How to use IMAQ detected Shapes.vi

Hi all

I learn NI Vision, I don't understand how to use IMAQ detected Shapes.vi to detect shapes, such as lines, ellipses, who can give me an example, thank you.

Hello

This function uses the edges of the object and try to adapt with different shapes such as rectangles, lines, or some cirles.

First of all, you need to set parameters to extract the edges of your objects. You Brown the threshold (in order to find the correct edges of your object). You can then choose the parameters of the shape to fit. For example if you want to adjust with a circle, you set the min and max possible RADIUS.

Try this with vision assistant, it will be easier. And try also with fine contrasting images.

  • What is the difference this 2 examples of photos? Use function IMAQ detect circles to detect the GREEN button.

    Hi all

    Please refer to the attached 2 pictures, they are similar, just the size is defferent. (pass PNG, 5478 pass. PNG).

    But now I try to use IMAQ detect circles to catch the GREEN button. For the PNG pass, it works very well, but for another example, it is still does not detect this button.

    I also try to change the curve settings and note that entry, but still no. Another way, I also try to use function IMAQ find circles , but the result is worse that IMAQ detect circles, so give up.

    The code is detect the circles.png, copy of block diagram.

    So what is the root cause? Thanks for help.

    Hi colinzhang,

    The extraction of curve so it uniform mode, you can get the result.

    -Suggestion, if you want to use the entire image area as KING should get the size of the image, get the rectangle and convert it to the descriptor of KING. (I think this is unnecessary)

    -Be careful with the extraction of the plane, u use default color which is the Red plan. In this example, it is fine. but make sure you know what aircraft you are extracting.

    s ' Please find vi saved in the 2010 version.

  • How do I auto detects the target using the trigger VBAI mode

    Hello world

    I had a vision system of machine ready to take choose using VBAI 2013 sp1.  Also, I use a sensor switch to trigger the camera to take pictures.

    When I type the loop running, it just won't continue to take photos no matther switch sensor triggers the camera or not.  I think it's the step that I used for the recording of the image, in the stage of registration of the image, I used picture newspaper still, but I don't want to use which is only what inspection status allows no other choice.

    So, how can I let the unit wait until he got the trigger of the alarm switch signal, and then take a picture and save the image?

    the stage of inspection to acquire the image, I used the trigger mode and everything worked fine, except the time error settting upward, I used 5000ms and if I put bigger like the 50000ms, VBAI turned really slow and showed time out error.

    If anyone can help me on this matter?

    Thank you

    You can use the diagram States-transitions to go only in a State based on the result produced by some steps.

    First, remove the registration step of the image of the State to check with you get the image

    Press Ctrl + E to turn the main view on the state diagram.

    Right click and create a new State.

    Right click on the State to inspect and create a new transition to this new State.

    Double click on the transition to edit it.

    Choose to acquire the Image - waiting time and set the condition false, to spend in this state when there is no timeout.

    Move the default transition from that State to the final State.

    Click on the new State to select it, and then add the image registration step.

    Using a state diagram, you have programmed an inspection that will record the image when there is no timeout.

    The State-transition diagram is a powerful tool to add a logic, branching and looping of your inspection.

    Open the tutorial 5 - state diagram Branching.vbai and tutorial 6 - State chart Looping.vbai for examples on how to use it.

    I hope this helps.

    It would be useful if you have linked the articles you found before you write. If I know you already read about it, I would have not spent time looking for you.

    The items I linked to are quite detailed. I doubt that this would trigger the SPAM detection, though - that's just my opinion of many years dealing with SPAM.

    Regarding your last question, well, only you know why you would need it in the first place. It took years for people (and the email clients) even consider using HTML, fonts are another component of this discussion (ie. content vs presentation/container). Personally, I don't receive e-mails with too much formatting.

  • How to use the utility to update (uefi) BIOS HP

    Notebook: G62 a10em

    I downloaded the BIOS update tool from http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=4063 & lc = on & cc = us & dlc = in & sw_lang = & product = 4226...

    and it is installed on my USB key.

    Now, how can I update my bios?

    The USB key contains now:

    BIOS

    | - Current (empty folder)

    | - New (empty folder)

    | - Previous (empty folder)

    BIOSUpdate

    -CryptRSA.efi

    -CryptRSA32.efi

    -HpBiosUpdate.efi

    -HpBiosUpdate.s09

    -HpBiosUpdate.sig

    -HpBiosUpdate32.efi

    -HpBiosUpdate32.s09

    -HpBiosUpdate32.sig

    my current version of bios is f. 08

    I did a cut above.

