Abstract
A depth imaging device is provided. A first camera and a second camera form a first depth imaging system. A projection element and a second camera form a second depth imaging system. The control unit is configured to instruct one of the first and second depth imaging systems to acquire a depth map and a confidence map, and determine whether each of confidence values in the confidence map is less than a confidence threshold value. If each of the confidence values is less than the confidence threshold value, then the control unit turns on the other of the first and second depth imaging systems. If at least one of the confidence values is not less the confidence threshold value, then the control unit determines whether a closest distance in the depth map falls within a predetermined range or not. A driving method of a depth imaging device is also provided.
