How to set the return on investment

I installed 'just' mink toolkit in LV2011 to get the digits on LCD display information.

As a starting point, I opened "Example LCD" and change.

However, KING seems to be an important concept in the vision.

KING should be measured from the top-fall position?

However, can you tell me how I can check KING in the picture.

Included is the example of the superposition of the KING on the ougghta.

I wanted to put the part or the entire region as the return on initial investment then attempted to verify if the 'get LCD ROI.vi' works correctly.

but he could not view the return on initial investment on the image.

How can I fill the KING descriptor to define a region on the image?

labmaster.

Question *) additional: using a code example, I found return on initial investment must be properly defined to identify the numbers.

Can you tell me the following...?

(1) rule to define the ROI on an image for good recognition of numbers. (for example, numbers only area...)

(2) can I do the code to find the original KING (connected to the well of recognition) automatically?

Changed the idea of rock.

Don't try with 7digit LED functions... Can be applied to a very limited image.

  • How to set a return on investment by program from four points

    Hello

    I'm working on a program that detects four edges and located at the four corners of the intersection of these lines.  I want to set a return on investment of these four points, but I'm having a hard time finding the right tool.  When I use the rectangle tool KING (polygon), lines don't end up matching the edges because simply from the top left and lower right corners as well as a rotation, and when he turns, the KING turns off the corners that I entered.  How to create a return on investment simply based on four corners?  It seems like it should be a very simple task, but I can't understand it.

  • How to set the timeout of read when using channelReader.ReadWaveform?

    I'm using a USB-6210/a. data acquisition, and it works fine until I have to take a longer than 10 s waveform.

    When I take a longer than wave form, I get the error 200284, "some or all of the requested samples are not yet acquired.  To wait for the samples become available use longer read timeout... »

  • How to set the 1st online number = 10 and increment 10 whenever you press the button to add a new line. Also enable users to enter the generic numbers, IE 13 and still increment of 10 23 or whatever.

    How to set the 1st online number = 10 and increment 10 whenever you press the button to add a new line. Also enable users to enter the generic numbers, IE 13 and still increment of 10 23 or whatever.

    I already have my chart updated in place with a button that will add new lines when pressed.

    Now, I want to clarify that the 1st row is 10 and all the other rows after this increase by 10. It will also allow users to enter any number they want, and the next line will increment of 10.

    Help please.

    Try changing the line button Add the following JavaScript code

    newRow var = Table1._Row1.addInstance)

    If (newRow.index > 0)

    {

    newRow.NumericField1.rawValue = newRow.resolveNode ('Row1 [-1].) NumericField1') .rawValue + 10;

    }

    You need to change this code to match your name on the form, but basically the method addInstance() returns the new row, the newRow.resolveNode ("Row1 [-1]... will get the value of the previous row and then add 10.

  • How to set the render property of the field on one facet of panelSplitter?

    Hi, experts,
    In jdev 11.1.2.3,.
    How to set the render property of the field on one facet of panelSplitter?
    -If the panelSplitter is reduced then make some fields in the second pane. otherwise, do not make these fields.

    It is not an easy job for me to set the EL expression.
    Thank you.

    OK, just did a small test case. It turns out that the difficulty is to automatically update the fields when the separator discloses. To add a pair of earphone client/server. This sends the event to disclose to the bean to update the fields.

  • How to set the output of the report to the session variable

    Hello
    Is it possible to output report to the session variable value. If my report returns 1 row and 1 column.

    I have a dashboard command prompt where I select name, but I want to find the ID of the same name.
    This ID I want to move to a Fx column, to achieve this, I created an interim report and I got the code. Now my problem is how do I put this ID in the session variable.

    Please help if anyone knows...

    Have you read this:
    How to set the session / presentation in the repository variable variable

    Dashboard invites on Month Name but the report on the ID of the month filter:
    Re: Guest dashboard on the name of the month but the report on the necessary month ID filter

    If you have dashboard guest (name), then you can have that one report that is filtered by a name but present card to display or not id but use id in the service. Or two reports as in the solution in the second link above and the second report has id in the function and filter by the id of the first report. You need not define this ID in the session for this example variable.

    Please close your previous discussions, if they are treated.
