Where is the initial focus point in a stereo vision system?

Hello, everyone

I use the LabVIEW Vision stereo. After I calibrate my stereo vision system, I want to check the accuracy of my system. I can't depth of each point in my photo, but where is my axis point of the initial Z?

In the most recent NOR Vision Concepts allow, it is written that NI Vision makes 3D information with regard to the rectified left image as the new optical Center will be held at (0, 0, Z) position. Is the point the original Z axis on the CCD of the camera on the left or the optical centre of the lens of my camera left?

If anyone can help me?

Hello

I would say that the origin of the coordinate system is at the center of perspective, which is the center of the camera's projection.

So, Yes, the optical centre of the lens of the camera on the left. It seems more logical to me...

Best regards

K

  • Set initial focus point in the middle of several models, the flow of tasks and fragments.

    Hi guys,.

    With the help of JDev 11.1.1.4.

    I've got the fragments of the page for which I would like to set the initial focus. The problem is that, often, these pages of .jsff are nested in page templates, model train, dynamic regions, etc. AFAIK, the original goal of a component is on the document. The trick is to find what all the prefixes are before the .jsff component.
    pt1:dynamicRegion:3:pt1:t1:0:it1
    Y at - it an easy way to understand all of the prefixes before that: it1, which can often be radically different?

    The easiest way would be to set the initial focus to say "defaultFocus" and have each .jsff has a component id called "defaultFocus? Feels like cheating, but any other way I can think seems much too complicated.

    Thank you

  • The rebel sl1 is adjustable to use only the Center focus point?

    The rebel sl1 is adjustable to use only the Center focus point?

    I've never used one, but I'm sure you can.  Judging by the images I found on a Google search looking for the button in the top right rear, it looks like a rectangle with a sign in there.  Which will allow you to select your focus points.

  • Where is the initial output PID Terminal?

    Hi all

    I'm upgrading from the code from LabVIEW old something to LV8.6.1, which uses the PID Control Toolkit. I see that in .vi PID (table dbl), the initial outputs can be set using the outputs Intial input terminal. In the last toolkit PID, things were simplified and now there seems to be no way to adjust the outputs initials?

    It is important that I can do this, because the system will begin to control a platform that is already running. Initial results are set to the settings at the time of the takeover, and which ensures a smooth transition between user control and automatic control. But if I can't set out initial, I think that PID control code everything is set to zero at its first iteration. This could be catastrophic?

    If I do not take into account the results of the iteration, then let it take control of the second iteration from, is that going to help? Or will there be another (though less bumpy) switching between manual and automatic modes?

    All the most popular boards. Thank you

    The advanced PID VI (in the PID toolkit) has an option 'Manual' that allows to change smoothly from manual to automatic operation.

  • How to set the initial focus to the second field?

    Hello

    I created one for the user to enter data.
    The first field of the form has a default value.
    Therefore, when the screen is rendered, I would like to put the cursor in the second field for the user to enter data.

    How can I do this?

    Thank you

    Gabor

    Ahh and now for points...

    Set the display of Page attributes > focus cursor "do not carry the cursor".

    This allows your javascript to run.

  • How to show the ListField focus point in reverse or other color

    I saw similar comments, but not enough information to go. I'm new to b'berry and java too, this is my first application, and it comes to Notifications, storage options, the requests HTTP, XML and browser integration, there has been a steep learning curve!

    I have a ListField with a ListFieldCallback, which draws text in the list of members. When the wheel is used to select items, the background is blue but unchanged in the foreground, making almost unreadable text. I want the text to be reversed in color, or blue background (preferably) be a rectangle outline. I think that the answer lies somewhere like getCallback and focusRect, but I don't know what to do. Ideally, I would like to change the code in the callback class 'drawListRow()', but I suspect that things are not so simple!

    My code looks like (sorry I can't put much too, I wanted to know what pieces of change):

    Thanks Mark,

    I ended up using a similar method with a twist. I drew a background rectangle slightly smaller than the list item, then the blue selection box turns into a blue outline, and colors of foreground elements are not hidden by it:

    ...
            public void drawListRow(ListField list, Graphics g,
                                            int index, int y, int w) {  
    
                ListEntry _entry = (ListEntry)listElements.elementAt(index);
    
                //Draw background rectangle to replace dk blue selection rectangle with outline only
                g.setColor( Color.WHITESMOKE); //Pale but not white
                int h = list.getRowHeight();
                g.fillRect( 2, y+2, w-4, h-4);

    STOP: 0XC000021A

    Can be a difficult problem to solve, and you indeed need a technical help in a real store of the computer
    (not the leeks and the glances at a BestBuy or other BigBox stores) or system manufacturer support.

    Cause

    This error occurs when a subsystem of mode user, such as WinLogon or the Client Server Run-Time Subsystem (CSRSS), irremediably compromised and security can not be guaranteed. In response, the operating system goes into kernel mode. Microsoft Windows cannot run without WinLogon or CSRSS. Therefore, it is one of the rare cases where the failure of a user mode service can stop the system.

