Hi everybody,

I need your help because I have a big problem and I don`t understand why...... But I hope it is easy to resolve.

I searched but found nothing.

 

I have this kind of error

 

But I don`t understand because I have two software, the first works very well, So I just copy this code to put in the second software, just to record one video.

Everything it`s the same but with the second there is this error message.

this software works very, whitout problem.

And this software, you cansee it is the same code, doesn`t work

 

I can`t understand why really..... I try to change the format of the imaq, or use IMAQ cast imag, but whitout results.....

If someone can help me

 

Thanks a lot in advance

Hi all. i am using vision builder .

 

Here my application will acquire image (GigE) and store it to particular location .

 

Once i do continuous run the CPU usage become above 50%.

Hello

We have the Flir T600 camera, the Flir Toolkit (3.3.10) for Labview (2014) and the SDK from Flir. The camera can only be connected via USB. I have also tried to install IMAQ, but I can`t find the tools in Labview, the tools of the Toolkit are there. Do I need IMAQdx or the complete VAS for this camera or is IMAQ enough? How do I get the tools?

 

I want to get the images or record a video, set mesurement points and read out the data.

 

Thanks for your help!

Dear All,

 

I am working on creating and writing frames on to AVI files. I need to start writing frames up on record on command and close the AVI file up on record stop command. I am trying to read frames from an recorded video and write in to another AVI file.

 

But i am observing Error 1074396005 invalid avi session, whenever i run the code. I am using AVI2 VI's (IMAQ AVI2 Create, AVI2 Write and AVI2 close).

 

I am using LabVIEW 2013 SP1 and Vision development module versions.

 

Below is the block diagram for reading an avi file and writing in to avi file upon record on command (numeric control value 1 to case selector) 

 

Block diagram for record off

 

Below is the error observed:

 

Kindly suggest what would be the possible reason for the error.

 

With regards,

Sri

I upgraded to VAS 2014 SP1 (I noticed this issue with VAS2014 as well) and I cannot rename the IMAQ Interface Names anymore through MAX.  Previously I would right-click on the interface (NI PCIe-1429 "img0") and select "Save As..." and then change the name to the interface name that I want to use (for instance "img2.iid").  After the save, the interface name is still img0.  I've tried restarting MAX and many other things but it seems to only allow the name that it assigned.

 

I use multiple frame grabbers and I want to be able to assign the names so that it is less confusing (to me and to others).

 

How do I change the Interface Name to the one I want?

 

Thanks,

Bruce

I want to use an Allied Bonito CL-400 camera to acquire a movie at a fixed frame rate of 500 fps (an image each 2 ms). I need to have a controlled application, meaning that I need to know when each frame was acquired. How can I do this in Labview?

Currently I am acquiring the movie using the extract buffer vi inside a while loop and I am also saving the time by using the tick counts. What I noticed is that my datarate oscilates whitin 1,2,3 and 4 ms (see iteration times in im3). Also, when I open my camera in MAX I see that the datarate oscilates around 500 fps.

Thanks

Hi everybody,

I have a little problem, I`m sure it is easy to resolve but I didn`t find the solution.

I have my first which use to open and close the gates..... But all the stuff is in a box, I can only check inside with one camera.

I would like to be able to see inside the box with my camera to be able to open or close the gate when I have to.

That`s my main software:

 

And I would like to add the code to acquire the images.

I know how to witte this code, but when i tried to add it. there are some problem. I can not see the picture pr use the motor.
Anyway I don`t know how to include the acquiring software.

Thanks you for yours solutions ^^

Hi everyone,

 

I'm having trouble to acquire a good quality picture of an object to search for cuts, scratches and holes, the object is a completely reflective cilinder. until now i've managed to get a good picture but the reflection of the camera is way difficult to delete with lighting. The current lighting technique i'm using is a Dome lighting:

 

 

the best picture i took:

That black particle is the reflection of the camera, What technique or type of lighting or trick can i use to get rid of that reflection?

 

thanks in advance

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!

Hi Every one

In my simple example, I have 2 two while loop.

I want to asquistion Image in a loop and tranfer image to another.

So, I used local Variable to do that. But It tranfer first image, not continuous image. ( I record video by webcam)

How can I Fix it?

Hi All,

I have a collection of data that comprises of 2 classes, however, the number of samples for one class is much higher than the other. 

I found that this will cause an error during the training of the SVM as written here 

I know how to use the SVM vi's in LabVIEW, however I dont understand how can I weight the samples of one class more than the samples of the other class in IMAQ train SVM?

How do I use the parameter Weighted cost?

Do I just give a higher value of weighted cost for one class than the other? If yes, then how can I figure out how much should that higher

value be? Or is the weighted cost value set  based on trial and error method?

 

Thanks,

Regards

Aveo

Hello NI,

 

We are testing our camera with your NI MAX.

We comply with USB3 Vision Protocol.

Our camera is passsed via Matox S/W.

Currently We are testing our camera via NI MAX.

but in the NI MAX, our camera is not operated.

Current State..

1. XML OK

2. Register Read/Write OK.

3. Payload Size : 16272720 Bytes

4. Width:4660, Height: 3496

 

But NI Max doesn't send the command (ISO Enable/ Stream Enable)..

Why does it happen?

 

Regards,

Nick.

Our company is to make the machine vision camera.

I would like to know whether our camera is compatible with usb3 vision or not.

Does NI MAX have the compatible checking S/W Tool about USB3 vision?

I know the NI has the compatible checking S/W tool about GigaE vision..

Dear all,

 

I was wondering if it is possible to connect some CNC machine and NI Smart Camera via PROFINET?

 

What I've found is that I can connect this machine to PC using a COMSOFT Board and then create some LabVIEW software on PC, but I want to implement my software in Smart Camera and connect it directly to CNC machine.

 

Kind regards,
Marcin
