Calcam is a Python package providing tools for "spatial calibration" of cameras used in science & engineering, i.e. determining the mapping between pixel coordinates in an image and real-world 3D sight lines & coordinates. The calibration method is based on the user matching features between an image to be calibrated and a 3D mesh of the scene being viewed, then using OpenCV’s camera calibration routines to fit a model relating the image and real world coordinates.
It was written for use with camera-based plasma diagnostics on fusion experiments, but may be useful for other applications too. As well as calibrating existing cameras, it can also be used as part of a virtual diagnostic setup, e.g. to evaluate different possible viewing geometries during diagnostic design and/or setting up synthetic imaging diagnostics for modeling codes.
Calcam provides a set of GUI tools for calibrating images and doing some basic analysis using the results, and a Python API for making full use of the calibration information as part of a data analysis process.
