Abstract
A control system for controlling the movement of a machine element of a construction machine may include a camera support, a plurality of video cameras, a processor responsive to the cameras, and a control for providing control signals. The camera support is adapted for attachment to a movable construction machine. The plurality of video cameras are mounted in a row on the camera support, with the cameras being directed downward to define overlapping fields of view beneath the row. The processor determines the relative position of a point of interest on a surface in the overlapping fields of view of at least two adjacent cameras. The control provides control signals for controlling the movement of the construction machine in dependence upon the relative position of the point of interest.
