAQ Vision 7.0 must be installed in order to run this update. The following feature have been improved: 1. Removed memory leaks associated with saving and loading images with overlays. 2. IMAQ Copy Overlay with the source and destination images the same now works correctly. 3. IMAQ Rake now works correctly with all Polygon ROIs. 4. The LabVIEW Image Display control displays more efficiently. 5. IMAQ Fit Circle 2 now returns the correct area and perimeter measurements.，可是我现在是8.0的版本，为何还是只能是矩形，若想用Polygon ROI，又该如何进行，谢谢

I am not getting the question.Can you explain it a bit more clearly?

The ROI for IMAQ Rake  must be rectangle or rotate rectangle. But I have to use the Polygon ROI for the input parameter.  So I want to know how resolve this problem. Thanks

Rake will not work with anything other than a rectangle.  Is your polygon always a rectangle?  If so, just convert it to a rectangle ROI.  If not, it just won't work.

Perhaps you could use the enclosing rectangle of the polygon ROI and convert it to a rectangle ROI.  This ROI would enclose your entire polygon area.  Depending on your application, it may do what you need.

如题和上图所示，在Vision Assistant完成测量步骤后生成VI提示错误找不到子VI，其中LabVIEW和Vision及Vision Assistant都是8.6版，搜索Rake时能找到IMAQ Rake 2.vi，但替换后错误很多。不知道各位有没有碰到类似问题，了解的请指教，多谢

When I generate VI from Vision Assistant, the error list reminds me subVI IMAQ Rake.vi of IVA Gauge Algorithm Min.vi does not exit，both the LabVIEW and Vision are version of 8.6.

Could you help me with this problem and give me some suggestion?

Thanks for your attention!
