Interpretation of data from stereo camera Bumblebee (PointGrey)?

Hi, first noted that I read the discussion at http://forums.ni.com/ni/board/message?board.id=200&message.id=11236

I am able to access the above stereo camera through my RESUME very well (using IMAQdx) and set it up through MAX. I am also able to access any of the cameras individually by using the option of Pan at MAX (I think I could set this on-the-fly by program, but I'll leave that for another time, less important now.

This is based on the information of PointGrey Research Inc. at http://www.ptgrey.com/support/kb/index.asp?a=4&q=312&ST=bumblebee

The same page also shows that if I place the stereo camera Bumblebee to use Format_7 Mode 3, the resulting 16 - bit image contains 8 bits of the camera on the left and 8 bits of the right camera. I checked (I think) that this is the case, since when I run a drain to the MAX with this mode, I am able to 'white-out' the display of the right camera covering the LEFT camera. And no, this camera no balancing light or such, as a confirmed it by covering the right camera.

So, my question is how can I retrieve this information? A simple matter of data manipulation, I think, but I'm stumped. For now I understand I probably can't do it using the screw IMAQ, would it be necessary to have a loop for, go through the binary bits and separate them? The info about what additional image, how do I know what it takes NOT to separate?

So conclusion, I have a thread of data type Image that contains a 16-bit image, and I would only split into 2 images to 8-bit based on the above.

Based on the advice of the manufacturer of the camera, I have extracted the appropriate data successfully, but now have a new problem, which I will present as a new thread.

For the record, I've used the IMAQdx get Image data VI to extract the raw (16 bit uint) image data and the split table with Decimate 1 d Array to two tables, their resize to the size of array appropriate 2D (640 x 480 for my case).

  • data from table 2d data

    I am using data socket server to send and receive data from my camera (a wave front sensor) on the same computer. The data I received is a variant, and I need to convert the variant type to another type of data that I can use in Labview for the calculation and furthur processing.

    Variant of data I've received a lot of attributes, and the attribute that I need is a 2D array. However, I see that the size of my table in Labview, but not numeric values. The indicator shows me

    4 attributes:
    'Centroid_Pos_X'-> [33 x 41]

    'Centroid_Pos_Y'-> [33 x 41]

    "Centroids_X"-> 15
    "Centroids_Y"-> 15

    These four attribute must all turn around a table, but they are all return me the size of the array...

    I tried 'get variant attribute' and also 'variant to data'... but impossible to get the correct data.

    can someone give me some advice?

    You perform an additional step that is not necessary. As I pointed out, the Get variant attribute function has a value entry default, whereby you can wire a 2D table for your table directly:

  • Moving video files from digital camera, date taken does not save

    On Win7 Pro I'm having a problem where when I move the files from my digital camera Canon or my Sony digital camcorder to HDD the date taken on the videos aren't save. It defines at the time I moved the hard disk instead. It comes to all the dates in the properties.

    It's only when I copy the video files keep everything file photo.

    This happens when I copy files directly from the camera or the SD card

    All the files on the camera are correct but none of those on the hard drive.

    Ok. I had trouble to transfer photos from my old computer to my new computer.  The dates and times on the pictures changed.

    I finally got the moved and kept the correct dates on each photo.

    That's what I did:

    1. I opened the 'Pictures' folder on the old computer and click on "Select all" under the tab 'Edit' at the top.

    2. then I went to the "Edit" tab and choose "move to folder".

    3. in the next window, called '' Elements to move, '' I found the file that I wanted to move the photos to and selected this folder and then clicked on "move".

    4. all photos have been transferred to the new computer with the date and time correct.

    5. However, this deletes all photos from the old computer.  But I do not really need them on the old computer since I will be recycling with Dell.

    We sincerely hope that this information helps someone else, since I had a hard time finding how to do this task.

    Good luck.

  • How can I sync 2 sony AVCHD images from the camera on the "date" as a prelude and import it in first pro?

