Help with the help of the LearnCalibration.vi

I have a set of points which are the coordinates of the points that they were projected on a screen.

I have another set of points, i.e. the coordinates of the points that they were seen by a camera.

I would use the LearnCalibration.vi to understand the scale, rotation, and translation between the two sets of points.

When I put the reference points (315 rank, pairs of coordinates pass from x =-700 x = + 700 and the values y corresponding) and points to the real world (315 row, the pairs of coordinates pass from form x =-900 x = + 900 with values y corresponding) in the LearnCalibration.vi, I get an error too small of the image.  The reference to the image entry is a comma floating image in grayscale.

All thoughts.

Hey Hummer1,

2 things: first of all, your input image must be a U8 or an I16, but is not causing your problem.

We do not have great documentation on this including VI, then I need to examine it further. While the information says that an image is no longer necessary for the calibration of your program, it IS necessary to have a picture to add calibration information to. As you have probably noticed, this particular VI is not an output that allows to adjust the image, it added the calibration information to the image so that you can calibrate in screws later.

You want to wire your image format the camera at the entrance of the calibration learn VI, so that you can then use the calibrated image VI.

It took me some time to make it work as I had hoped, but this should solve your problem.

Thanks for your patience!

  • With the help of Club running on the Nike watch +.

    Hello

    This is something I have tried to work for a while and have not yet been able to find an answer. At the moment I use Nike + management club on my iPhone to follow the tracks that I find that gps is better than just using the application of the workout on my watch. However, something that really bothers me is that I start the race on my phone, but I can't then view my stats while running without having to press on and tap the watch and wait for the application to load, very irritating to race. I want to be able to lift my wrist and live stats are there to watch me, not listening and not get my phone out of my pocket. Surely this is something that can make the original watch?

    As a separate issue with the new app, Nike +, it does not recognize the songs I downloaded on my phone of Apple music in my playlists, then I have to play the separatelay of music through the application of music as opposed to go with Nike +? The ides on how to fix or is this a known problem with the latest Nike + app?

    Hello

    You may find it useful to consult the support resources of Nike and/or contact Nike for assistance with the help of their application:

  • With the help of old gear series noon on El Capitan

    I have a Vox Tonelab SE effects audio Board (around 2004), there the old serial midi on the back ports. I hung with the help of a USB MIDI interface cable. While the USB Midi interface to the show in Audio / Midi set upward and also in the profile system for USB port it does not detect the Vox Tonelab so no communication lunch.

    There is a POWERPC application called ToneLabSE SoundEditor which I downloaded and installed in the hope he would install a driver but I guess that this obviously doesn't work on INTEL in any case. Using Wine I can run the PC version, but still no communication via midi.

    Someone at - it ideas, would like to get this Panel communicating effects via MIDI.

    Thank you

    Solved! Using the WINE app I've run the version of the PC of ToneLab SE editor application. So pretty unintuitively by changing the serial midi to USB, SERIAL interface cables that went to the and out on the Tonelab SE. Now of the Se ToneLab editor I can write banks of programs to hardware Tonelab, but unable to empty the banks since the material Tonelab to software. My main desire was to use Expression pedals on the Tonelab as Midi Ableton controllers and some of the switches to the control of the Looper stomp. Now I can do it all. Hooray!

    Why did you start a new post? Post again only after only 8 minutes accomplished nothing.

    There is no general problem going to EL Capitan on your Mac.

    Some applications may require updating.

    Some devices like printer may require the updated drivers. For some readers of devices not being updated are available.

  • With the help of pictures with iCloud

    I have a problem with the use of the photos and iCloud which I can't solve alone...

    I love the feature that when I snap a photo on my iPhone, it shows up on my other devices as well. However, it is much, results use all my ability to iPhones. I want to be able to remove the 'local' storage of the photo in my iPhone, but still be able to view in my iPhone. How do I do that? After all, isn't that what iCloud's all about?

    ICloud-storage is full, I want to remove too much iCloud and keep only locally on my MacBook for display. How remove the photo from iCloud, but always keep locally on my Mac? And if I don't want to use photos as my photo Manager, how do I take their 'out' photos and store them in the form of directive on my Mac?

    I'm afraid that if I simply enter the photos app on any of my devices and try to remove a photo from iCloud, remove them permanently. How to avoid this?

    I hope someone can help me with this problem!

    With iCloud library enabled, you cannot delete a photo on a device (or iCloud.com) without deleting each device which uses iCloud photo library (iCloud.com). In order to save space on your mobile devices (and indeed your Mac if you want to) turn on the optimization of the pictures on these devices (settings > photos & camera > optimize storage on your mobile device and Photo preferences > optimize storage on your Mac)

    Dynamic optimization, it reduces the resolution of your photos, if necessary, so that you don't notice it occurring initially. However, when necessary, it is very effective, and users have reported libraries being optimized for much less than 10% of their original size in some cases. My own library is about 9% of its original on my phone size.

