Trace the outline of the acquisition of the live camera: best strategy?

Hello world

I am creating a VI in order to acquire images from a camera (Basler scout). Among the features, I need to implement, one is the direct route to the contour of the gray scale values to increase their visibility (I then use it to tune in to a light source a Gaussian distribution centered).

My problem here is that the images are too big and the whole VI accused, with a new track that appear every 3 to 5 seconds, which is too long. A constraint is that I must be able to record images with full resolution.

Attached are 2 easy examples, one using labview only and the other using Matlab to decimate the number of pixels and a typical result. The two performed in the same way, too slowly.

Ultimately, conversion and decimation in matlab seems very time consuming too. I'm not a labview expert so I can have overlooked an easier way of doing it, but so far I feel really stuck...

So should what direction I follow? MATLAB or Labview? What could I use in Labview to reduce processing time?

Hope you can help me,

Best regards

Hi again,

I found that by using a 2d graphic intensity is partially satisfy my needs, but I'm still interested to have a solution for a 3D terrain!

Best,

  • How to trace the greatness of the variables compared to the timestamp with evenly spaced samples in time?

    Hello world. I need to trace the variable amplitudes compared to the timestamp (date and time), but the time intervals between samples are not equidistant. In my area, this is called trend plot. I'm surprised that Labview does not a vi to do this. The only solution that I found so far is to save the data in an Excel file and open this chart in Excel because it has the ability to trace what that this is against what whatsoever is not limited to something as even spaced samples. How to achieve this is Labview? A graph of waveform vi would be perfect if it was not by the fact that it works with even spaced samples.

    Thank you.

    Paulo Siqueira

    Your requirement is directly possible with LabVIEW.

    You can spend time to understand the difference between 'Chart', 'Graph' and "Graph XY".

    VI attached is drawing samples of unequal time.

    Hint:-right click on the 'XY' graph-> properties-> display-> 'Axis of X' = absolute time Format

  • How to trace the signal acquired against the clock all the time fixed by using Graph XY?

    Hello

    My goal is to trace the signal acquired against the clock all the fixed time dynamically. In General, it is like trace the waveform of the signal against the clock in a graph, but don't keep the recent 10 min waveform. My current approach is to get the timestamp by a VI and the express VI to use XY graph to make the plot. The result keep all data in the history which is not what I want. My question is that how to achieve my goal?

    Thank you very much

    Hao

    One way to show the last ten minutes of data is to use a graphic instead of a graph. Set the size of the history of the ranking for the number of samples you acquire in ten minutes.

    If you want to use the graph XY, you will need to manipulate the data yourself. If you don't want data from the last ten minutes and you want to throw all the old data, set up a circular buffer sized to hold the ten minutes of data. Once the buffer is full (after the initial ten minute break) adding a data point removes the oldest point. Make the buffer of a 2D with X data table in a line and the data Y in the next line. A queue with loss can be used in recent versions of LV to implement a circular buffer. In older versions, a driving force would be a good choice.

  • How can I trace the IP address of the machine source "remote shutdown"?

    Hello

    I have Activate Shutdown event log in my XP machine, however again, I'm not able to trace the IP on 15 XP workgroup computer that stop away from my machine.

    Is the command that could have been used: stop, f, r, m- t: 0

    Can anyone suggest me how to trace this IP of the remote machine?

    Or at least tell me what protocol or port shutdown.exe uses when it sends the command remotely.

    I captured ProcMon, Journal NetMon and wire-shark, yet, I have no idea to start my investigation.

    Help, please.

    Nothing of what you said is causing me to believe that a remote machine is responsible for - or - nothing to either exclude it.

    Recommend that you disable the administrator account to see if the actions continue or don't use is no secpol.msc:

    Local policies | Security options | Accounts: Administrator account status

    .. .set to disabled.

    You are welcome.

    You can also rename the account using accounts: Rename administrator account

    ----------------------

    In addition, you can go to local policies | The audit policy | Audit system events

    and the two checkboxes for the success and failure

    In this way, newspapers will be created with details about what you can see in the case where the Viewer. The Windows logs. Security

    ------------------------

    In addition, if you check on the user rights assignment section, it is useful as things "Force shutdown from a remote system" - you can remove administrators from there.

  • How to fill the open paths to Trace the Image (automatically)?

