Messing about with the Raspberry Pi NoIR Camera

the48sicks

For a moment, it felt like i was guiding the mars rover!

 

 

I bought the NoIR camera about 12 months ago for another project and wondered how i could incorporate into my robot somehow. I swapped out my normal camera that i use for my OpenCv work and dropped in the NoIR camera, Now in the past i have tried using some of the small IR lamps and LED units but they never really delivered the results i was looking for so i found an IR FLOOD LIGHT and mounted that on a deck for giggles to see how it would work and my word - the results were amazing! This thing lit up the place like a runway landing light.

To the human eye, you only see little red lights in the LED's but my android phone caught the full power of this thing.

The power for the flood light is switched by a relay mounted under the deck, but the unit also had a built in light detector, good for saving juice while running on batteries!

It would be cool if there was some way that i could easily switch between a normal and a noIR camera. I think its called an auto-switching or cut filter. at the moment i just have it blue tacked onto the front of the normal one and switch the ribbon between the two  image

    Thanks DAB - Might take a  look into it, see if there is a way i can mount a servo to switch it out

    What you are seeing is the sweat transfer through your shoe soles to the floor.  The sweat retains the heat from your body that slowly dissipates as the sweat dries and the area cools.

     

    I look forward to your future posts.

     

    PS, if you want to just see the IR with the NOIR camera, use a No.25 Red filter.  It will block everything below about 750 Angstroms leaving just the near IR wavelengths.

  • You could use an IR block filter and a servo to drop it down in front of the camera when you just want regular RGB images.
