• Subtract the model image of a real-time video and image/video subtracted from output

  Hi all

  I have a case in which I need to acuiqre a video (of circular loop) to a camera (which I am able to do with the vision development module in avi format) and subtract the model standard (for loop) image of him and display the output for each frame subtraction. The subtraction will tell me how much movement there was in the loop in real time. Is it possible to do?

  I donot want to save any image or video, just want to show the subtraction of real time to the user

  Joined the image.not still able to add video

  Hello AnkitG,

  Subtract the IMAQ VI removes one image from another or a constant. You can then view the removal from the user or save the images if necessary. Here a link to the reference IMAQ subtract VI.

• How can I make a person in a gesture of real time video as the background moves more quickly?

  So the plan is to make a video that has only one in midle or at a specific position in the video in real time and things or people that surround this person to spend x times faster without coverage or ruin the video by spanning the main character. I've seen a few videos with this in my mind, I think that this is done by placing early in the video, the main character in a place that no one intervenes so that it can be done with diapers multiples and mocha. Is it like that? I would really appreciate the help on this.

  Thank you!

• How to combine real-time video with LabVIEW indicators so that the video can be displayed and saved with the overlay data

  Let's assume for the moment that I can find a device for which LabVIEW has the appropriate drivers.  Is it possible to combine the camera feed with digital indicator fields so that there is a video out showing the data superimposed on the live image?

  I'm talking about something like a screen of the camera where you see the camera settings are displayed on the image in the viewfinder.  Note I have one isn't about analysis of video data or somehow reading parameters of the camera to the camera.  Data would be temperatures, pressures, speeds, etc., acquired by different instruments at the same time the video is captured and processed somehow by LabVIEW.

  No problem Wildcatherder, don't let me give you an overview of the process.

  When you get a video acquisition method entry, it will be an image format. Essentially, it's a bunch of images that are updated at the speed of video capture, just like the material. There are screws express (wizard - like elements) that simplify the obtaining of images from your video source. With the drivers and measurement and Automation Explorer installed, you should be able to get at least the image.

  If you have IMAQ toolkit, I mentioned, you could just wire the reference image (a purple wire wavy) and a text input (say, a temperature that is converted to a string) in the text overlay VI and it would produce the desired effect. Without this, you will need to convert the Image into image (these are two different data types in LabVIEW) and use the image instead, editing tools (essentially replacing pixels in 2D image data). You would then update an indicator of the photo with your photo altered, if all goes well to the pace of the acquisition hardware. As I said this is less elegant and can take a certain amount of time processor. If you view these images at all and are just their routing, it should be slightly faster.

  I don't know about video production equipment, I mainly used entry Firewire or USB, the computer screen or the file data. However, if the driver exists, it should be possible, but a quick review of the functions doesn't seem to come with output functions. Cannot advise on hardware, but you can start with:http://sine.ni.com/np/app/main/p/bot/no/ap/vision/lang/en/pg/2/sn/n17:vision, n21:11600 /?

• Mark an object in real time on a displayed video acquired of a USB camera

  Hello

  I'm a beginner LabView user company acquired a project in which I need to see the video from a USB camera in LabView on computer screen. In the video, there will be a piece of metal, which is always a fixed position at the bottom left of the view. I need to mark a sign like arrow on the metal part, please take a look at the attached picture. In order to recognize the easier metal part in the photo, I drew a line of blue on the edge of the part, while the arrow was green. The arrow must point radially towards the center of the blue line (but the blue line may not need to be created) and must be there whenever I start the VI, throughout the video.

  How to view the video? Is it possible to create the arrow in LabView (either programmatically or manually mapping arrow)? If it is impossible to make the arrow, is it possible to simply mark a cross in the center of the blue line? The blue line doesn't have to be on the video.

  I have 2010 LabView with Vision Development Module. My camera are in the outlying NI-IMAQdx able and Automation Explorer section.

  Thank you

  My daughter has an air of ipad and iphone 6 mounted on a tripod. She would like to use his phone to photograph/video while you watch on his ipad (in real time)... is it possible? If so, what adapters or cables are needed?

