• How to follow the line with the vision of the webcam and move along in this

  Hello world

  I have a question that I can't really find a topic about it.

  Currently, I had made my rover robot wireless control using a 3-axis joystick and works perfectly.

  But I want to add some features to the vision on board the rover system.

  I'm doing the webcam to detect a black line on a white background, and then, he moves just independently along the the line black.

  The thing is that I only know abit about installation in a vision... So, if anyone here able to guide me on the way?

  I use filtering color or color matching or model of a match?

  How to make sure that the black line remains in the middle of the vision? (Eg. moving itself at the center of the line within his vision)

  How can I control the engines using the achievements of the vision of the foregoing?

  Hey,.

  Your questions:

  I use filtering color or color matching or model of a match?

  Pattern Matching or Color Pattern Matching would slow down.

  I would use a 1 d Simple edge detection that returns the coordinates and the edge angle.

  How to make sure that the black line remains in the middle of the vision? (Eg. moving itself at the center of the line within his vision)

  You must control your motors that for example the angle is 0 degrees or 90 degrees (depending on your coordinate system) all the time.

  How can I control the engines using the achievements of the vision of the foregoing?

  This robot manual should tell you how to control the motors.

  Hope this helps,

• How to compare the U2412M with the old 2407FPW?

  I had the 2407FPW since ' 07 and love it. I like the picture not bright. I'm about to order a new Dell and I wonder if the U2412M is comparable in quality? It has the same resolution (1920 x 1200), in contrast to the other Dell Ultrasharp 24 "monitor that is only 1920 x 1080.

  Joe

  2407WFP panels = S - PVA Samsung (LTM240M2) or THE Optronics AMVA (M240UW01)
  U2412M Board = LG e - IPS (LM240WU8-SLA2)

• How to compare, present value: block.text_item with the value of data

  Hello
  Could you please tell me
  How to compare the current value: block.text_item with the corresponding database column value.
  I use form 10g
  
  It has block and there is a text element in this block.
  When I run the form and query the block (in a table), the: block.text_item show me any value it in the database.
  Now I add value in the: block.text_item to the existing value.
  
  now
  the: block.text_item contains the old + new added value
  While
  the database table contains the value 'old '.
  
  Now, with a click of button, I want to know what value I added
  
  Please can you me, is it possible without writing a select query?

  Hello

  Now, with a click of button, I want to know what value I added

  So you're saying always user will bring added value to the existing value. Because it will fail in a case. Let's say that
  Database value is = ABCD
  The user opens the form and he took the D and write E and now value is ABCE and length is always the same 4. There is therefore no need to add.

  In any case, you can know that the value of database at run time, there is a property for the element called DATABASE_VALUE. She gives the value that is in the database while you run the form before save. and you can use it like that...

  Trigger = WHEN-MOUSE-DOUBLE-CLICK on item level
  DECLARE
    vItemValue DATATYPE; -- Set the data type according to your desired field.
    vValueAdded DATATYPE; -- Set the data type according to your desired field.
  BEGIN
    vItemValue:=GET_ITEM_PROPERTY('ITEM_NAME',DATABASE_VALUE);  -- It will return you the database value in vItemValue variable.
    IF LENGTH(vItemValue)>LENGTH(:FORM_ITEM_NAME) THEN  -- It mean something change or added
      vValueAdded:=SUBSTR(:FORM_ITEM_NAME,LENGTH(vItemValue)+1);
      MESSAGE('Added value is : '||vValueAdded);  -- It will show you the added value.
    END IF;
    -- now suppose you want to show the old and new value in message not the added one
    -- Then no need of IF condition. You can just use message like this
    -- And i would prefer to use like this way
    MESSAGE('Old Value : '||vItemValue||'  New Value - '||:FORM_ITEM_NAME);
    MESSAGE('Old Value : '||vItemValue||'  New Value - '||:FORM_ITEM_NAME);
  END;
  

  Hope that's clear.

• How to choose the line PFI to use on the port of the 5761?

  I understand that the VIDEO that I use on my DAC 5761 allows me to access 8 PFI lines.  However, when I access my 5761 devices in the project window by clicking the "+" next to the name of the module, I see that 'PFI Input' and ' output PFI.  I tried to get this to send a signal in the past, but I have been unable to determine how to select the line PFI I want to use.   How can I select the PFI line?

