An imaging system, comprising: an imaging scope extending along a longitudinal axis between a proximal end portion and a distal end portion thereof, the imaging scope selectively rotatable about the longitudinal axis relative to a horizon plane, the imaging scope having at least three optical channels (28, 30, 32), each including a respective objective (34, 36, 38) positioned at the distal end portion of the imaging scope, and each configured to capture light reflected from an object, the objectives (34, 36, 38) of the at least three optical channels (28, 30, 32) being annularly-spaced relative to one another and positioned such that respective viewing direction axes of the at least three optical channels (28, 30, 32) extend parallel to one another; a controller configured to activate, among the at least three optical channels (28, 30, 32), a pair of optical channels (28, 30, 32) defining a viewing horizon line that is at least as parallel relative to the horizon plane as that of any other pair of optical channels (28, 30, 32) among the at least three optical channels (28, 30, 32), the viewing horizon line being a line that extends perpendicularly between the respective viewing direction axes of a pair of optical channels (28, 30, 32) of the at least three optical channels (28, 30,32); a camera configured to generate a first 2D digital image representative of light captured by a first optical channel of the activated pair of optical channels (28, 30,32), and a second 2D digital image representative of light captured by a second optical channel of the activated pair of optical channels (28, 30, 32); and a 3D processor configured to generate a 3D digital image using the first 2D digital image and the second 2D digital image. an imaging scope extending along a longitudinal axis between a proximal end portion and a distal end portion thereof, the imaging scope selectively rotatable about the longitudinal axis relative to a horizon plane, the imaging scope having at least three optical channels (28, 30, 32), each including a respective objective (34, 36, 38) positioned at the distal end portion of the imaging scope, and each configured to capture light reflected from an object, the objectives (34, 36, 38) of the at least three optical channels (28, 30, 32) being annularly-spaced relative to one another and positioned such that respective viewing direction axes of the at least three optical channels (28, 30, 32) extend parallel to one another; a controller configured to activate, among the at least three optical channels (28, 30, 32), a pair of optical channels (28, 30, 32) defining a viewing horizon line that is at least as parallel relative to the horizon plane as that of any other pair of optical channels (28, 30, 32) among the at least three optical channels (28, 30, 32), the viewing horizon line being a line that extends perpendicularly between the respective viewing direction axes of a pair of optical channels (28, 30, 32) of the at least three optical channels (28, 30,32); a camera configured to generate a first 2D digital image representative of light captured by a first optical channel of the activated pair of optical channels (28, 30,32), and a second 2D digital image representative of light captured by a second optical channel of the activated pair of optical channels (28, 30, 32); and a 3D processor configured to generate a 3D digital image using the first 2D digital image and the second 2D digital image.
