Single-cannister underwater stereocamera system with distance measurement function

摘要: A single-canister underwater stereocamera system with a distance measurement function is disclosed. In the camera system, drive unit, holding two cameras on its base, set in parallel space defined between support plates, and operable by motor thus being movable along to front or back. lens lenses bases, be unit so as laterally move left right under guide of linear bearing. The controls focus length each moving at same time. actual an target object from measured sensing rotated position encoder taking advantage fact that has functional relation 1:1 cameras. This measures while compensating for refraction errors light beams passing through both window water. also encased within waterproof pressure-proof cylindrical canister having transparent end wall. effectively usable deep sea.
