1. A multi-channel imaging system comprising:
an array of at least two cameras, wherein at least two channels are distributed across the at least two cameras;
an imaging distance sensor adapted and configured to image a field of view similar to a field of view imaged by the at least two cameras and to obtain depth information that includes a spatially resolved point cloud across the field of view of the imaging distance sensor; and
a processor configured to store camera calibration information regarding the at least two cameras, wherein the camera calibration information is defined in a coordinate system relative to the imaging distance sensor;
wherein the processor is configured to receive image signals from the at least two cameras and the depth information from the imaging distance sensor and to use the depth information and the camera calibration information to correct for parallax between the at least two cameras, thus providing a multi-channel image that appears to originate from a single viewpoint.
