Vision system with Labview, KUKA Robot, capture Image

[murty68]

Dear,

As a last year students we have a provocative project, where we must couple a vision system to KUKA robot.  We are from Belgium, so we can not write so good English.

At these project we use labview vision, the problem which rises is that we don't know how we can get picture from a camera on labview screen, i.e. detection or location of a object.

With  your aid we can complete our project successfully.

Thanks for your quick answer.

ask about the USB Camera VI, its not free though, so im not sure if your budget will allow for it.

First of all Thanks for your answer,

but we have already a camera(Ueye) ours problem is that we don't get the coordinates (i.e. cirkel detection, location of a object) from a object to the labview software screen. When we have the coordinates we will sent this one to the KUKA robot. So the robot can move to this place for pick up the object.

Thanks...

I have done something similar to align and focus a laser.  The VI looks at the x-y co-ordinates and also measures the radius and roundness of the spot.  You may have difficulty finding an object if your lighting isn't correct.  You should select a plain background to maximise the object you are trying to detect. 

For information we use a Watec 902-B analogue CCIR camera and a PCI-1409 IMAQ card.  You will need Vision development software (at least version 7) as well as Labview.  You will also need IMAQ software and you may need other software if your camera is FireWire or USB.

The VI was writen in version 7.1.

I hope it points you in the right direction.

Dan, firts of all Thanks for the information,

We will follow yours information and test the example as soon as possible.

best regards

Sorry, our Camera VI only feeds the video to labview. We have several VI's that can handle image recognition though.

Hi murty68,

did you try the example from Dan? Where are your problems at the moment?

Karem,

Sounds like there are plenty of people willing to help you, but you really haven't given us much information about your system.

If you let us know what hardware (ie camera type - analogue, USB or Firewire and interface if any) and software (labview version, Vision development module version and IMAQ software) you are using we may be able to hlp you further.

A better description of the problem and some example code that you're trying to use would also help.

Dan,

we can explain ours project:

- Camera, Gigabit Ethernet uEye UI-6220 models, CCIR (768x576), here is also the link http://www.ueye.com/frontend/catalog_detail.php?pID=762&form_KatTable=menue3&form_KatID=58&nav1=25&n...#

-Software: labview 8.5.1, NI vision 8.5.0, NI imaq 4.0.0, Vision builder 3.5.0

At these project we use labview vision, we use here serial cable for comminication with the robot KUKA, we can send 3 coordinates to the robot( X, Y, Z coordinates) so the robot moves to this coordinates.

But now the problem is, we use labview vision and a camera, with this camera(Ueye) we must get the coordinates of image(object) that we get from the camera on labview,

So will send this coordinates to the robot. But how can we get this coordinates on labview. Can someone send a example vi, an information or a solution
