Abstract
Systems and methods for assessing the calibration of an array of cameras. The method including inputting into a processor captured images from at least two cameras of the array of cameras, the captured images having features from an image. The method further including extracting one or more extracted features from the captured images, matching one or more extracted features between pairs of the at least two cameras to create a set of matched features, selecting matching points from the set of matched features, generating a three-dimensional reconstruction of objects in a field of view of the at least two cameras, and outputting the three-dimensional reconstruction wherein the three-dimensional reconstruction comprises indicators of calibration errors.