    I drew this picture with a pencil and parsed it as a png image:

    [Dragon.png]Dragon.png

    I want to have closed roads, so that I may fulfill different

    areas with different colors easily with the live paint bucket

    (for example blue eyes, the rest in brown color).

    I've vectorized it my png Image trace (trace first, and then expand the button).

    You can see the settings I used to trace right picture of the image.

    AfterExpand.PNG

    [AfterExpand.png]

    1)

    These settings are good to vectorize a pencil drawing or

    are there settings better?

    2)

    I think that the blue lines are the paths.

    Is there a possibility to mix and to?

    3)

    You can see there are open paths where they need to be closed:

    Open_Paths.PNG

    [Open_Paths.png]

    Is it possible to close automatically with

    a function of artificial intelligence in Illustrator with fitting curved paths?

    How can it be done?

    4)

    If 3) is not possible, what is the best practice to do it manually?

    You can see that the shilouette has a large diameter, so I can not only

    create new ways of binding because they have zero diameter.

    5)

    First I drew the image with a pencil,

    So it was not possible to have all the lines of equal diameter.

    But that's what I want.

    Even there is a possibilitiy to set all the paths of a vector image

    to a certain diameter in one click?

    (1) totally depends on your drawing. Try to find the best for you.

    (2) view > hide edges

    (3) the live paint function has a detection of space you see in the menu object

    (5) you would nee to draw it differently: create: features

    But for this simple drawing: just it draw manually.

  • I have the creative cloud and want to know if there is an app or a program that I can buy in order to trace the pictures I want photoshop?

    I have the creative cloud and want to know if there is an app or a program that I can buy in order to trace the pictures I want photoshop?  I want to store photos on a peak and then put them on a table shave so I can use them elsewhere. For example, I take a picture of our equipment in the factory and want to buy items on the bottom and wear the equipment to a white background to post on my site.  Using a mouse to draw the image is inefficient and inaccurate.  A pen in my hand is much better.  Ideas?

    Thank you

    There are many Photoshop tutorials on it online. You can refer to them, or you can search the Internet for more information.

    If you have a pen and Tablet compatible with Photoshop, you can use that in addition to or instead of a mouse.

  • How to trace the path of a motion tween?

    Is it possible to trace the path takes a symbol and create a (or the forms that appear as a tracing)?

    Example very Simple: the letter C, without serifs.  Basically a bow.

    I would like to than the C to 'pull' in the animation.  I just hope interpolation along the C of movement and trace its path. I did a shape tween and wasn't happy with the results.  In addition, complex paths would be very difficult to shape tween.

    Thank you!

    This is best done with ease using Adobe After Effects using an edge effect and animation which.  You can then import the output MOV in Flash Pro for the purpose of interactivity.  Otherwise it would be better done by drawing manually track with the mouse or tablet in Flash directly, rather than a script, even if you can exist if anyone knows.

  • Trace the path with the brush of the Interior

    Hey everybody!

    I'm trying to stir up a path between the panels 'WAYS', but I want to caress the inside of the track.

    now he is gone from the center of the lane.

    I don't see an option to mark Center/inside/outside similar in artificial intelligence.

    So, how PS decide trace the path of the Center? y at - it an option to change this?

    http://i.imgur.com/6dVsd.jpg

    Rather than make a path of the text, you can make a path to the center of the letters, load a selection of the text layer and then stroking the path.

  • Connection of the USB camera - OR-IMAQ for USB cameras installation problems

    I tried to install the usb http://zone.ni.com/devzone/cda/epd/p/id/5030 camera application

    Unfortunately it does not work. I don't know the usb icons in my function palette. can you help me please?

    I want to only connect a camera usb with labview. How can it be difficult. any help would be appreciated.

    see you soon

    Hello

    You first need to make sure that the USB camera is DirectShow compatible.  If it is not it will not work with the software of our vision. You must use the drivers IMAQdx (which requires a license) to acquire from a USB webcam.  Once you have installed the drivers IMAQdx (Vision Acquisition Software) and drivers that come with the webcam is installed, you should be able to see it able & Automation Explorer (MAX).  Once you can see it in MAX you can use it like any other device in LabVIEW.

    You can not. However, I'm not sure why you think it's a privacy or security threat. The only thing that can be accessed without unlocking the phone is the camera to take pictures. No one can access your data already on the phone.
