5. An endoscopic imaging and measurement system, comprising:
a probe placed in relation to an object of interest;
an optical system of said probe comprising at least one focusing lens and an electronic imaging device, said optical system capturing at least one image of said object of interest, and said at least one image being focused onto said electronic imaging device;
a display for displaying said at least one image of said object of interest;
said display further displaying a first measurement cursor overlay on said at least one image of said object of interest;
said display further displaying a first magnified view of a first portion of said at least one image of said object of interest concurrently with said at least one image of said object of interest, said first magnified view including a predetermined area surrounding said first measurement cursor overlay and a first magnified view measurement cursor overlay displayed at a position on said object of interest corresponding to the position of said first measurement cursor overlay on said object of interest, wherein said first magnified view does not obstruct said first measurement cursor overlay and allows placing said first magnified view measurement cursor overlay within said first magnified view to select a first measurement point on said object of interest; and
said display further displaying a second measurement cursor overlay on said at least one image of said object of interest to select a second measurement point on said object of interest, wherein said second measurement point is outside of said first magnified view;
wherein said first measurement point and said second measurement point are used for determining at least one geometric characteristic of said object of interest.
