use of display and IMAQ image memory

Hello

I wonder how much memory is used when updating from imaq image display.

I need to display images (512 x 512 size) acquired by a camera in real time. But I don't necessarily need show each of them so that can save me some memory. The camera runs at 50 fps and I can live with display rate 5 frames per second.

Right now my image display is updated from the buffer (updated at 50 fps) continuous (Snapshot mode off). I guess I have 3 options:

1 use the lifestyle snapshot and say explicitly on the screen to update. Whenever the display is refreshed, a copy of the image is created. But I guess that the previous copy is destroyed at the next update. If this method costs an extra copy of the image in memory.

2. create an extra copy of the image that is updated only at 5 fps and connect it to the display of the image (Snapshot mode off). I think this is equivalent to method 1, with respect to the use of the memory.

3. in the State. No additional copies of the image is stored. But the display is updated at 50 fps.

Which is more expensive, update the display 10 times faster or holding an extra image even copy of the memory size?

Thank you!

It is not really a memory problem: you have an indicator to display images. Display an image requires additional resources, but there is no continuous memory allocation! Once the resources are allocated, the use of the memory of your application will remain stable. (Otherwise, something goes wrong and need to be identified and fixed.)

  • How to use text variables and the Image for printing

    I work for several months on the product with AS3 Configurator.
    I am not competent with AS3.
    Now, it seems that perhaps my design is all wrong.
    Is there a good way to do this?

    I have a main scenario that has video clips showing images of different options for the product.
    On the first image, I use buttons to select the choice for option 1 of the Option1_mc.
    Can I store the selection in a variable.
    I use a button to go to the next choice (screen 10.)

    On frame 10, I use buttons to select the choice of option 2 in the Option2_mc.
    It is stored in another variable.

    There are about 10 options that are selected and stored in variables.
    Some are text values and other images taken from video clips Option instances.

    I made a Print_mc to use to printjob.
    I can't get the values of the variables to display the first image for printing.

    Any helpl would be appreciated.

    You are welcome.

    you will not be able to insert a variable into a textfield.  you are going to assign to the text of your TextField property set to one of your points of variables to.

    Thus, for example, if you have:

    var var1:String = 'this is a test ';

    You can use:

    TF. Text = var1;

    I'm having a problem using the slideshow module in LR 6.3. The slideshow contains the background image as one of the images to display. Earlier, I have created a slideshow of practice and the background image was not displayed as an image in itself. How to make it behave?

    Another approach, perhaps a little more elegant (?). Create a collection that includes images for the slideshow. Include the background image in the collection. Drag the background image in the Panel to designate. Then, remove this image from the collection and create the slide show. I just tried and it works, too.

  • Emulator CVS displays bitmap color black and white images

    I use a VBAI2009 inspection on 1454 CVS which uses a camera firewire AVT Guppy F - 036C. This system is on a production machine inspect the product we make. VBAI uses the legacy IMAQ for IEEE 1394 on a CVS not the driver IMAQ-dx cameras. The VBAI script contains several steps function color inspection. To get the AVT camera to display the color, I had to install the files of MAX camera using the Bayer color tab because Bayer settings are not accessible from the driver on the CVS IMAQ. I'm no adjustment of the camera of the VBAI. This configuration works well and has worked for 6 months on the machine of production without any problem.

    Now, I need to edit the VBAI script but can't stop the machine to make the changes and test the program. I captured images bitmap using MAX during the inspection was installed 6 months ago and they stored on my host for just such an occasion. I am using these captured images and the CVS emulator in VBAI to make the changes to the program offline. I performed the inspection under the CVS emulator and the acquisition stage is configured to point to the captured bitmap images using the button Configure Simulation settings. The problem I have is that bitmaps are displayed as black & white in the emulator, even if these are images of color seen with paint. I can't find a way to fix this. Is - this problem as a result of using the parameters of Bayer to create the image color or something else in the emulator? The emulator, no installation of color image treats?

    Any help would be appreciated,

    Mark

    The stages of acquisition camera record video mode information used to acquire images. If you use these steps in emulation mode, it converts the type size and the image to match what has been gained for calibration and processing step use the same type of image. Looks like than the stage thought that the image was mono, even if you got it to be color. I will consider how it could have be saved incorrectly when you use the settings of Bayer. In the short term, you can disable the acquisition stage (don't delete so you do not lose the camera settings saved in step) and use a stage of acquisition of simulation or a new phase in the acquisition of 1394 and won't force the image size/type.

    Hope this helps,

  • Random HTTPS of image not displaying and be abandoned

    This is a file that includes pictures posted on my site:

    They are provided by HTTP and they work well.

    But in this file:

    https://polishwords.com.pl/dev/testAbort.php

    But I show the same images over HTTPS not HTTP and every time I refresh the page (CTRL + F5) one, at random, pictures is not displayed and in console network red poster with information: abandoned.

    I've tried it in Chrome, Internet Explorer, and Opera, and everything is ok. Only in the latest Firefox.
    I tried with deleted complete privacy, restarted several times updated FF, disabled addons, extensions disabled and it's the same thing. Another person who also has FF me reported the same situation.

    In my server log, it looks like this:

    Bad load:

    What is the cause of this behavior?

    Hi tomaszs, based on your journal, your Web server is receiving and responding to the request, but the small size of the response suggests that there is some sort of glitch. Can you spot any model it?

