How can I find the vanishing point with Labview?

I am using a myRIO for developing a system for helping visually imapaired people in their navigation. I have already done the image processing of what is being aquired by the camera (edge detection and finding of straight lines).
How can I fin the vanishing point from the two edges of a path in an image with LabVIEW? Is there any special function that I can use?
Thank you!
Solved!
Go to Solution.

The vanishing point is the intersect of two lines, right?

    Thanks in advance.

    Hi Kumar,
    You can goto WE02 T'code and give the IDOC number (check date range).  Click on Status Records.  It shows the exact error. 
    If IDOC fails it is gives your the status 51 otherwise it gives you the status 53.

  • How can i control the I2C bus with Labview

    Hi
    How can i control the k8000 from http://www.velleman.be ( I2C bus) with
    Labview.
    all info is welcome.

    if you are using Linux (and the Linux version of LabVIE W) it should be
    fairly easy to use the lm_sensors ( http://www.netroedge.com/~lm78/ )
    libraries and source code to control a device connected to a PC's I2C bus.
    Go here http://www.netroedge.com/~lm78/hardhack.html to see how to tap into
    the I2C bus of your PC. You may be able to apply info here to roll-your-own
    on a MS Windows 98 / 2000 OS.

  • How can i control the Tektronix AFG3022 with LabView 7.0

    I am trying to control the Tektronix AFG3022 Function Generator with LabView 7.0. Is there a premade program I can download and use?

    If it is not in 7.0 make new thread and ask nice if someone can convert to labview 7.0.
    Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
    (Sorry no Labview "brag list" so far)

  • How can I find the position of a robotic arm with a cFP-CTR card?

    Hello,
    I use a CTR-500 to measure the pulses of 3 encoders.
    The encoders are related to the 3 axis (x,y,z), to which a robotic arm is moving.
    Each encoder has 2 channels (A,B) which go to each pair of Count Inputs of the CTR card.
    When the robotic arm is moving on one axis, the corresponding pair of Count Inputs is increasing, but there is a phase between the one Count Input and the second one. What is more, the Count Inputs do not decrease when the robotic arm is moving to the other direction, but they still increase.
    So, I cannot find easily the position of the robotic arm.
    What I have done, is to try finding the position, by using only one Counter Input for each axis. This means that I use the value of the encoder as a counter, and I calculate the position with some software tricks. But for some reason, it does not work properly.
    I have heard that the method I use is not proper. Instead, I have been told that I must use the phase of the 2 Count Inputs, in order to find the direction to which the robotic arm is moving. But, the Count Inputs of the CTR are augmenting in parallel, when the robotic arm is moving forward or backward.
    How can I find the position of the robotic arm, as it is moving like a CNC ?
    Thank you very much.

    You don't want to use a cFP-CTR-500 card.  What you have are quadrature signals.  You should be using the cFP-QUAD-510.  It has 4 channels that can handle both the A and B signals of a quadrature encoder.  It has the built in circuitry do determine the phasing of A vs. B to know when to count up vs. count down.

    how can I find the Image number of a particular photo in the Photos app included with iPad Air?

    Hello yamacutta,
    Thanks for using Apple Support Communities.
    The Photos app will not show you the actual file name of the photo.  However when you go through the image import process on your computer, you should be able to see both the thumbnail of the photo, as well as the filename of the image.
    Import photos and videos from your iPhone, iPad, or iPod touch to your Mac or Windows PC - Apple Support
    Take care,

    Try going to the following

    You can also access this by way of keyboard shortcut Ctrl + U
    The View Page Source option is also available via the right-click menu by just right-clicking inside the page window & it will be the penultimate menu item.

    Hi Siva,
    Small correction here as said by our friend Tao.
    vbrp has no relation with bkpf.use vbrk.
    vbrk-bukrs = bkpf-burks,
    vbrk-belnr = bkpf-belnr,
    vbrk-gjahr = bkpf-gjahr.

  • How can we find the hostname of the devices connected with the interfaces of switch?

    how can we find the hostname of the devices connected with the interfaces of switch ? I have tried mac address and ARP, there are lot of servers connected with the switch having multiples LAN cards. So mac table shows the mac of physical machine as well as virtual machines. But i want to know only the physical machines. Is there any other method to find out the IP address, hostname of the physical machines only? 

    Hello Leo Laohoo
    Thanks for this information
    In our network most of the Servers are not of Cisco. Some of them are Vmware machines, some are Hyper V machines, etc. 
    Does IP device tracking show us only the IP addresses of the Physical Machines of the Vmware Server not of Virtual Machines?

    Your description indicates that you bought an upgrade version... which requires proof of a previous version to install

  • How can I find the location of an app on my iPad 2?

    How can I find the location of an app on my iPad 2? The app comes up with a search, but that seems to be the only way to find it. I just installed the app today, but I can't figure out where it is. It has a pretty distinctive icon, and I've looked through all of my apps and even in folders (even though I don't know how it would have gotten there). I want to put it in an appropriate folder under the right subject, but I can't find it to do this. I can use the app, since I can find it through a search though. I have a lot of apps, but I looked very carefully and can't find it. Is there a way to ask my iPad to locate it for me? It's a $25 app and one I plan to use regularly, so I want it located in the folder of my choice.This problem makes we wonder if I have other "missing" apps, apps that I could  find if I happened to think to search for them, but that don't appear to be on my iPad (even though they actually  are).

    You were right about the homescreens. I had turned my iPad off for the night with less than three full homescreens of loose apps, those not in folders. When I turned the iPad on this morning to try your suggestions, I had five full pages of loose apps. They just appeared when I restarted, and there was the app I was looking for, easy to find. Last night I was deleting apps I decided I wouldn't use, organizing useful apps into folders, and making sure I had as few pages as needed by making sure the gaps made by the moved/deleted apps were closed. The missing apps didn't show up at that point; I was just left with fewer than 11 pages. The apps only showed up when I restarted this morning. There were almost three extra pages of apps that weren't there last night. I know there must be other things missing, since all of the pages are full. So I tried your suggestion in iTunes. I connected my iPad, found an app in the alphabetical list on the left, and double clicked it. This brought me to the app's homescreen (and its home folder when applicable), the place where it was located. In order to identify which page that was, I had to scroll through the screen shots of the homescreens that was below the homescreen that was showing until I found the homescreen whose number was in white. Then I could count the pages on my iPad until I got to that page. I'll have to delete more apps and organize more into folders to see what else might show up. There are just too many apps available for special education, and I'm in the process of figuring out which are the best for my needs. Thanks so much!