  • I just got a new modem (Arris SB6190) and now my Airport Extreme does not connect.  It worked fine with the previous modem (a rented one TWC).  Help!

    I just got a new modem (Arris SB6190) and now my Airport Extreme does not connect.  It worked fine with the previous modem (a rented one TWC).  Help!

    Always recommended to reset the airport back to settings by default and then set up again whenever you have a new modem or change your Internet Service provider.

    Turn off the new modem for at least 30 minutes. More is better.

    Perform a hard reset on the AirPort Extreme, then it turned off.

    Make sure that the Ethernet cable connects the modem to the "O" on the AirPort Extreme WAN port

    After the power of the modem 30 minutes down, turn on the modem and let it run for at least 5 minutes by itself.

    Then, turn on the airport and let it run a few minutes

    Set up AirPort Extreme again

    Important note... There are many reports of problems with the modem Arris SB and airports. Both are great products, but they do seem to work perfectly together for some users.

  • When I click on the Firefox Start Page it goes to a full screen with the logo of Firefox... full page... nothing else showing... Help, please.

    Something went wrong when I was trying to figure out how to get my regular size rather than the full screen display. Cannot get any tools, options, etc. Only the logo of Firefox with the search bar... That's happened.?

    Normally the F11 key will pass you to the normal display mode (or in the display full-screen function of the current screen). Does it work?

    Mode full screen, drag your mouse point to the top must cause the toolbar area to slide down. Does it work?

    If Firefox is 'stuck' in the view full screen, the file that contains the dimensions of the window may become corrupted. You can rename the file to fix this problem, but it may also affect what bars are displayed (for example, if you are using the classic menu bar, you may need to which restart). Here's how:

    Open the settings folder (AKA Firefox profile) current Firefox help

    • button "3-bar" menu > "?" button > troubleshooting information
    • (menu bar) Help > troubleshooting information
    • type or paste everything: in the address bar and press Enter

    To open the page without having access to all the foregoing, either:

    • Hold down the ALT key and press H to activate the Help menu, release the ALT key and press T to display the troubleshooting information page
    • type or paste the following text in the search box of the start menu, and press ENTER:
      firefox.exe "about:support"

    In the first table of the page, click on the view file"" button. This should launch a new window that lists the various files and folders in Windows Explorer.

    Leave this window open, switch back to Firefox and output, either:

    • "3-bar" menu button > button "power".
    • (menu bar) File > Exit

    To exit Firefox do not have access to the foregoing:

    • Hold down the ALT key and press F to activate the menu file, release the ALT key and press x to trigger an exit

    Pause while Firefox finishing its cleanup, then rename xulstore.json to something like xulstore.old. If you see a file named localstore.rdf, rename this to localstore.old.

    Launch Firefox back up again. Windows normally appear again?

    I can't find the right part of the forum to ask questions about the forum itself and its features. I wonder what the right place and the way is to get help with the forum system itself. I can find the place to ask questions about specific Mozilla products very well.

    Only if he had problems with the update download which is unlikely. You would have to do a restore of the system, not only a reset.

    Opening was a pro the Pro amateur-oriented or serious app, usually shooting Raw, probably on a digital SLR.

    If that's you then pictures will miss a lot for you.

    If this isn't the case, then opening was probably overkill for your needs.

  • Cannot reset Apple ID same security issues with the link for valid reset. Help?

    So, I'm trying to reset my security questions, because I forgot the answers. I followed all the procedures to do, but it won't work.

    I clicked on the link for reset enter my Apple ID account page, then get the message: 'Reset Instructions sent. An email with the instructions was sent to @emailaddress. Follow the instructions in the email to reset your security questions. » - OK

    I opened the email: "Dear ME, recently made you a request to reset your Apple ID security questions and answers. To complete the process, click on the link below. Reset now >"I click on the link, it opens a new window with a login screen. - OK

    On the login screen, I entered my account information, email, and password in the fields and click the button to continue. Instead of connect, I get the message pop-under from the password field as follows: - FAIL

    I try again and again, but it never works. Whenever I get my password and trying to proceed, the loading spinner runs for a bit, then I get this message "to reset your security questions, sign in to your account and start again." I have never spent this page and in a region where I am able to actually reset my security questions. I tried with all browsers, Firefox, Chrome, Safari... nothing works. Now, I have tried 3 times reset by e-mail. It will not work. What is going on? Is the site broken?

    To make things worse, I don't have an option to call for framing according to the Apple website. The only option I get is to contact my operator. What the * is my carrier will repair my Apple ID? It's very frustrating say the least. Someone please help!

    You cannot reset the Security Questions If you forgot the. You can only reset them if you know them (which means that you also know your password).
