Which is better for usb camera between VISA and imaqdx in labview 2010?

i have done a program for usb camera to acquire images with imaqdx.
now i want to know which is better between VISA and imaqdx in labview 2010?
i didn't study visa before
thans for help.

VISA is primarily used to communicate with instruments via GPIB/TCP-IP/Serial/USB. In order to use easily VISA with an instrument over USB the instrument must adhere to the USBTMC spec. A camera is not likely to have this. Otherwise you have to use USB RAW, and that requires detailed knowledge of the data that is transmitted by the instrument. Manufacturers rarely give this information out. Normally they will provide a DLL to communicate with the instrument.
Thus, in your case, VISA is not going to be an appropriate API to use for a USB camera.
Out of curiosity, what prompted this question?

which is better for educational purpose ( for attending online classes ) ?? iPad air 2 or d macbook pro?? what abt iPad pro ?? plz suggest one for me plz

Some educational site are behind the times. At times, they require software that isn't available on the ipad. You should visit an apple store and try the educational site with the ipad. Considering that you have an iMac, I'd lean in the direction of the iPad.

Which is better for gaming and why?

Hi,
I was researching budget gaming laptops(around $1000, INR 55000) and came up with two choices.....
1)HP Pavilion g6z-1d00 Notebook PC
http://shopping2.hp.com/en_US/home-office/-/products/Laptops/HP-Pavilion/A2B39AV?HP-Pavilion-g6z-1d0...
2)HP Envy 14-2130nr Notebook PC
http://shopping2.hp.com/en_US/home-office/-/products/Laptops/HP-ENVY/QE295UA?HP-ENVY-14-2130nr-Noteb...
Could anybody please tell me which is better for gaming (main purpose and best performance)?
The HP Envy looks great but I don't know much about AMD Quad Core.....
Also, is it possible to upgrade the graphics card on the HP Envy ( AMD Radeon 6630 to a better one) via a HP centre?
It seems to run most games quite well, but I need it to be able to play new games for at least 4 years more (college), while not factoring in the costs for any possible graphics card upgrade....
Please help!!

Thanks Huffer _ very useful.
I wasn't aware that there was a heat problem with the i7 processors, my dv8 runs at around 42 to 52 degrees, mind you I don't really put it under much load. I use it to play Blu-ray ISO files on my projector and for photo editing (Adobe CS4), it's an 820QM.
I have also changed the thermal compound to ICDiamond and drilled holes in the speaker cover to improve air flow, that made a difference too.
@ abhishekmaha
Don't take my comment to seriously, although I think it has some truth to it, it was meant to poke a bit of fun at you.
Heat has always been one of the biggest factors when it comes to any computer, designers try to make them thinner, lighter and cheaper and those types don't work for gaming very well. They're OK for the occasional one, but not on a regular basis. I believe that if you game on any machine that was not meant for it, you will not get 4 years out of it _ 2 years.
I wish I could tell you different, but I am not going to lie to you.
Heat basically affects 3 things on a laptop, the solder that holds the components on the motherboard, any mechanical moving parts, eg the hard drive, fan _ and the battery. You can remove the battery to prolong its life when gaming.
Heat breaks down the solder over time and the mother board simply stops working as far as the hard drive, it stops spinning because the tiny bearing(s) in there dry out and seize up.
If you don't want to use a cooling mat then prop up the back of the laptop, hanging it over the edge of the table will expose the fan intake, but will block off other vents.
60 degrees is a bit warm too, 50 is better or rather, the cooler the better. What ever machine you get, make a note of what the temps are when you first boot up and when it's hot. The idea is to get an average so you can judge when it is dangerously getting hot.
P.S. Be sure and give Huffer a kudos too.

Support for USB cameras in VBAI?

NI have a free driver that allows Vision 7.1 to access USB 2 cameras. Is there anything similar available for VBAI that would allow me to use an industrial USB 2.0 camera?

The free NI-IMAQ for USB Cameras driver is meant to support simple USB webcams that use DirectShow. For machine vision or scientific imaging applications, most USB cameras don't have the performance or the features needed, like triggering. The primary "customer" for the free driver has been universities that use webcams in labs.
With that said, there are a few industrial USB cameras out there that can be used for machine vision. The problem is tha there is no industrial USB camera standard that covers them all (like there is with FireWire), so companies like National Instruments would have to provide and support different drivers and software tools for every indutrial USB camera.
A better solution is IEEE 1394 (or FireWire). They offer the same performance as USB 2.0 cameras and are around the same price. On top of that, almost every large industrial camera manufacture has a line of industrial FireWire cameras (including Sony, Basler, FLIR, and Cohu), and they all conform to the same DCAM (or IIDC) standard. WIth this standard, our one driver, NI-IMAQ for IEEE 1394 Cameras, works with all of them.
Vision Builder AI is designed to solve machine vision applications without programming, while USB cameras usually don't provide the triggering or advanced modes necessary for machine vision. Because machine vision and USB cameras don't usually go together, we didn't provide support for USB cameras within Vision Builder AI. My question to you, another_novice, is why would you like to use a USB camera with Vision Builder AI? Are there particular features in a certain USB camera that you can't find in other cameras? I would really like to know so we can get a better picture of how our customers are using our products.
Thank you.

IMAQ for USB cameras error -1074396024 system error

Hi,
I used a IMAQ for usb cameras.vi. It works well in my laptop which is a newer one. Well, when I changed to an old one computer and ran it, the error shows that system error, i.e. -1074396024. Could you tell me what it means and how to fix it?
Thanks.

