Color Tracking using OpenCV and InRange Filter

Alessandruino's picture

Here is me with a tennis ball.. No filter is applied except Pyramid down to resize the video from the cam:

Here is as the ball appears after an InRange filter is applied... I had to tune HSV values in order to isolate the green of the ball...

Next is to find the center of the object and track it...

How can i do it?

Here it is last weekend before we wired and installed the glass. And yes that is a 1m x 1m heated bed.

I love my job.

Inside InMoov's Head

InMoov's head ... lots of spagetti in there :)
Anyway - there seems to be some issues with mouth control and the jaw servo - there were too many services and not enough hardware ...

Hopefully its ironed out.   I think there needs to be another way to display all this stuff (preferrably on the web) so we can see all the routes and messages.  This seems a bit crowded and it doesn't even have the left and right arms/hands/fingers.

First Test OpenCV with MRL services

Saymon Cristian Alves Oliveira's picture
My first test successfully ... all with the help of the developers of the MRL. 
As you can see .. More than 10 000 frames .. all that to properly configure the Pan / Tilt hahah
I can only thank .. and let's work!

Getting A-head on InMoov

Well I'm getting there. Wish I could make my printer go faster but don't want to sacrifice the quality.

Raspberry Pi Cameras and Faster Frame Rates

GroG's picture

Saymon asked if the Raspberry Pi module was compatible with MRL. By "compatible" I believe what he is asking is, "Is the Raspberry Pi module compatible with the OpenCV service of MRL".  The answer is no. OpenCV only supports cameras which support V4L (video for Linux) . 

To add to the confusion there is two interfaces for Linux V4L and newer not necessarily compatible V4L2.
