Frame Grabber

Es nesesario utilizar un Frame Grabber para una aplicacion con Vision Builder?
Estoy buscando una de las camaras que se ofrecen en esta pagina y una marca ACE parece ser la idonea, sin embargo en accesorios me aparece que se requiere un frame grabber, es nesesario? (No voy a utilizar una Smar Cam),(la inspeccion que debo hacer es aproximadamente cada 6 segundos)

Que tal julio1111 Buenas Tardes,
Para esta aplicación te recomendaría mucho que llamaras a nuestros Ingenieros de ventas internas(Consultores) quienes te pueden apoyar en la selección de tu sistema según las necesidades que tengas. Puedes llamarnos de manera gratuita a los teléfonos que encuentras en la página principal de ni.com seleccionando tu país en la parte superior del lado izquierdo y ahí mismo viene la opción para comunicarte con nosotros. Nuestros ingenieros dependiendo de la aplicación podrán recomendarte si es necesario utilizar un Frame-Grabber depende mucho de la velocidad y el tipo de protocolo de la cámara.
Cualquier otra pregunta quedo a la orden.

Video acquisition from frame grabber

I wanted to acquire image from a video camera which only has analog output. To do that, I used a framegrabber, called :"Hauppaugel analog video giditizer".
However, as I can see from the list, the framegrabber provides image with YUY 2 format and in the list of my Labview vision module, I could not find such type.
I have written a code for acquiring image which works fine with normal web cameras. however, when I want to use it for acquiring the image from frame grabber, it gives following errors:
1. Error code: 1074396120 Not an image
2. Error code: 1074396015 Cannot connect to camera, it may be in use.
I guess it has something to do with the formats of the picture, but I really don't have experience with that. Could you help me out? The code is attached.
I lookforward to your advice and thank you in advance for the help.

Hello,
First, you have to know that your camera must be Direct Show, otherwise, you won't be able to use it in LabVIEW.
If it is compatible, then you will be able to grab image using IMAQ USB, but keep in mind that this set of VI is no longer supported as IMAQdx is fully compatible with DirectShow cameras, and much better than IMAQ USB.

Labview won't believe that my frame grabber board is configured?

Thank you in advance for any help
I am new to labview. I am sorry if this is a silly question, but I have worked on it for hours and haven't been able to find the solution.
I am using a NI-IMAQ PCI-1422 board to aquire images from a Pulnix TM 1020 camera. I can successfully see the camera from both the MAX and IMAQ vision builder. When I go to the DAQ Solution Wizard in Labview it says that "You have no DAQ hardware currently configured," and it sends me back to the Measurement and Automation Explorer 3.0 It looks configured to me and all my attempts to configure it more fully didn't make the system happy so I don't understand what else I need to do.
Also, where are the instrument driver VIs f
or this? Do I already have them hidden somewhere or do I need to go and download them?
Any advice that you could give me would be greatly appreciated.

Also, in case you are bored, here is an overview of what I am trying to do. I want to write a labview program which will allow me to specify a delay in seconds and then have labview acquire a an image from the frame grabber board and save it to disk, wait the specified delay period and then acquire and save ...

Anita,
Since you are using an NI-IMAQ PCI-1422 board you will not be able to use the DAQ Solution Wizard. Your board uses the NI-IMAQ driver software instead of the NI-DAQ software. You will want to use the Vision VIs which can be found by right-clicking on the block diagram and selecting Functions->All Functions->NI Measurements->Vision.
You can find some LabVIEW examples by checking your LabVIEW directory and navigating to the Examples->Vision directory. You can also find these examples by using the LabVIEW example finder by navigating to Help->Find Example
I have attached a helpful excerpt from an online knowledge base. The full knowledge base can be found pendocument >here. Please post back if you are still having troubles!

Is the NI 1426 frame grabber compatible with a Line/Linear array scanner?

Is the NI 1426 frame grabber compatible with a Line/Linear array scanner?
I am currently doing a feasibility study of project which uses NI 1426 frame grabber and a Linear Array Scanner, and I would like to know if they are compatible with each other.
Thanks in advance
Sandeeo
Solved!
Go to Solution.

