jbelim Posted January 17, 2008 Report Share Posted January 17, 2008 Hi everyone, I have to do a school project that requires me to find the area and volume of a throat. I'm given the picture which I have attached here and I'm supposed to use Labview to find the area and volume of the dark circle (throat). The problem is, I'm totally new to Labview and have little prior experience with programming. I attempted to find out what Labview and Vision and Vision Builder means but I'm totally stuck right now. It's like being thrown into the deepest end of the pool not knowing how to swim. Would really appreciate if anyone can give me any help or point me to the right direction because I urgently need to produce my work and I'm feeling pretty frustrated. Thank you so much.

First, do you have a copy of LabVIEW, NI Vision, and NI Vision Builder? Take a look at the http://zone.ni.com/devzone/cda/tut/p/id/3470' target="_blank">Image Analysis and Processing document on the NI Dev Zone for a quick intro to image processing. Then ask yourself the following questions: What are the distinguishing features of what I'm looking for in the image? What's the easiest way to filter out anything that is not a distinguishing feature? How do I quantify the item of interest, once I've filtered out everything else? Hint: You don't really need NI Vision to solve this problem, since what you're looking for in the image has a very distinguishing characteristing. Quote Link to comment

AFAIK, Matlab is a good choice for theory processing esp. image processing. Also IMO, LabView is more close to real application (GUI) and hardware interface. Quote Link to comment

LabVIEW is more than just GUI and hardware interface. The NI Vision is full fledge vision analysis toolkit and easy to implement. I hope it makes sense and jbelim feels motivated :thumbup: -- Ashish Quote Link to comment

Well, in my experience I am coming from asm, C, C++, Matlab then to LabView, though I use several of them at the same time. Anyway, jbelim goodluck for your project. I think Lavag members will kindly help you, as they helped me many times :thumbup: Quote Link to comment
jbelim Posted January 18, 2008 Author Report Share Posted January 18, 2008 Thanks for your help, guys. And thanks for your hint Jim Krings. I will look into the link you gave and hopefully be able to solve the problem. Thanks once again. Will ask you all again if I'm stuck! :DHi guys,I have several questions that I hope someone can give me advice on.1.Jim Krings, you said that I don't really need to use NI Vision. Does it mean that I can just use Labview to solve this problem? I'm thinking to change the image to grayscale and then use Labview to count the darkest pixels for the area. How can I use Labview to do that?2.I have a video of the scope going into the throat. Can labview acquire three images while the video is running, calculate the area and the volume between the first and 3rd image?Many thanks for your time! Quote Link to comment