    Incompatible system files can also cause this error. This can happen if you restored your hard disk from a backup. Some backup programs may skip restoring system files which they determine are in use.


    Solve the problem

    Run the kernel debugger is not useful in this situation because the error occurred in a user mode process.

    Resolve an error in the user-mode device driver or system, third-party application service: Because the bug 0xC000021A control occurs in a user mode process, the most common culprits are third-party applications. If the error occurred after the installation of the new or updated device driver or service system, third-party applications, the new software should be removed or disabled. Contact the manufacturer of the software on a possible update.

    If the error occurs during the system startup, restart your computer, and then press F8 to character-based menu that displays the choice of operating system. In the Windows Advanced Options menu that results, select the last known good Configuration option. This option is most effective when a pilot or a service is added at a time. If the error is not resolved, try to manually remove the offending software. If the system partition is formatted with the (FAT) file allocation table, use a MS-DOS boot disk to access the hard disk of the computer. If the system partition is formatted with the NTFS file system, you may be able to use Safe Mode to rename or remove the defective software. If the defective software is used as part of the start-up procedure of the system Safe Mode, you must start the computer by using the Recovery Console to access the file. If a room newly installed if material is suspected, remove it to see if that fixes the problem.

    Try running the emergency recovery disk (ERD) and allow the system to repair any errors that it detects.

    Solve a problem of file system do not match: If you have recently restored your hard disk from a backup, check if there is an updated version of the backup/restore program available from the manufacturer. Make sure that the latest Windows Service Pack is installed.

    I understand that the definition of the destination of a bookmark also sets the magnification of the view. Apparently, it's always the case, and that doesn't seem right to me.

    Suppose that all I want is for each bookmark to take the reader to a particular page, and I don't want the expansion of any different view of enlargement that the player is currently using. For example, I set the initial view, magnification by default when you create the PDF file. How can ensure me that the reader will not deal with a different point of view magnification when you click on a bookmark and be redirected to the page?

    Select the existing action "go to a page in this document", as you did in the 3rd and 4th example you view and click the button change, and you should see where you can select "Inherit Zoom" for the zoom setting.

    Edit: I see that you found.

  • Customization of file exchange: what is the initial and maximum size recommended?

    Hi everyone and hurt.


    After response of harm to my question on how to install diskettes, evil said:


    "allocation of disk: is a three step process, first of all, you set the boot order in the BIOS, then you format the windows disks and assign drive letters, then again Windows you set up for the swap file." Then the allocation of media preview cache, project etc. is made in preferences, and setting up a PR project."


    and I have a question about the pagefile.


    First of all, let me tell you describe my new machine, there a configuration to 4 disks, no RAID, 16 GB RAM, with OCZ Vertex3 for programs and the OS, which I installed Windows 7 Ultimate 64 bit on this disc, Web Premium CS5, and Acrobat 9 Pro. In the BIOS, I did drive OCZ (OS), be the priority in the boot order.

    Later, after checking the system is functioning, I'll upgrade to Classic Collection CS5.5, so at this point, I named my 3 expansion packs to this title.


    WDC WD 2002FAEX-007BA0 - "Media Projects (D).
    WDC WD 1002FAEX-00Y9A0 - "Swap file, media Cache (E)"
    WDC WD 1002FAEX-00Y9A0 - 'previews, Exports (F).

    Then, because now they are simply names I gave on different drives, and I'm trying to change the paging file, switching happens in the disc of the operating system, in order to arrive in the disk that will be designated for media Cache (by the Prime Minister, subsequently).

    Thus, in the performance of Windows Options pane, I went to the Advanced tab, and under virtual memory, I hit 'change', uncheck automatically manage file size exchange for all readers, select drive E, which is the drive that is having the pagefile to happen there.

    And the question, assuming that I'm supposed to select custom, size can harm you, or / and others, please recommend the initial and maximum size?

    Alternatively, I have to select "system managed size"?

    Thanks :)

    Minimum,.

    Where you put the pagefile just does that much of difference, when you have 16 GB (as you do) and 24 GB still less so (as the user in the other thread).

    If I had your material, I put on E: and make static at 16 GB min and max 16GB (bad suggests same size).

    I don't spend more time reading or to dwell on "static pagefile" However unless you want to purely for fun.

    When you have enough RAM that your applications require no more you have, Windows must either ask for a large part of this file. Ten years when the RAM chips were much smaller and the cost per GB was more expensive that now, details of page file were indeed more important than they are today.

  • Where is the messages the button 'send '?

    I see a button a blue circle with an arrow pointing up. I'm guessing that this button brings me to the top of the conversation. It is where the word 'send' used to be. So, where is the button 'send '?

    This arrow is the new Send button. In addition, if you hold down this key before sending a message (or 3D touch if you have a 6 or higher), you can change the appearance of your message, or you can add things to the screen with this message. I hope this has been helpful!
