Abstract: An imaging system and methods are presented for determining a size of a viewed object through a monocular endoscope. The system includes an imaging device mounted on the endoscope, at least one light source disposed in a fixed position relative to the imaging device, and a processor configured to receive input from the imaging device and analyze at least one of shadow effect from the light source, structured lighting provided by the light source, multi-point illumination including the light source, time-of-flight involving light pulses from the light source, and lateral color aberrations from the light source to determine the size of the viewed object.
