Is anyone aware of an affordable 3D video camera (preferrably USB) that's good for outdoor use?

I'm designing a small outdoor rover, and I need a sensor that provides high resolution depth readings. Sensors like the Kinect don't work outdoors, and laser range finders are enormously expensive, so I'm looking at stereoscopy. I've cobbled together my own setup using cheap USB webcams, and although it works, the quality is quite poor, as expected.

I've seen some "3D Cameras" advertised for drones and quadcopters, like this one, but I've only seen them sold with a VR headset, and never with a USB interface. Would something like this work outdoors for stereo range finding, and if so, where would I buy just the camera?

I've also seen this ROS survey of 3D cameras, but it don't mention if the camera work outside.
