Video monitoring method of 3-dimentional intertidal beach

摘要

The present invention relates to a three-dimensional intertidal topographical observation method, comprising: continuously photographing a landing boundary line that changes with time during high tide in an intertidal zone (S1); Geometrically correcting the continuously photographed image by adjusting previously measured coordinates (S4); Automatically extracting the landing boundary from the continuously photographed image (S5); And calculating spatial coordinate data on the extracted land boundary (S6). It is characterized in that it includes, and at a very low price to enable the three-dimensional terrain observation of the effective and precisely widely distributed intertidal zone.;Intertidal zones, three-dimensional terrain, digital images, geometric correction, automatic extraction,
