Marine plant field survey method and survey system utilizing the survey method

摘要

A marine plant field survey method includes the step of using a submarine mobile video system capable of taking images underwater to measure degree of macrophyte coverage in a marine plant field by taking wide-field images of macrophytes from above and a step of using the submarine mobile video system to discriminate species of macrophytes by taking images of macrophytes from a direction other than from above. A marine plant survey system includes a camera for taking wide-field images of macrophytes from above and a camera for taking images of macrophytes from a direction other than from above.