Hi sandeepchinni,
I agree with gunnesjr that we need more information about what you mean by Linear Array Scanner. Like he said if it is a line or area scan camera then yes it will most likely be compatible. A little correction from what he said. You do not need to purchase NI Vision if all you need to do is acquire images. The framegrabber will come with the software that is need to work. If you need to do any kind of image processing then you will need NI Vision. The following knowledgebase lists what is installed with driver for the card. Which Vis are Installed with NI-IMAQ and Vision Acquisition Software?

Camera frame grabber to laptop

Hi everyone,
I am using a frame grabber connect a camera to a laptop. The camera is Dalsa Piranha2 linescan, it is said that programmable integration time, line scan rate,... and there are commands for this through serial port. Can you show me how to send these command to changes camera parameters? How should I do that in Labview?
Thanks
Hannah

Hi Hannah,
if this properties are settable through serial port, you can first check to send this commands through hyperterminal. If this works see the shipped examples "Basic/Advanced Serial Read and Write.vi".

Converting images from a Matrox frame grabber to LV?

How can I convert an image captured with ActiveMIL Lite from a Matrox frame grabber to an IMAQ Vision image?
I grab the image in LV using the ActiveMIL Lite functions. After that I will analyse the image using IMAQ Vision. So I have to convert the Matrox image to a LabView Image.
Thanks for help

Uli,
I believe Graftek Imaging has LV drivers for Matrox frame grabbers. You can call Robert Eastlund at (800) 441-2118 and he will be able to help you.

Need information on USB frame grabber Labview compatible (planning to buy)

Hello all,
I am looking USB based frame grabbers which are compatible with LabVIEW only. I need atleast 50 frames/sec acquisition rate. I am using PULNIX P2013P analog or monochrome CCIR camera with LabVIEW 8.2 version. Please suggest me any of such frame grabbers even third party products if they are available and also only compatible with LabVIEW.
regards
visu

There are no USB frame grabber cards provided by NI. The only form factors that are supported for frame grabbers are PCI, PCI-e and the PXI platform. If you are interested in using USB cameras, then all you need is NI-IMAQ for USB driver (the driver is not officially supported by NI) and a USB camera that is supported by the driver.

How to remove noise on images acquire from Digital 8 VCR to PCI-1409 frame grabber ?

I have some constant noise in the form of a discontinuous white horizontal line running accross the top of images which were grabbed from a digital 8 video signal. I have tried all the settings in MAX to remove these and have check the integrity of my connections, but to no avail ?

Kyle,
I found that adjusting the acqu window did the trick.
It seems that all the video i have on Digital 8 tapes gives me the same problem. When i use the camera directly to the frame grabber there is no problem.
In due course i'll try another camera with the Dig 8 VCR and compare these output picture quality.
Thanks for the advice,
Fraser

Has anyone been able to use a DataTranslations Frame grabber with CVI? I am trying to use a DT3152 in place of NI1408 frame grabber...

DT does not provide drivers for this hardware to interface to CVI or LabView. Has anyone had success?

you can find a LabVIEW driver at:

Automation Open (CoCreateInstance) with BlackMagic DeckLink frame grabber

I am trying to interface BlackMagic frame grabber hardware that has a COM driver. The C++ demos for the driver work flawlessly, but I fail to access the COM components from LabVIEW. The driver is initiated in C++ with
CoCreateInstance(CLSID_CDeckLinkIterator,NULL,CLSCTX_ALL,IID_IDeckLinkIterator,(void**)&pIterator);
As far as I understand the corresponding LabVIEW command should be to use Automation Open with either CDeckLinkIterator or IDeckLinkIterator as automation refnum. However for both refnums LabVIEW returns an error when executing Automation Open: Error 3005 occurred at Automation Open: Object specified is not creatable.
When I look at the demo code provided with the COM driver, there are really two COM commands that are executed before the CoCreateInstance
AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0)
CoInitialize(NULL)
Does anyone have a clue why the Automation Open might be failing in LabVIEW but CoCreateInstance is not failing in C++. Is there a possible workaround? I have tested this with both 64- and 32-bit LabVIEW 8.6.1.

Hi,
I made some progress...
I found a response to my first question in the forum, with a link to :
http://digital.ni.com/public.nsf/allkb/6EC98441BFAF93A486256DCD000179A2?OpenDocument
so the solution of this problem is in snipet decklink1
My remaining problem is about the configuration of the callback. It doesn't seem to work like in LV examples, or forum examples, as I cannot reference my callback VI as the callback function, and I get no event in the 'register for event' node.

