Hi OpenMV friends, I’m new here.
Is there by any mean, a way to keep memory from frame to frame of the blob id ?
Here is the idea : we’re trying to use the OpenMV H7 + Teensy as a HID multitouch system for windows10 or linux native (fav choice)
We’re able to track an IR pointer as a blob diffusion through a flat video projection screen.
For the moment we only manage to track the position of the IR pointer to move the touch point for only one mouse pointer.
We would like to press and hold while the blob (the light is emitted) is active (like a wii-mote multitouch screen hack if you already seen that)
So there 2 ways we can do it :
- either by computing a lot in the Teensy doing math to track blobs from frame to frame : hard one
- track the blobs going on and off on the OpenMV Cam (and implement a cleaner Reactivision/TUIO-like protocol) : easy one if it exists
Any help on this ?
Thank you so much in advance
