Multi-ocular Stereovision

The binocular stereovision technology introduced in Chap. 4 refers directly to the structure of the human visual system. When using cameras for image acquisition, systems with more than two cameras (or one camera placed in more than two locations in succession) can also be used to acquire different images of the same scene and further obtain depth information. This technology is called multi-ocular (multi-eye) stereovision technology. Using the multi-ocular method is more complex than using the binocular method but has certain advantages, including reducing the uncertainty of image matching in binocular stereovision technology, eliminating the mismatch caused by the grayscale smooth region of the scene surface, and reducing the mismatch caused by periodic patterns on the scene surface.
