Method for determining the orientation of a submerged surface and apparatus that carries out this method

摘要: A method for determining the orientation of a submerged surface (210) comprises steps arranging an underwater support (10) in position arranged at predetermined distance from (210); spatial and depth above described position; constructing virtual image (210). In particular, step of: projecting least three points (101a-101d) laser light on acquisition projected by optical sensor (25) mounted obtaining (130) comprising (131a-13ld) corresponding to said (101a-101d); processing (130). identifying geometric figure which belong (131a-131d); detecting shape figure; computing basis detected identified