    Unfortunately, I'm no expert on web servers and I find encrypted traffic very stimulating to see - using a debugging proxy can work around the problem that you are trying to diagnose by managing connections differently.

    It is without doubt a documentation on when Firefox give up the demand for a particular item.

  • I have a few qeustions about IMAQ images and control charts

    First qeustion is: library in the IMAQ, you have the image control how can I possibly call the "Zoom to adjust" function thanks to a button, rather than with the right click because I tried it and I can't find anywhere so that claire KING simply is sided with the nodes to invoke.

    Second qeustion is: when you have a chart, how can you control the X value that you look with a numeric value that allows you to adjust the visibility graphic on some value x, for example, I make a numeric with a value of "10", I'll have the chart to access the value '10' so is it possible anyway I tried to work with some nodes of property but I get a little tangled in the web page of possibilities.

    Third Qeustion is: it is a qeustion minor but I would ask anyway why is that when you change the value of a button you can change only once in the structure, and not twice because I would like to have a button when this button is true it affects the other 2 buttons true and when it is false it affects other 2 buttons false... I can only get the effect to 'true' or 'false '. To complicate things even more if I still want to be able to use the 2 buttons that are defined differently by the first button, it's just if I can automatically start and stop the two buttons at the same time.

    and while I'm I also have a fourth qeustion: is there some way you can use the line tool several times in the section IMAQ image because the tool palette allows only 1 line.

    This VI use you to lines... is it "IMAQ Overlay line?

    Try the attached code...!

    And if it is a solution to your fourth question, then it seems that all your queries are resolved...

  • How can I use a function toolwindow or imaqBCGTransform on the image displayed by the image or the canvas area?

    Hello

    I use LabwindowsCVI8.5 & NI Vision. Recently, I met a problem when I tried to apply a toolwindow on diaplayed of the image by image or canvas block, the toolwindow successfully showed, but could not work. I knew that I can use imaqCreateImage & imaqDisplayImage functions to create the image on a new separate window, then, the two work well toolwindow & imaqBCGTransform, but I just want to know is possible to use the functions of Image processing with image display as part of the UIR or as a subgroup of experts? Coz I think it will be well conventional to see the image processed in this way.

    Thank you very much!

    URT

    I've always wondered why there is no control to an IUR for display of an image of Vision of OR...

    Anyway, there is a hack to incorporate a display image of NI Vision window in a Panel. It has already been discussed on this forum but I can't find the link more.

    It goes something like this:

    HWND window_handle, parent_handle;

    int image_window;
    int left, top, width, height;

    initialize the CVIRTE, etc.

    create the parent panel

    Panel = LoadPanel (...);

    get a new handle to display (optional, see the imaqGetWindowHandle documentation)

    imaqGetWindowHandle (& image_window);

    integrate into a parent group

    WINDOW_HANDLE = (HWND) imaqGetSystemWindowHandle (image_window);
    GetPanelAttribute (Panel, ATTR_SYSTEM_WINDOW_HANDLE, (int *) & parent_handle);
    SetWindowLong (window_handle, GWL_STYLE, WS_CHILDWINDOW);
    SetParent (window_handle, parent_handle);
    SetWindowLong (window_handle, GWL_STYLE, WS_CLIPSIBLINGS);

    Position the display where it should be displayed and resize
    imaqSetWindowSize (image_window, width, height);
    imaqMoveWindow (image_window, MakePoint (left, top));

    I hope this helps...

  • Using controls IMAQ Image in steps of LabVIEW

    Hi guys

    So far, I used TestStand 4.0 with LabVIEW 8.5 and Vision Development Module 8.5 with no problems. Recently, I've updated to LV 8.6 and 8.6 VDM. I started having weird problems when using LabVIEW steps with input/output containing IMAQ Image controls. When I try to click on such an approach in the seq editor or try to insert a new step in the sequence, the initialization step takes a long time (a few tens of seconds) or completely freezes. I also tried to upgrade TS to version 4.1, but no difference. Also, my colleague experiences very similar symptoms on the same software configuration. The only difference is that on his machine, it takes only a few seconds when you click on the step in the vision. However, the steps containing only not an IMAQ Image control behave normally, i.e. you will not encounter any "time initialization" when clicking on it in the sequence.

    To illustrate, I enclose a simple VI containing nothing more than a single Image IMAQ control. If you don't link to the connector pane, the VI works fine when it is inserted in a time of TS. If the Image IMAQ control is bound to the connector pane, TS freezes when inserting such an approach.

    The problem that causes this problem has been identified.  More information is available here: with TestStand and LabVIEW 8.6 known compatibility issues

  • Images lost during operations cut-and - paste from memory card on my computer

    I was moving pictures on my memory card in a folder in "my pictures" using the cut and paste.
    on my memory card and when I plugged my camera into my computer, the photos were in different files as the memory card has been put in two cameras; a samsung and a cannon. Some of the pictures so share the same name of the image.
    When I cut and pasted the warning came to say something in the sense of 'element already exists, replace the existing file' I clicked on "Yes to all" without thinking about it, and now I've lost the almost all of a folder of photos! And because they were cut out of the memory of the device, I can't think of a way to get back them.
    I tried many searches in my files to try and find / recover, but I have no idea where they would have gone!
    They are pictures of vacation and I really want to try to recover, any help would be greatly appreciated!
