Abstract

A radiation detection device, also known as a particle detector, is a device used to detect, track and identify the presence of radiation sources within a given area or environment. In general, a stereo-radiation detection device consists with two radiation detection devices and used to estimate 3D distances to radiation sources accurately. In computer vision, device calibration is more important and to obtain accurate results using such devices, they have to be calibrated first. Many stereo camera calibration methods have been introduced throughout the last few decades but a proper stereo radiation device calibration method has not yet been introduced. In this work, we propose a new stereo-radiation detector calibration method using planar Homography. The calibrated devices are used to estimate 3D distances to radiation sources and we obtained very accurate results with an error of less than 6%.
