Short summary
Geoscientists working with drill cores often struggle with proper photo documentation. We present a simple smartphone-based setup for acquiring high-resolution undistorted core pictures as an alternative to state-of-the-art commercial line scan imaging systems that are typically expensive and inflexible. It makes use of the phone's panoramic picture mode while being guided along the core in question on a rail, and the resulting images are of similar quality to classic line scan photos.
