The system will provide you with all the measurements of anything in front of the camera, a revolutionary tool. This is called the Image+. The system uses a stereoscopic camera with over-and-under lenses spaced six or eight inches apart. This is a rather different approach to something like the widely-used Cinetape, which relies on timing echoes of ultrasonic sound to determine distance (and which is not generally used to directly control the lens). 

The key advantage of this is that it produces a complete depth image, not just a point reading. Qinematiq have used this to provide a touchscreen interface in which any object in the field of view can be brought into focus simply by touching it. The conventional, visible-light image is overlaid on the depth map. 

As with any stereoscopic depth camera, the depth image is noisy and overlaying the visible-light image makes things easier to recognise.

The other use of the visible-light image is in feature tracking, wherein the system will do what it can to keep an object in focus by tracking its image around the field of view, focussing to the distance indicated by the depth map in that location. Doing this naturally requires that the lenses are properly mapped – that is, the system must know precisely which focus distance is represented by which rotational angle.

The accuracy of the system is20mm at 4m. This will accommodate most common situations, the maximum range of the system is15m.
