Raspberry Pi time lapse camera

===

Using the Raspberry Pi's [High Quality Camera module](https://www.raspberrypi.com/products/raspberry-pi-high-quality-camera/) I made a time lapse camera in my living room.

# Case

I designed a case with a large lens hood and a recessed lens so that it can block the light from the room.
This would allow the camera to take photos at night.

## STL files

The files are also available on [Thingiverse](https://www.thingiverse.com/thing:4684807).

# Capture code

I decided to strive for maximum image quality even at night, by capturing a stack of images and summing them up.

# Lens

I found a Basler C125-0618-5M-P on eBay which seems to have good image quality and fits the Raspberry Pi HQ Camera.

pic distortion.png distortion : The lens has significant barrel distortion but that is compensated for by my code above.

pic resolution.png resolution : The lens is quite sharp and can resolve even 200 lp/mm. This chart is at f/1.8, polychromatic, 0.5 m working distance.