    I have 2 sony camera popular with the AVCHD file structure. The two cameras are the same. How can I sync 2 sony AVCHD images from the camera on the "date" as a prelude and import it in first pro? Im working with 6.0


    Now I see the date taken in the import screen until I click "ingest". When in the trash, this option is there, but no metadata in there. It is therefore impossible to import images from two cameras and have these sorted.


    How can I get this sorted out before, so I can export for the first?

    Thank you. Tom van den Dool

  • Remove iCloud library remove my photos from my camera

    I want to back up my data but the I cloud photo library takes too much space so I want to know if turn off iCloud library would remove the pictures and videos from my camera, and I don't have a pc if you are using a computer would not be a valid solution

    I was wondering this too! I received an email from Apple as soon as I turned off my iCloud photo library, and he says: "You must download full resolution photos and videos at least one device before they are deleted icloud library within 30 days."

    "Photos full resolution" are pictures that have more pixels, compared to photos low low-pixel resolution. If you're wondering what pixels are and why they are important, they essentially affect the size and sharpness of a photo. Large, clear photo is a full/high resolution photo. A small blurry photo is a picture of low resolution.

    I'm sure this means that if you want the best and the most beautiful photos, you can let your iCloud photo library on. If you don't mind more blurry, less polite pictures, turn the power off. Keep reading, though, before you go turn off your iCloud library.

    Good, now that I've explained what activating / deactivating the iCloud photo library will do to your photos, I will give you the answer to your question:

    I don't think that the pictures on your iPad will be deleted if you turn off your iCloud photo library. If your photos mean a lot to you and you don't want to take the risk to remove, do not turn off your iCloud photo library. Turn it off and not turn on again in 30 pourrait delete your photos. I don't think he's going to remove them, but it could very likely.

    Summary of my response/TLDR: I do not think that your photos will be deleted if you turn off your iCloud photo library, but they might, so if your photos are very important to you (and you do not want to risk having to delete them), then keep it.

    Sincerely,

  • Transfer data from PvZ 2 old iPad2 again

    My son got an iPad 2 that he used to play Plants vs Zombies 2: it's all the time. He made a lot of progress and has also made several purchases in the game. Last September, he got a new iPad Air but when we loaded the game all its previous purchases and progress have disappeared and I have not found a way to get back them. With the new iOS, you can't have the file structure of the applications that you used to be able to do (thank you, Apple, to protect me from myself)<-- sarcasm)="" so="" i="" can't="" use="" iexplorer="" or="" anything="" to="" copy="" the="" data="" from="" one="" to="" the="" other.="" i="" just="" want="" the="" data="" from="" this="" one="" game,="" not="" the="" entire="" ipad,="" because="" he="" has="" other="" progress="" on="" games="" that="" he="" has="" since="" loaded="" on="" his="" new="" ipad="" that="" i="" don't="" want="" to="" erase.="" there="" seems="" to="" be="" no="" easy="" way="" to="" simply="" log="" out="" of="" the="" game="" on="" one="" device="" and="" log="" in="" on="" the="" other="" to="" get="" them="" to="" sync.="" i've="" tried="" various="" things="" through="" icloud="" but="" now="" that="" there="" is="" no="" "documents="" and="" data"="" setting="" there="" you="" can't="" do="" it="" that="" way="">

    This was a huge pain. You would think that in all similar devices, it would be a bit simple but fashionable Apple which is not the case. Does anyone have a solution for this?

    I was wondering on iExplorer works.

    The apple plan is for you your old device to backup and then restore it in your new device.

    It takes more flexibility by apple.  This is your camera.

  • Add data from serial Port in the indicator series front panel?

    Hello! Everyone,
    I'm new to LabVIEW but has prior programming experience.

    I have to develop a front for my camera and this is why I need LabVIEW, data comes from serial Port, so I started internet research / LabVIEW forums and found various tutorials by the help I am able to do the part Serial Communication, but has got stuck in one thing.