  Hello!

  Unfortunately, this feature is only available with the GoPro cameras.

  And Yes, if all cables already existing for these purposes, it would be kind of a pain to take pictures and do not shake the camera accidentally. Maybe, VSCO camera makers will make such feature in some time in the future. This idea is excellent and innovative. Maybe even Apple will listen to users and make their new iOS 10.

• MAX cannot find two usb cameras at the same time

  Hello

  I want to use two cameras usb (Thorlabs DCC 1545 M) in NOR-IMAQdx in Labview, but it cannot find a single camera (the one plugged earlier), and also a single camera is shown in MAX. Both cameras working in the manufacturer's software, and if I unplug the 1 unit, the 2nd will be displayed in MAX after a refresh.

  I found that one camera is supported for each USB hub in Labview, and all USB ports in this computer correspond to a same hub online. I don't know if this is causing the problem.

  In fact, I need to take the picture in both cameras at the same time, a switch programmed between the two cameras will work for me.

  Any suggestion and comment will be appreciated.

  Hello Hosni,

  According to this link, you can acquire from multiple USB cameras simultaneously.  The limitation is on the manufacturer and how they interface with the bus of DirectShow.  When you use two cameras of the same make and model, it sometimes happens that not enough information is not IMAQdx to distinguish between the two cameras.  When you switch to MAX cameras, they come as different cameras, or they appear actually virtually the same?

  Since you said switching between them might work, I found an example that does just that.  Just make sure you give a name to each camera single camera.  I hope this will be useful for you.

  In addition, there is a bit of discussion on this topic on the forum of discussion already.  Check out these related threads, or use the search box to search for more.  There is much information available!

• Video output for PXI embedded real-time?

  I plan to buy a controller PXI real-time Embedded for security monitoring.

  Is it possible to use the video output of a controller PXI running RTOS to display a LabVIEW RT application messages? According to the literature, it seems that the use of the video output is more possible for Controllers PXI running Windows XP.

  Is there a specific application with LabVIEW RT?

  Thanx.

  H.L.

  Well, it works using the IMAQ RT video Out VI: images are displayed properly via the video output of the RTOS PXI controller running.

  Thanx.

• THUMBNAILS VIDEO DISAPPEARED AFTER THE INSTALLATION OF REAL TIME

  After you have installed the latest version of "Real Time Player" which is an upgrade to 'Real Player of cloud', all the video thumbnails are not visible on a single computer. 'Real time' has been installed on two computers with almost identical Windows 7 Home Premium and processors within minutes of each other.  A computer kept all video thumbnails while the other did not. So far I have uninstalled and reinstalled in real time, uninstalled and reinstalled Real Cloud, but still no thumbnail previews. I also tried the verification of the method 'display only the photos '.  I'm looking for someone who's hands are successful on empirical knowledge for this question. Thank you.

  Stanley,

  Here's a recent update on my original investigation.

  After an upgrade of RealTimes Player RealPlayer Cloud download failed to produce thousands of miniature video generated by RealPlayer cloud, I immediately started looking for answers in this forum of Microsoft.

  I have two new computers HP here on my desk. A computer has received the RealTimes Player download and continued to display thumbnails. This is the second HP computer that the thumbnails are not visible.

  Several answers to this problem repeated the same methods. I tried these methods more than once and still no pictures. Then I took action on your message and another someone from Real.com contact Real.com. The only way to contact Real.com was by email on their website. I sent them an email describing the problem. Now, it's my experience that Real.com has even good tech support for free download of RealPlayer. Their first suggestions were identical to the information I received Microsoft community. Following is a concise list of end to end on how I solved the problem before Real.com phoned for help, which may have included access remotely:

  (1) download the RealTimes Player "new" (that's their latest version of RealPlayer cloud;) I know now I should have stayed with cloud of RealPlayer).

  (2) a computer downloaded without any problems, while the second computer lost all thumbnails.

  (3) I contact Microsoft Community to get answers.

  (4) community Microsoft sends answers, including and meet someone from Real.com.

