1. A system comprising:
correspondence mapping module that determines a dense correspondence map comprising feature correspondences between images sampled by an image acquisition system
a depth map module that determines a depth map based on the dense correspondence map and an epipolar constraint;
a miscalibration module that detects image acquisition system miscalibration when feature correspondences within the dense correspondence map deviate
from the epipolar constraint; and
a recalibration module that recalibrates the image acquisition system based on the dense correspondence map.
