Abstract:

This report considers the theoretical analysis of measurement errors introduced in an underwater stereopsis system which has front window misalignment. It develops new range and size equations and models the effects of window misalignment, range equation approximation and system sampling effects. A scheme is given which will allow underwater calibration in a practical system. The report concludes that the new range and size equations developed provide enhanced accuracy to a point where the system sampling effects become the dominant source of error.