  (5) none of the above gives a solution.

  (6) I am Real.com e-mail for a few days through their website with no solutions.

  (7) I have uninstall RealTimes Player on both computers.

  (7) I call the HP Technical Support to make a 'system restore' on computers.

  (8) after the "System Restore", I reinstall MSE, and all thumbnails are restored on the computer and three external hard drives. All thumbnails are Windows Media files. None of the hundreds of RealPlayer Cloud files can be opened.

  (9) Real.com offers to call me at one time that I choose, which may include remote access to my computer.

  (10) I answer Real.com Friday that a time to call will be the following Monday.

  (11) the following Monday at the appointed hour, Real.com has not called. I waited 30-40 minutes. While I was waiting, I've been on the Real.com site read comments in the section "RealPlayer/RealPlayerCloud. In a response from Real.com Tech to one of the speakers, they gave to this speaker a link to download RealPlayer Cloud. I took a chance with this link and downloaded RealPlayer Cloud in my computer, not only did the Windows Media thumbnails remain, but I was able to play all audio Real Player and video files, and the "Download this video" button a drop down of RealPlayer has been restored. I turned so my attention on the other computer, clicked on a download link that says Cloud RealPlayer on Real.com Web site, and when the download is complete, it was the new RealTimes Player again, not RealPlayer Cloud. But, all right. All thumbnails are back in this computer while being able to play all Real Player files. Now, a computer has the 'new' RealTimes Player and the other has the original cloud of RealPlayer.

  (12) after all this was over, and two computers were back to normal, the representative of Real.com called (almost two hours late; he was on another call that lasted longer than normal). I explained that while you wait for him to call, I reinstalled Real Player on both computers and everything was back to normal. I mentioned reinstalling RealPlayer cloud on the other computer and it recommended that all was well under way, for whatever. I agree with you.

  (13) since the call of the representative, Real.com has sent me a couple of times and told me they were happy that the problem has been resolved and do not hesitate to contact them for any future problems. I asked for a download link for RealPlayer cloud which they sent a warning that they were not certain if the link has an expiration date, but to contact them for any problems or questions.

  (14) although I have Google Chrome on a single computer, all my audio/video download through RealPlayer Cloud/RealTimes drive is via Internet Explorer, not Google Chrome. I prefer the drop-down menu "Download this video" button at the edge of the screen in Internet Archive rather than the barely visible button at the top to the center of the page in Google Chrome.

  Microsoft 15 community) thanks and Real.com.

  (16) a lesson learned. When everything works fine, why switch?

• Problem using USB-6356 on target in real time

  I try to use the NI USB-6356 on a SBC I converted to a target for LabVIEW RT. I created a LabVIEW RT project with the Architecture of Communication continuous model. However, when I select target RT > New > NOR-DAQmx channel, the wizard says "no device found support.

  Here's what I've done so far:

  1. Installed Support in real time on the host computer.
  2. Installed OR-DAQmx 15.5.1 on RT target (it is visible when I develop the 'software' under the lens of RT in MAX). See Fig1.png and Fig2.png.
  3. Verified that the NI USB-6356 appears in max under target RT > devices and Interfaces. See Fig3.png.

  Even if the NI USB-6356 appears in MAX, it seems suspicious that it appears as a USB device generic (like the keyboard and mouse that are connected to the target RT). Maybe it appears that way because it is connected to a goal of RT, but it seems that it is not recognized as a DAQmx device. I don't know how get the target RT to recognize as a device DAQmx, given that the appropriate drivers, etc are installed on the computer host and target RT.

  Thanks in advance for any help!

  Sorry to be the bearer of bad news, but the devices USB DAQ (other than the USB cDAQs) are not supported on PharLap targets at the moment. The documentation could certainly be clearer, so I'll update soon to reduce the confusion on this topic.  This white paper, last updated in 2014 is clearer than we currently have.  It is also explained in this KBQ5, but the wording is certainly a little bit clear here.

  I'm not sure of any other solution that exchanging your 6356 for cDAQ USB system, or the displacement of a BONE no - RT.
