1. A system comprising:
a first sensor system configured to:
receive first image data of a scene captured by a pair of camera sensors,
calculate first disparity values and first confidence values from the first image data, and
output a first disparity map comprising the first disparity values, and output a first confidence map comprising the first confidence values; and
a machine control system configured to output a first control signal to a control unit of the machine to control the machine based on the first disparity map and the first confidence map, wherein controlling the machine based on the first disparity map and the first confidence map comprises determining whether to use the first disparity values or discard the first disparity values based on an assessment of the corresponding first confidence values.
