• queues the IMAQ image data type

  I'm trying to run multiple queues in the same loop entering IMAQdx images from several cameras, and then save to AVI. After reading the site nor a little, I discovered that the reason why I get only the last image of each bucket, repeated on all frames in the AVI file, is that the IMAQ image data type stores only the memory location for the image, not the image itself data. However, I don't see a better solution for the queues of the actual image data. What conversion could be the fastest / are in charge of the processor the lowest?

  

  For each image you must initial Image space.

  You can use something like this:

  

  You need to add initialization camera (s) and AVI. You must add the multicamera feature. Stop recording is missing.

• 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.)

• For an IMAQ image, how is calculated the size of the area of alignment to the left or to the right?

  For an IMAQ image, how is calculated the size of the area of alignment to the left or to the right? My initial assumption of the diagram

  http://zone.NI.com/reference/en-XX/help/370281M-01/imaqvision/imaq_getimagepixelptr/

  is that the left and right are equal. But that doesn't seem to be the case. Can someone tell me the magic formula? A combination of the border width and the width of the image?

  Thank you...

• 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...

• 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

• Contact information for return pixel Imaq image with the mouse click event

  Hello

  I'm trying to get the coordinates in pixels of an image Imaq based on a mouse click event, similar to this post and this post. The problem is that with the first post, I get the coordinates in the image control and hesitate to trust them, they seem to have the Center origin, may return negative coordinates and do not represent the actual size of the detector that I use (512 x 512). It also returns the coordinates outside the actual data when it is clicked on the image control framework. The second method returns simply null coordinates. What I want are the coordinates of the pixel displayed when hovering the mouse imaq image control framework.

  What baffles me, is that I tried the second method with a png stock file and it works fine, it is only when I create an image from the data of my camera than the coordinates are returned null. Note data views of camera under control of image very well.

  Any ideas would be useful. Enclosed is a picture of the offending code and the Panel before displaying the camera data is coming (I know it needs some cleaning).

  Thank you

• How to save an imaq image starting from a continuous stream, like a snapshot

  Hello

  I spent hours trying to find a solution for this on the internet for what I think should be really simple:

  I have a camera that gives me a stream of images, which I show in a chart of the image.

  Now, when the user clicks a button 'save', I want that picture that was shown at the moment where the user was hit 'save' is recorded. However, the user is prompted for a file location and name, so some time passes between hitting 'save' and write the image to disk.

  Meanwhile, the new images will be at the position of the pointer in the image that I wanted to save.

  It is clear to me why this happens, but how about him?

  I tried to make a copy copy Imaq, but this will give me just a new pointer that is always related to the old.

  I tried to convert it to an array, the same effect.

  I also tried writing a queue that contains a single element that has a buffer of image. The queue was not in a loop (which of course would replace the picture there), but again, the queue also just seemed to save the position of the pointer, while creating a new blank image in advance and I copied the image that I want with Imaq copy in this image buffer.

  So, how to store the actual image (not pointer) in memory to save a few seconds later?

  Basically I want something similar to what does the 'snapshot' of the curve of the image function.

  Any ideas?

  Thank you very much!

  Hello

  Thank you very much.

  I consider your solution already, however, I thought it's kinda an overdose.

  For some reason any, I don't know, he now works as I wanted. See example below (really just, I always wanted a picture).

  The only difference from what I tried earlier, is that now I did not specify the data type and the size of the new image... do not know if this is the reason why it did not work.

  Uday thank you very much for your help!

• IMAQ image for intensity 3d plot

  Hi all

  I know it would be an easy question to answer for most of you, but it does not give a moment difficult here. I want to build a simple laser beam Analyzer in my lab (see attached vi). My problem is that, ideally I would want the 3d plot (which is gray for now) false colour (a bit like the one illustrated in the exemple.jpg). Anyone have an idea on how to do it?

  I included in my attachments a real picture of a beam, in the case where you want to run the code. Please excuse the messy code, this is the first time I work with the palette of the IMAQ and I just wanted to see what we can do with it. Please tell me if you need more info and thanks in advance

• How an image IMAQ transformed into table, divide it into two parts and show them as IMAQ image after?

