A stereoscopic camera with fluorescence visualization is disclosed. An example stereoscopic camera includes a visible light source, a near-ultraviolet light source, and a near-ultraviolet light source. The stereoscopic camera also includes a light filter assembly having left and right filter magazines positioned respectively along left and right optical paths and configured to selectively enable certain wavelengths of light to pass through. Each of the left and right filter magazines includes an infrared cut filter, a near-ultraviolent cut filter, and a near-infrared bandpass filter. A controller of the camera is configured to provide for a visible light mode, an indocyanine green (“ICG”) fluorescence mode, and a 5-aminolevulinic acid (“ALA”) fluorescence mode by synchronizing the activation of the light sources with the selection of the filters. A processor of the camera combines image data from the different modes to enable fluorescence emission light to be superimposed on visible light stereoscopic images.

A system and methods for attaining optimal precision digital image stereoscopic direction and ranging through air and across a refractive boundary separating air from a liquid or plasma using stereo-cameras, and employing a minimum variance sub-pixel registration method for determining precise estimates of the parallax angle between left and right stereo images. The system and methods can also track measurement and estimation variances as they propagate through the system in order to provide a comprehensive precision analysis of all estimated quantities.

The technology described herein can be embodied in a stereoscopic endoscope in which the orientation of the two eyes may be determined dynamically as the endoscope is moved and rotated. This may enable an improved user-experience when using an angled stereoscopic endoscope even when it is rotated, for example, to view the sides of a cavity.
