ABSTRACT:
An electronic video measurement system for measuring three dimensional parameters of objects viewed by a two dimensional video image pickup. A borescope is provided in which the measurements are corrected for calibration, distortion, lens magnification, and system architecture. Programs and algorithms are provided for calculating various parameters of an object being viewed, including slant lengths and depths without the need for a scale positioned next to the object being measured.
