does the NoIR infrared camera produce gray-scale images/video ?

teddyyyy

this one:RPI NOIR CAMERA BOARD. - RASPBERRY-PI - 树莓派照相机电路板, NoIR, Version 2 | e络盟 中国

 

since it responds to IR light, I assume the output images/video is single-channel, i.e. grayscale?

 

does it respond to visible light at all? in my robotics application, I want my robot to respond to an IR beacon, so I would like to reduce the noise from visible light as much as possible, so is there some

filter to filter out visible light and retain only IR? 

 

also would it be possible to have multiple channels in the IR range? I would like my robot to distinguish between different IR beacons, so the easiest way to do this is to assign different wavelengths (color) to the IR beacons, but that requires the IR camera to have multiple channels

    As already stated it's just RGB where R is the whole range from  600-1000600-1000 nm

    You can of-coarse transfer them to grayscale by summing up the three color values.

     

    Regarding your question of filtering out the IR, yes that is perfectly possible. There are a whole lot of filters on sale, but also a small piece of exposed color film negative should work.

    People on the internet also mention using a piece of floppy disk.

    In this case you don't need to sum up G and B, because the values are 0, just take the red value.

     

    Maybe my characterisation of the original Raspberry Pi NoIR camera two years ago is also helpfull: Pi NoIR and Catch Santa Challenge - Review
