Abstract: A stereoscopic imaging platform includes a stereoscopic camera configured to record left and right images of a target site. A robotic arm is operatively connected to the stereoscopic camera, the robotic arm being adapted to selectively move the stereoscopic camera relative to the target. The stereoscopic camera includes a lens assembly having at least one lens and defining a working distance. The lens assembly has at least one focus motor adapted to move the at least one lens to selectively vary the working distance. A controller is adapted to selectively execute one or more automatic focusing modes for the stereoscopic camera. The controller has a processor and tangible, non-transitory memory on which instructions are recorded. The automatic focusing modes include a target locking mode. The target locking mode is adapted to maintain a focus of the at least one stereoscopic image while the robotic arm is moving the stereoscopic camera.