  Any ideas?  I was able to get the my AWG PFI (5422) for work and it is amazing.  I want to order an attenuator digital step for a ground penetration radar that I develop.

  Your time and your help is very appreciated.

  PS: I have worked with this PXI system (chassis, embedded controller, FPGA digitizer 5761 and AWG) for 1 year and I am afraid that it is time to learn this one way or another.

  Good day!

  -Daniel

  I found the solution. In addistion to the node which is visible in my previous post, there must be a node to enable PFI write with an entry of decimal number indicating the line is activated. Then, there must be a node PFI active connector, set to true. Not sure if the node of the latter is really necessary, however. Otherwise above examples should work as is.

  How to draw the line under STROKE and fill of an object in illustrator cc? Any ideas ...

  Aleksandar,

  If I (put) understand it, you will need to divide the object. You can:

  (1) select the object and Ctrl / Cmd + C + F, and then remove the filling of the copy and the blow of the original;

  Draw 2) and drag the new piece down between Division 1 objects) in the layers palette, or select 1 copy) and Ctrl / Cmd + C + F + X + F or similar.

• How to reach the line within the ellipse

  I have the following form:

  

  Which is an ellipse that happened to me to draw a line inside. My goal is to be able to join the line with the ellipse so I can do part of the form, so I cut the top of the ellipse (the part on the top of the line).

  Any help would be appreciated.

  Thank you.

  Fuck,

  If I understand correctly, in the right way, you can simply extend the line since the limit of the ellipse, the object > path > divide Onjects below, then remove the CAP.

  You can etxend the line by adding something to the value of W (or multiply by something) in the palette/Panel of transformation.

• How to fill the canvas with lines

  < mx:Canvas id = "b1" x = "10" y = "10" height = "40" width = "300" borderStyle = "solid" borderColor = "black" / >

  When I want to draw lines with difference of 15 pixels to fill the entire canvas I wrote the following

  for (var i: int = b1.x + 15; i < b1.x + b1.width; i = i + 15)
  {

• Select the lines with the maximum value for a date where another column is different from 0

  Hello

  I need to write a query on a table (called DEPRECIATION) that returns only the rows whose date maximum (PERENDDAT_0 column) for a specific record (identified by AASREF_0), and where the other column in the table called DPRBAS_0 is different from 0.

  If DPRBAS_0 is equal to 0 in all the lines of a specific record, then return the line with date maximum (PERENDDAT_0 column).

  To be clearer, I give the following example:

  Suppose we have the following data in the table of DEPRECIATION:

  AASREF_0	PERENDDAT_0	DPRBAS_0
  I20110010743	31/12/2015	0
  I20110010743	31/12/2014	0
  I20110010743	31/12/2013	0
  I20110010856	12/31/2016	0
  I20110010856	31/12/2015	0
  I20110010856	31/12/2014	332
  I20140012238	12/31/2016	445
  I20140012238	31/12/2015	445
  I20140012238	31/12/2014	0

  The query must return only the following lines:

  AASREF_0	PERENDDAT_0	DPRBAS_0
  I20110010743	31/12/2015	0
  I20110010856	31/12/2014	332
  I20140012238	12/31/2016	445

  Thanks a lot for your help!

• When I subtract two numbers DBL and try to compare the result with another DBL, it fails

  I found a curious problem with subtraction and compare numbers DBL in LabVIEW (8.6). Here's how it works:

  1. subtract two numbers DBL such that the result is not incorporated. (Say, 3.2 - 3.1)

  2. compare the result with a constant/control that is on the result of the subtraction (in the example, 0.1)

  3 see the output of the comparison.

  If the result of the subtraction is an integer, the Boolean result is (as expected). If the result is not complete, the comparison fails.

  (Now, if I simply compare two floating point numbers, it works, so the issue is not with the node comparison itself, but with the data that is entered to the node). Can someone understand why this happens? It's unexpected, it's a pretty serious bug.

  It is provided with all programming languages. Numbers do not have an exact binary floating-point representation. This has been discussed endlessly. Never use the equal function with floats. You can use the function in the range and force.
