Parameter error analysis of single-lens prism-based stereovision system

In this paper, the quantization error and parameters of the single-lens prism-based stereovision system are studied in detail. Each image captured using this system can be divided into two subimages on the left and right, and these subimages are generated by two virtual cameras that are produced by the biprism. This stereovision system is equivalent to the conventional two-camera system and the two subimages captured have disparity that can be used to reconstruct the 3D scene. The relative range error of this system is studied with respect to the system parameters, which gives us a better way to quantify the range resolution of the system and enables the selection of system parameters to become easier.
