Hi everyone,
I'm trying to write a GUI in c# that obtains information from a USB webcam. Since I 've got a ezb4 no so long ago, I'm aware what the sdk can do in terms of image processing and object recognition. But I'm contemplating between should I use sdk or emguCV to do my project on. So what do you guys recommen? (my project described below) Secondly, I've downloaded the sdk zip and have a brief look on the examples in the folders, but I'm wondering is there any proper tutorial /videos anywhere here, so I could properly learn the functionality of the sdk (I'm reasonably new to c#).
What I need to do for my project is, I'll have a 8 joint link robotic arm (that will be physically build) and a overhead usb webcam. Both of which will be link to a pc. What I wanted to do with the arm is, when the GUI runs, the webcam will continuously stream video to a picturebox in the GUI. Then when a ping pong ball is presented within the workspace of the arm, the GUI will recognise the ball and drive the arm to pick up the ball.
Thanks.
I literally provided you a complete working code with object tracking and everything
did you not see it?
All you have to do is copy and paste my code into your project - and the ONLY piece that you need to edit is the movearm() method for moving servos. That's it - the entire project is done and right there in this thread.... object tracking and everything.
@DJSure, I just saw it.
Okay wicked - so all you have to do is fill in the math for the servos to move the paddle into the x/y position. That goes in moveArm()...
I built a little tiny prototype with bits for fun to test with....
Oh, this gives me ideas! PaddleBots!
@JustinRatliff , when you brought the idea of paddlebots up. I have that image of 2 bots playing that classic arcade game call pong. Don't know why.
@DJSures, I'll work on that over the weekend and keep updating and/or posting if I got into come complications
Okay now that's awesome - computer vs computer with real life pong? I like it!
Philip, the toughest part will be filling in the code for moveArm(). Because you will need to calculate how to move the servo joints to reach each x/y relative coordinate.
Lastly, if you find the object isn't tracking "perfectly", the Size and Brightness can be adjusted with the GetObjectLocationByColor() parameters. I would recommend adding trackbars to configure those two values realtime.