    Whenever data from serial Port, it gets displayed on the indicator chain but clears quickly, but I want some data comes it does not erase the old data and new data to add with the old data.

    I read the string concatenation will work in this case, but I am not able to use it.

    Please take a look at my VI attached to this mail.

    You must use a shift register to keep your story.

    I recommend you go to some of the tutorials available.  They will help you a lot to get off on a lot of things like that.

  • My scanner and Camera Wizard is not poping up to transfer photos from my camera

    My Wizard appears after using the trial version of AVG PC Tuner is no longer to transfer pictures at my cameras are listening on.  Used to.

    the wizard has no other camera listed... does not work try to list them using the disc that came with them... I have a Sony and a new Panasonic... dunno why no brand is not listed.

    Anyone know how to get the screen to make it appear again?

    I tried the automatic setting of Microsoft... has not helped... Impossible to find something wrong

    I have always used the auto pop up the camera wizard to transfer my photos from my camera.  I ran AVG PC Tuner trial a few days ago.  Now... the scanner and Camera Wizard does appear more... ugh.  I tried to add the two cameras to the wizard, but because Sony and Panasonic is not listed, I can add them (he claims he can't find good info on the disk is)

    Anyone know a fix?

    do a system restore to an earlier date of AVG from the trial.

  • pass data from childCardDone to a textfield in QML?

    I have a card camera call function that responds with the path of the image once a picture is registered using the childCardDone function.  I have no idea how to pass data from c ++ to qml.  I know that during the passage of the QML for C++ database, you set a QString & something.  How can I do the reverse?

    Here's my CPP code:

    void App::childCardDone(const bb::system::CardDoneMessage &message)
    {
        if (message.reason() == "done")
    
    //      Need the message.data() info in my QML
         message.data();
    
        qDebug() << message.reason() << "\n";
        qDebug() << message.dataType() << "\n";
        qDebug() << message.data() << "\n";
    }
    
            public slots:
            void childCardDone(const bb::system::CardDoneMessage &message);
    

    and I just want to get the value of message.data () into a textfield label in QML:

    Label{
    id: capturedFilePath
    text: <>
    }
    

    All help is appreciated and will be loved and accepted as a solution if it works.

    Thanks in advance.

    For use in your function you will need to decalre in the header.

    In the header to declare,

    AbstractPane * root;

    Then, change

    AbstractPane * root = qml->() createRootObject;

    TO

    root = qml-> createRootObject();

  • Old photos have reproduced after importation, the images from the camera

    Original title: pictures were reproduced during the transfer of the camera

    Hi - I clicked on import images from my camera to the computer that has been done successfully, but my old pictures exist duplicate? /?  I had checked before hand on the help page - where windows 7 stipulate that

    Why I can't choose which photos or videos to import?

    Windows detects your images and your most recent videos and is not a duplicate of the old photos or video versions that you have already copied to your computer, so you can import your pictures and videos in a single step. You can then view and organize your photos in the photo library. For more information on the management and organization of photos in the photo library, see Managing your photos. You can also view your images imported into the Windows Photo Viewer, where the large preview format makes it easier to decide which newly imported pictures to delete from your computer. For more information on the display of your pictures in Windows Photo Viewer, view and use your pictures in Windows Photo Viewer.

    To organize your videos, you can use the videos library. For more information about managing and organizing your videos in the videos library, see Managing your videos.

    Was it useful?

    If you could help with a quick method to remove all my duplicate photos I would really appreciate it.  I have nearly 400 of them

    Hello

    Did you use the functionality of Windows or all third-party software to import files previously?

    Sorry to hear that.

    When you import files, the same files will not be imported if the file names are the same. If you used a third-party software to import files previously, then the name of the file may be different.

    You can sort files by date and then try to remove the recently added files however, you should recognize the duplicate files.

    See the site for how to sort the files:

    Organize, sort, or group your files

    If you need help let me know and I'll help you.
