ECPC – versatile multicamera system calibration framework for immersive video applications

Abstract

Accurate extrinsic parameters calibration is crucial particularly in immersive video, where camera calibration plays a significant role, as its quality is essential for accurate reconstruction and efficient compression of three-dimensional scenes. While methods for intrinsic parameters calibration, color correction, and depth estimation are publicly available, there is a lack of versatile techniques for estimating extrinsics in the context of immersive video. The proposed Extrinsic Camera Parameters Calibration (ECPC) software addresses these limitations by proposing an extrinsic parameters estimation method and a framework for testing its accuracy. The software is compatible with MPEG Immersive Video framework, allowing for seamless integration and evaluation. The proposed method contributes to the advancement of immersive video applications by providing a reliable and comprehensive approach for estimating and evaluating extrinsic parameters.