NI PCIe-1433 Camera Link frame grabber programming using VC++

Hello, I have a Basler Camera Link-compatible camera and they use the NI PCIe-1433 Camera Link frame grabber as the image acquisition device.
Right now, I want to develop some applications on that camera and need to do programming on the NI PCIe-1433 by VC++.
So I want to know where I can find the software development kit for the NI PCIe-1433. For example, I can control the camera to grab the image by using the different functions(such as imgGrab(), or somthing like that ) from that software development kit.If there are some sample code that would be better.

Hi Wrsbj,
The IMAQ functions that you mentioned are contained in the IMAQ driver, which is used to acquire from Camera Link frame grabbers. I would also check the compatibility chart, to make sure that you get the version you need. As for example programs, you can take a look at this KnowledgeBase article concerning building and running the IMAQ examples in VC++.

Control exposure time and gain with FPGA as frame grabber

Hi,
I'm using a Basler acA2000 340kc camera with a PCIe1473R FPGA as frame grabber.
I managed to obtain images succesfully by modifying some of the sample codes. I can also control some of the camera settings thorugh the Pylon software.
Nevertheless, I'd like to control the exposure time and gain in LabView.
Any idea on how to do this?
Thanks

Ultimate the serial port on the board is controlled by the code on the FPGA. There are shipping examples that provide the FPGA-side implementation of interfacing the serial port to a host-side interface, which then bridges it to a TCP port, which is bridged to a DLL called "clsernif.dll", which interfaces through the common "clallserial.dll" that Pylon can use to access the camera.
Depending on your needs, you could interface at any of these layers.
-If you need to do this with the ultimate in determinism, you could have the FPGA issue these serial commands directly as needed
-If can do it from the host CPU, you could modify the host-side code and send/receive serial traffic to the FPGA code directly
-You could examine the example code that bridges to a TCP port and simple write some host VIs that talk directly to it by opening a TCP session to the socket it uses.

Pcie frame grabber/capture card

Could anyone suggest a compatible (v4l support) frame grabber/capture card.
main concerns are that i dont have to write a driver/api for this card (instead i want to jump right in to writing some capture code), linux compatability and it must be PCIe x1 to x16 should be fine.
Any input connection, though I dont think i can do much with dvb-t/terrestrial..
Thank you!

All input sources are acceptable dvb-t/terrestrial.
Analogue/S-video/composite/vga/DVI/HDMI are all good
PCIe is mandatory, yes.
Cheers ;D
P.S. The frame grabber will be used to test my rtp project

I am using PCI-6033E IO card and i would like to send 5 volts (high logic ) to the trigger box. the trigger box will trigger the frame grabber card, that i am using for image acquisition.

Hello;
The first thing you need to figure out is the shape of the trigger pulse needed.
In case you just need a logic high TTL pulse, you can use one of the digital lines of your DAQ device.
In case you need a pulse train (multiple trigger pulses), you will need to configure one of the general purpose counters to accomplish that task.
You can find examples in both Labview and NI-DAQ showing how to program your DAQ board to accomplish both approaches.
Hope this helps.

Interfacing with Scion Image Frame Grabber?

I have a Scion Image Frame Grabber in my PC & am trying to control it via LabView Vision. Scion has no LabView drivers, but has a dll & SDK available. However, their driver expects C++ pointers as arguments & returns ptrs. My thought is to write a cover driver in C++ to shield labview.
Anyone have drivers for this, or experience with this frame grabber board?

Thank you for posting on the forums. While National Instrument's driver and native IMAQ support obviously does not interface to third party boards, if your board does include a dll that allows you to control the frame grabber then you may be able to get the board working in LabVIEW. LabVIEW has a few options available for calling dlls, and this is probably the route you will want to go, unless another user already has a driver for this board and LabVIEW available.
To get more information on calling dlls and interfacing to external code (particularly C/C++ code), then I would start by looking at the "Using External Code in LabVIEW" document. You can find this by opening LabVIEW, going to the Help menu, and clicking on "Search the LabVIEW Bookshelf..." This will ope
n a pdf document that links to other great resources, one of which is the large "Using External Code in LabVIEW" document. Glance through this manual and then other information/examples on ni.com/support for some help in getting starting in calling DLLs from within LabVIEW if you have never had experience with this before.
