An imaging system (10) includes an imaging scope (12), a controller (14), a camera (16), and a processor. The imaging scope (12) is selectively rotatable about a longitudinal axis (20) relative to a horizon plane (26). The imaging scope (12) has at least three optical channels (28, 30, 32), each including a respective objective (34, 36, 38) that captures light. The objectives (34, 36, 38) are positioned such that respective viewing direction axes of the optical channels (28, 30, 32) extend at least substantially parallel to one another. The controller (14) activates a pair of optical channels (28, 30, 32) that is at least as parallel relative to the horizon plane (26) as any other pair of optical channels (28, 30, 32).The camera (16) generates a first image representative of light captured by a first optical channel of the activated pair of optical channels (28, 30, 32), and a second image representative of light captured by a second optical channel of the activated pair of optical channels (28, 30, 32). The processor generates a 3D image using the first and second images.