  Hello

  I currently use the vi IMAQ to get a real-time picture out a camera with 1024 * 1024 pixels.

  What I try to do is:

  (1) get the image IMAQ (OK)

  (2) put it in Array (OK)

  (3) get 2 smaller bays, each containing half the lines, a high-ranking, the other a low ranks (not OK)

  (4) do some calculations with these tables (come / divide them) (not OK)

  (5) display the resulting table of calculations as a map pixels like the first image IMAQ XY, I had (not OK)

  Could you please guide in the resolution of the present? I'm confused litle...

  (Step 3), I realized that the use of the VI "remove table" could be good, but I do not understand how to select half of the lines (high or low)

  (Step 4), I think I won't have any problem to do.

  Step 5) this one I'm lost, I can only trace some waveform, but never a card-pixel XY as the IMAQ

  Thak you!

  I think it is just a reference to the image (that is, as passing in a blank canvas). For example, I think you could re - use your image IMAQ coming - you might like it for reasons of performance, or because she puts up things like the size of the image / canvas. It is not very well explained in the documentation, but if you look at a few examples IMAQ integrated, it might be useful.

• Problem flashing with live viewing with IMAQ Image display

  Hello world

  I am writing a program for live imaging with camera Andor. I use some examples from Andor. The images are acquired in sequence and send in Image IMAQ and also graphical intensity display. There is minimal flicker issue in the graph of the intensity, but it is very bad flickering problem in display Image IMAQ. Maybe I wrong understand how to optimize vision tools. Does anyone know how to fix this? I enclose the code that I have tested. Thanks in advance.

  Best regards

  Han Yen

  HI Han,.

  You should try a right-click on the screen and choosing "snapshot". Who help me? In addition, you have a while loop nested in a while loop and the Interior more than while loop I see you have a Subvi I have not (GetMostRecentImage16) according to what is in this VI, this could slow down things - especially since the chart and display have to wait for the most secret while loop at the end of execution before the update.

  You can remove the inside while loop?

• 'Create a Subvi' movements labels (LV2013) IMAQ image controls

  Hello

  I noticed a strange behavior in LV2013 (x 64 and x 86) what SubVIs creation from a selection containing Image IMAQ son:

  The labels out of place of obtained characteristics Subvi on IMAQ controls/indicators, see the illustration below.

  This VI

  

  is impaired by creating a Subvi for copying and masking as follows

  

  The Subvi created has a façade that result that looks like this:

  

  All labels on IMAQ orders/lights are completely irrelevant. I couldn't understand, what appears to be a function of the new position of the label. In any case, it is quite annoying, because labels sometimes moving out of the main visible portion of the public Service and you have to go and look for them (through the window). -You must identify all the labels with the command/indicator to put everything back in place.

  One of my colleagues has confirmed this behavior on a different windows PC, using the same version of LV in x 64 and the same version of Windows 7 Pro)

  Of course, a simple method of MoveToDefaultLocation on all PS elements cause they go where they are expected to be, but how tedious... I remember not such behaviour in LV2011 where I used 'Create Subvi' loads of times with IMAQ Vision functions.

  I'd be happy if someone such color in it. Thank you very much.

  Cleaning of façade create a Subvi is performed, but it's not explicitly change the position of the control and indicator labels. There seems to be a bug in VI server when setting the position of the refnums IMAQ. This bug is independent of the function to create a Subvi. When writing of the 'Position' of a refnum IMAQ control property, the label seems to throw himself in a weird position. I've not seen this with other types of control with other controls, their labels always remain in the same relative position when the control is moved.

  I'll drop a CAR against the Position and IMAQ refnums property. In the meantime, you can use the VI attached to this post to solve the problem. Follow these steps in LabVIEW 2013 or later:

  1 copy of the VI attached to the following location: [LabVIEW 20xx] \resource\plugins\CreateSubVI

  2. restart LabVIEW.

  Once you have done, the position of the label IMAQ refnum to correct every time that you perform an operation to create a Subvi.
