Re: StereoPi and Arduino I2C

Figured it out. Was missing external power on Arduino. Supplied extra 5V to the board and it's now working.

StereoPi and Arduino I2C

Hello! I'm trying to send data to Arduino from StereoPi through Serial connection and then send it through Arduino's I2C but for some reason I can't make it work. Basically the workflow is: Pi data --(serial)--> Arduino --(I2C)--> receiver I was able to make it work when the Arduino is connected to ...

Re: Getting Actual Distance Data (in cm) from Depth Map

Wow! Thanks for your responses! I actually tried the triangulation formula but wasn't sure what to do with all the values since we get one per pixel. I will check out the "reprojectImageTo3D" function and will get back with my results. I'll also look into the 7_2d_map.py. Your codes are very user-fr...

Getting Actual Distance Data (in cm) from Depth Map

Hi! Our team has just bought 3 StereoPi kits for our robots. We are trying to make an altitude sensor. We thought about using the Depth Map to get depth data but we're not sure how to get the exact distance (in cm) of each pixel in the depth map. Any suggestions on how to do this? Thank you!