Hi,
I tried to use MAX to configure the Dazzle card, see the attached file. It says that it does not have any video mode which is supported. Our camcorder has the analog signal output. Is it due to the camcorder problem or this Dazzle USB converter problem? Thanks.
In addition, I am wondering if this IMAQdx can configure this camcorder from the error.

From Analog CCD to NI-IMAQ for USB Cameras?

I installed the NI-IMAQ for USB Cameras to obtain video feed from a SONY CCD camera in real-time. This camera only has the S-Video analog output so I used a Plextor PX-TV100U A/D converter to transform this signal to USB feed. It worked at first but after running my Vision VIs a couple of times NI-IMAQ could no longer establish a connection with the camera. And as I shut down my LabView 8.5, the whole computer rebooted automatically. The error messages from LabView 8.5 varied from "Not able to establish a connection to the camera... might be in use" to "No video driver installed...". None of it made any sense because the VI worked sometimes without errors. And the same thing happened to all three computers in my research lab at Tufts University.
I realize that my camera is going through a signal conversion before the USB, but why would NI-IMAQ for USB Cameras crash the whole computer? Also, is there a way to control my camera shutter speed from NI-IMAQ? I thought perhaps the camera wasn't setup right for the image acquisition. Help!!

Hi HTL,
IMAQ for USB only works with cameras that are DirectX compatible. Can you be sure that the information coming out of the A/D converter is compatible? Also, when you say "it worked at first" what exactly do you mean? Were you able to do image processing on images brought in via the camera? If you had Measurement and Automation Explorer (MAX) open and the camera selected at the time you tried to run a program that called the camera, you should get an error like you saw (Not able to establish connection).

more than other versions...

Which is better for bulk message scenario in sap xi RFC or Proxy

which is better for bulk message scenario in ( RFC or Proxy ) ?
Edited by: prabhatxi on Aug 6, 2010 4:44 PM

Proxy will alwaays be better option in this case, as it is adapter less framework, and communication happens directly with XI central integration engine. So it is always fast communication and gives good performance.
But still you should consider other factors, you may consider using RFC as well, as sometime we go for RFC/IDOC as this are the standard interfaces already available rather than creating structure...
May be you can share more info on what type/volume data are you planning to send via XI?
Hope this cleart your doubt..

For some reason that link I gave you isn't working right now, but it was today, weird. I would get Tomcat simple because sun uses it in its examples and recommends it. Here's sun's link then, it's probably more useful anyway. http://java.sun.com/products/jsp/

Which is better for newbies, Jgrasp or Netbeans? I need something that explains errors more thoroughly than Jgrasp.

Here's my code with 3 errors. Now bear in mind that my program has compiled completely and ran correctly up to this method. All I'm trying to do with this method is get the average of all grades in a multi-array. I researched and found some code that was similar to what I needed to do but it's not working out yet. All other methods in my program work perfectly but I can't get this one to compile.
public double getMean(int allGrades[][])
          int total = 0;
          for (int grade : allGrades)
          total += grade;
     System.out.println("Total is "+getMean(grades));
          return total/allGrades.length;

Which is better for music production: macbook air or pro?

Which is better for music production: macbook air or pro?

The MacBook Pro has higher specifications, depending
on the model, and then CTO additional upgrades.
The Air does not have a Retina display, but has lesser
specs, so that may make a difference. They still offer a
low-end MB/Pro w/ optical drive, w/o Retina; specs vary;
it may work in your instance. You'd have 14 days to take
a new Apple computer back, so keep that in mind.
Good luck!

You are certainly welcome to your opinion. I'll stick to my reply.
In view of the fact that there are numerous applications that run properly while creating a lot of internal heat in a MBP indicates that it does not follow that heat is an inhibiting factor (within designed parameters). Thus my comment is certainly not opion, rather fact. You certainly are entitled to your reply but a third party reader should be be apprised of what the facts are.

Which is better for physical therapy graduate student, a MacBook air or MacBook pro?

Which is better for a physical therapy graduate student, a MacBook air or MacBook pro?

Macbook Air
I cannot see you using strenuous applications to help you with a Physical Therapy Degree.
Have a think of whether you want an 11" or 13".
I'd recommend the 13" because although the 11" is perfect for taking notes in class etc.; when it comes to performing as a desktop and not sitting on your lap, it can seem too small.
The 13" is the best of both worlds. You can keep the portability and the power in one.
Make sure you get a large enough SSD, they always fill up fast with documents and possibly downloaded text books etc.
With the 13" if you decide to create a innovative project or a collection of photos, you can also use more RAM-consuming applications like iPhoto and iMovie, or even Aperture without worrying about freezing.

Cant install NI-IMAQ for USB Cameras

i tried to install NI-IMAQ for USB Cameras.but it cant get it to install its giving the error need higher version than 7.0 but i am using 8.0 .also it is saying that it needs vision 7.0 ........??wat are these error ..how can i get it install ????????help
thx
Regards

nolsqn,
Can you clarify what you have installed? You must have all of the following installed to get NI IMAQ for USB Cameras to install:
System Requirements:
- Windows 2000/XP (English,
Italian, Japanese, French, Italian, Norwegian, Dutch,
Spanish/Portuguese, Russian, and simple Chinese)
- LabVIEW 7.0 or higher with NI Vision 7.1 or higher for the USB LabVIEW support
- Vision Assistant 7.1 or higher for the USB Vision Assistant plugin module
- Vision Assistant 8.0 or higher for the USB Express VI
It sounds like you are missing Vision Development Module (this is what is referred to as NI Vision)? Is this true?
