ENDOSCOPIC VISUALIZATION DEVICE, SYSTEM, AND METHODS

Imaging devices, imaging systems, and methods are presented for determining distances, depths, and sizes of a viewed tissue or object through a visualization device. The device may include an elongated shaft and an imaging component. The imaging component may extend through the elongated shaft. The imaging component may have a lens and may be configured to capture an image of an area exterior of the elongated shaft in a field of view of the lens. A transparent cover may extend over the lens. The transparent cover may be configured to cause one or more identifiers to appear in the image. The imaging device may include or be used with a computing device to analyze image data of captured images.