    After looking at the appropriate file you downloaded, it says this:

    "Prerequisites .
    -Microsoft .NET 2.0 is required. UEFI and Custom Imaging - the HP BIOS update must be run from a FAT or FAT32, partition with a volume of the "HP_TOOLS" name This Installer gives you the option to install on the hard disk (HDD) or USB. If you install on the HARD disk and the HP_TOOLS partition is not present, Setup prompts to create the HP_TOOLS partition. If you install on a USB key, Setup renames the partition on the USB in HP_TOOLS. If you use a custom image, you can create the HP_TOOLS partition manually with the type FAT32 and that the volume HP_TOOLS name. ATTENTION:-the UEFI system partition is not protected and can be removed. -Backup of the computer by using the complete PC Backup feature of Microsoft Windows Vista does not save the UEFI system partition. For these reasons, HP recommends that you place no additional data on the UEFI system partition. Because the partition is not backed up, corruption or failure of the partition will result in the loss of all data on the partition, as well as the loss of UEFI functionality. "For more information, visit: www.hp.com/go/techcenter/startup"

    There is little documentation on how to use it, but a Member here figured it out.

    http://h30434.www3.HP.com/T5/operating-systems-and-software/envy-14-system-recovery-doesn-t-work-with-latest-BIOS/m-p/328684/highlight/false#M45165

    using Windows 7:
    Just plug in the USB key and then run the SPnnnnn.exe BIOS file downloaded from the Web site drivers HP.
    Assuming that the USB is configured correctly (see below), Setup the BIOS sees the HP_TOOLS partition on the USB, copy of the BIOS and its file signature on the USB key, then run Setup winflash. The system BIOS detects the USB and the partition HP_TOOLS and the BIOS is magically updated.
    I put in place a new USB key as follows:
    1 rename the partition HP_TOOLS from the hard drive to something different like HP_TOOLSbak
    2. Plug the USB
    3. Download and run the utility to update the BIOS (not the BIOS, still) drivers HP support page.
    4. Select the option to install to a USB
    5. Select the option to create the partition HP_TOOLS
    6. The reader should now be formatted as HP_TOOLS with a record of Hewlett-Packard containing BIOS and BIOSUpdate records. The BIOS folder contains empty current, news and previous records.
    7 download and run the HP System Diagnostics (UEFI) MS drivers HP support page
    8. Select the option to install on a USB key. This will create a SystemDiags folder under the Hewlett-Packard folder
    9. Download and run the HP Notebook System BIOS update for the HP support page drivers, given that the USB is correctly tagged it will install the update of the bios on the USB drive
    10, we have to end up with a HP_TOOLS partition on the USB drive identical to the one that you removed from the hard drive.
    Once you have configured the USB drive, you can upgrade to other versions of BIOS (most recent or oldest) using this drive, as I mentioned above: just plug in the USB and then download and run the BIOS Setup program.

    Having said that I'm not sure of what you do, once you boot the USB drive.

    Hello

    It's really easy buddy.
    You must boot from the Toshiba recovery disc in order to start the recovery procedure.

    But note; the recovery disc formats the entire HARD drive. So if you have important data on your HARD drive and save it first.

  • How to use Apple Watch to take weight?

    A lot of people talking about how to use Apple Watch to lose weight, but how about the point of taking weight! Does anyone know how to use Apple Watch to take weight? It can track calories from the body, not the calories to burn track!

    Thank you.

    Yes, the shows follow the calories you burn. And it's good information, no matter what you try to do it. Apple Watch is not really to lose or gain weight. His focus is on getting in shape. It is not follow the weight at all. It follows the activity. Even if you want to take the weight, you still want to be active and in good health. Consult a nutritionist for what you should eat. Download an app like MyFitness Pal, which will allow you to set a goal and track your consumption.

  • Save to PNG using IMAQ file write file does not save good Gray Scale

    Hi - I have a simple VI which reads a raw U16 file and then try to save the option IMAQ write PNG file (because I want the 16-bit format).

    I defined a custom color table which is just opposite of gray, and this is applied to the image.

    The Image displays properly, but saves the PNG file with non-inverted grayscale.

    U16 RAW file is titled "Martha 1849-02-001-6 - view0000_raw_grey_16bit.raw' and sent to ftp://ftp.ni.com/incoming. "

    How is it and how do we get this working correctly?

    Thank you

    No! your custom color table to display the images, not apply to the image.

    In additional, it cannot save the palette as well as the 16-bit image. The pallet can be stored with 8-bit 'indexed' image.

    What you can do - if you need just reverse gray, use IMAQ opposite to calculate the negative value of an image.
