How to test the length of the line

Hi all

I want to test the length of the line, the next photo, I use the wizard of vision and no to do, but I can't get the result, any help is very grateful.

Hi longzeng,

Are you still looking for a solution to this problem. I think that the best method of Vision Assistant will be on the threshold of the image and then perform an analysis of the particles on the result. The stage of analysis of the particles will have a very large selection of outputs possible. I picked the ones that will probably be the most interest in Vision Assistant script attached below. You may need to make some adjustments to get reliable and consistent performance of the thresholding step, but I believe that this will happen the feature you're looking for.

Please let me know if you have any questions on this.

Thank you

  • 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!

    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 specify a length of straight line with the Brush tool

    Hello

    I want to draw a few straight lines that have the same look as the paint brush tool. that is the ends of the lines have rounded ends.

    The thing is, I want to be able to specify the length of these lines.

    (1) can I do this with the paint brush tool? So be specific with the length of the line, for example that I can specify in some fields or something like that?

    (2) otherwise, I use the online tool to look the same as a line of paint brush?

    David.

    Hi David.

    Option 2:

    Select the line Segment tool (shortcut "------"). Click the origin. The dialog box should open. Specify the length. Apply a line with round cap. Adjust the width of the line and color to your liking.

    I hope this helps.

    Peace,

  • How to test the stored procedure in SQL Developer or SQL Plus

    Hello

    It's small, but I am confused. Can someone give me the EXACT command to run to test my stored procedure described below. Please don't refer me to the documentation or offer some sort of pseudocode. I've been through the documentation - and through it again - and I just don't get it. I know that the procedure works in general because I'm calling ColdFusion, but I want to test developer SQL or SQL more before I call my ColdFusion page - it only makes sense. I'm probably not initialize variables right or something - not sure.

    You will see that it is a line right insert in the firstname and lastname data base and there are 2 IN OUT values as well. Please use a fake name for the firstname and lastname values to demonstrate. I appreciate it!

    create or replace
    procedure sp_insertDirector_A)
    vFirstname IN Directors.Firstname%TYPE,
    vLastname IN Directors.Lastname%TYPE,
    vInsertStatus in on NUMBER,
    vNewDirectorID IN OUT NUMBER
    )
    IS
    row_count NUMBER;
    BEGIN
    SELECT Count (*) FROM directors WHERE Lastname vLastname = row_count;
    IF row_count > 0 THEN
    vInsertStatus: = - 1;
    RETURN;
    END IF;

    INSERT INTO administration)
    FirstName, Lastname)
    VALUES)
    vFirstname, vLastname
    );

    SELECT Directors_Seq.CURRVAL INTO vNewDirectorID FROM DUAL;
    vInsertStatus: = 1;
    END;

    If someone can tell me exactly how to test, I'd appreciate it. I asked on another site and got many responses that I tried and did not work due to various errors. Once I get a working example, I'm sure I can get the idea and continue on. I mainly use the SQL Developer.

    Thank you, mallethead

    p.s. I think that my if - THEN followed by the instruction INSERT is fixed - it is woring. Seems a little odd to me however.
    declare
       l_instatus  number;
       l_newdirid  number;
    begin

  • How to test the switching PXI matrix

    Hello

    I have a PXI-2530 b and I was wondering is there an accepted practice to check the viability of relay out to just look at the number of relays?  I want to know if I've damaged a relay.  From what I read so far, I have to create my own connection matrix of switching to my PXI-4071 DMM test harness to check the status of network.   Is there another way.  NOR has considered adding a self-test for relay condition?

    Thanks for your quick response.

    I thought as well, but I wanted to be sure.  Even if I know that the reeds have a long service life, it is possible have to explode or cause damage.   And since there is no procedure for calibration to the switching matrix, I was wondering how to check that this component of the system is still usable.   We use the PXI system as a way to test and calibrate an internal pacemaker tester with 112 connections.  We partition the 2530 b in 5xBlocks, 1xBlock and 2xBlocks in independent mode and then using a custom internal test adapter to provide all interconnections.  The DMM and the multi-IO are distributed in these partitions.

    For this reason, I would recommend that future matrix systems have a rudimentary way to self-test the relays are less than 3 ohms (or all that apply regarding a particular switching matrix).   Pickering is advertising for cards supporting Birst.

  • How to test the stability of the communication and to calculate ber using the CVI?

    Our Chief Engineer gave me a task yesterday. He asked me to make testing of software and to calculate the error rate binary we would like to know our stability of communication.

    However, I never touched this aspect of knowledge. I know a bit about the CVI and I want to write code with CVI bit error rate. So I could test the stability of the communication.

    But I don't know how to analyze and judge the receivers codes, whether they are good or bad.

    We use the Modbus communication protocol and receive data via a port series, so I want to back up all the data and record the total number of datas, marking as M.

    then, save the eligible data and save the number marking as N. Thus, the error rate is binary/m (M - N).

    If it's doable? Or you have a good idea. Thank you very much.

    unsigned char in_data[100]; 
    
     inqlen = GetInQLen (comport);
     for(i=0;i
    

    Above is my code that receives all the data I want to save the data [] array in_data and save the number.

    switch(inqlen)
    {
     case 19:
     {
       crc=usMBCRC16(in_data,inqlen );
       if((in_data[1] == 0x03)&&(crc==0)&&(in_data[0]==device_addr))
        {
    
        }
     }
    

    Above is the judgment of condition who receive eligible data which mark as N number.

    I know there is a prerequisite that I filter all the bad data. However, I don't know any good idea. I'd appreciate if someone could help me.

    Thank you very much.

    Best regards.

  • 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 test the app on BB10 2 phones with unique SIM without was anything!

    Howdy. I'm quite new to the BlackBerry Development (and especially new to BlackBerry phones), so I answered a few questions that I need. I had a Z30 for awhile (and I compiled/deployed some examples of applications that it), and I just bought a Q10 I can do 'real life' tests on smaller screens. I don't have a Micro SIM I want to switch between these phones (so I can choose my "daily driver"), but I am concerned about the effect of swapping phones will have a general user, both in terms of developer level.

    -If I put the SIM in my new Q10, it "lock" development on this phone, which prevents me to test on the Z30 or will I prevented from developing on the pins are different? My BlackBerry ID is linked to the PIN? How to acquire development chips do not work when swap you a SIM card between 2 phones?

    -How to replace the SIM card from another phone BB10 affects bought apps? I'll be able to install applications on both phones (and does it make a difference if only one of the two phones is turned on at the time)?

    -Do I need a BlackBerry ID for each phone, and if it is true, how will this affect the actual process of the build/deploy/debug?

    Basically, I want to be able to use a telephone for general use and test one or more applications on both phones, and I have no idea how all this works together (or does not) when several phones are at stake.

    The Z30 running 10.3.1 last build of the OTA and the Q10 runs the last 10.2.1 OTA build (10.3.1 soon?).

    I'll wait to complete the process of implementation on my Q10 until I hear something.

    Thanks in advance for any help you can provide me.  Thank you!

    Thank you very much!  I will give that a shot. (I may be a response to follow-up later - hang )
