摘要: Two planar mirrors are positioned to show five views of an object, and snapshots captured from different viewpoints. We present closed form solutions for calculating the focal length, principal point, mirror camera poses directly silhouette outlines object its reflections. In noisy case, these equations used initial parameter estimates that refined using iterative minimisation. The self-calibration allows visual cones each be specified in a common reference frame so hull can constructed. proposed setup provides simple method creating 3D multimedia content does not rely on specialised equipment. Experimental results demonstrate reconstruction toy horse locust real images. Synthetic images quantify sensitivity quantisation noise. terms calibration ratio, degradation quality has greater effect set consistency than computed parameters.
