Find a speed of objects using an array of position 1-D

Hi all

I'm taking a derivative of a table 1 d of points of an object that I followed so I can get his speed. Basically I have a table 1 d of the position (X, Y, Z) coordinates which are continuously updated (or updated) every 100ms. I want to transform the data from this position in speed data. Is the solution to this problem as easy as using the function derived from LabVIEW?

Thank you!

Perhaps.

I would certainly start. Or maybe just use shift registers and subtract to get the differences between X [i] and X [i-1].

You look at dx, dy, and dz separately or do you want derivative along certain vectors?

If your data are noisy, derivatives tend to increase the noise.  In this case, the algorithms of smoothing and derivatives of Savitsky-Golay may be advantageous.

  • Problem with AddEventListener to objects using forEach array

    I have a file with a many cases of button, whose name I put it in 2 different tables.  I add an eventListener to each button dynamically using the forEach... instructions in the method.  I want the buttons in the first table to call a function and buttons in the second table to call a different function.  I do some compile errors, but my problem is that the buttons in the two tables call the two functions.

    < code >

    var btnList:Array = [cultivated, bBlue, AOR, bPurple, bGreen];
    var greenList:Array is [gb1, GB2, gb3, gb4, gb5, gb6, gb7, gb8, gb9, gb10, gb11, gb12, gb13, gb14];.

    for each type (var btnList b) //data in table buttons
    {
    addEventListener (MouseEvent.MOUSE_DOWN, btnOverHandler);
    addEventListener (MouseEvent.MOUSE_OUT, btnOutHandler);
    }

    for each (var gb:String in greenList) //data in table type buttons
    {
    addEventListener (MouseEvent.MOUSE_OVER, overHandler);
    addEventListener (MouseEvent.MOUSE_OUT, outHandler);
    }

    function btnOverHandler(evt:MouseEvent):void
    {
    If (btnList.indexOf (evt.target.name) < 0) / / check if evt.target is object table
    {
    trace ("mouse button down");
    }
    }

    function overHandler(evt:MouseEvent):void
    {
    trace ("mouse button plot on");
    }

    < code >

    You're not add event for buttons listeners - you add just them, so any object on the stage can trigger them.  In addition, your greenList isn't a list of string values that you will encounter problems at least two places in your code.

  • Moving an object using the arrow keys

    I think I've changed the default distance to move an object using the arrow keys of 1 Point (1/72 inch). Can you help me change the default or tell me how to set the distance you can move an object such as a text field using the arrow keys. Thank you.

    It is based on your grid interval setting in the drawing AIDS palette. For a grid of 1 point, you would need apart 12/pc (although it says the points of the grid is picas, points 12-pica).

    I find 1 point too fine, I use a grid of 4/pc (3 points) and I have all my subject base around multiples of 3 measurements.

  • How to select cases or an event using an array of Boolean 2D.

    Hello world

    I'm trying to use an array of Boolean 2D to select different events or case. For example, if the variable Boolean 1 and 2 are TRUE, case 1 will be selected. If the Boolean variable 1 is FALSE and 2 is true, case 2 will be selected and so on. I tried to use the Boolean to the number, but I need a way to differentiate between B1 = B2 = FALSE and B1 = B2 = TRUE, FALSE, TRUE. In other words, no two Boolean combinations can lead to the same case, seminar.

    ~ Mario

    You need to remodel your table 2D to 1 d first.

    Now, assuming that you have the items in table 64 less thant, "boolean array to the number" will give you a unique number for each possible combination of bit.

    M_Mario_M wrote:

    I tried to use the Boolean to the number, but I need a way to differentiate between B1 = B2 = FALSE and B1 = B2 = TRUE, FALSE, TRUE.

    As mentioned, each combination will give you a different value. You must simply ensure that you Add unique cases for each number. Add as many cases you want to structure your business. If you do not, several models of trigger default case-sensitive.

    If your problems persist, please contact your code.

  • Find the base of Object.vi doesn't work is not in the picture 3D Solidworks Import control

    Hello

    I try to import the Solidworks model, I get the whole Assembly in 3D image image but when I try to find the particular help object to find object.vi It gives me

    Error 1 ganglion invoke in NI_3D photo Control.lvlib:Find Object.vi-> VRMLviewer.vi


    Possible reasons:
    LabVIEW: An input parameter is not valid. For example if the input is a path, the path can contain a character not allowed by the operating system such as? or @.
    =========================
    NOR-488: Command requires GPIB controller charge controller.

    Is there a specific way to be part of Solidworks or wjat could be the possible reason.

    Thanks in advance.

    Although you probably have names on your model, your VRML (.wrl) file does not work. If you try to open the file with a text editor, you can fix this by adding the following statement before processing:

    Basis of DEF transform {}

    This will allow you to access the location of the VI to find. The error is because LabVIEW has not found the name in your VRML.
