In need of a wide lens camera for my homemade Tile-o-matic machine

Hello fixers, i run Norways smallest tileshop where we specialize in Maroccon handmade tiles, we got over 400 tiledesigns so we needed to make a machine, where the customer could project one tile into a bigger picture of more tiles. I made the machine , but i need a wide lens camera for my raspberry pie.
