APPARATUS FOR MEASURING DYNAMIC DISPLACEMENT OF FLOATING STRUCTURE AND VISION-BASED UNIT THEREOF

摘要

The present invention relates to a floating body dynamic displacement measuring apparatus, comprising: a marking unit having four or more identifiers on a surface thereof, and having three or more marking units arranged on top of the floating body with the same size; Two or more units spaced apart from the floating body, two marker units arranged in a line of the three or more marker units in one image, and the two marker units taken in one image An image-based unit for recording the position of each recognizer provided in coordinates; And a calculation unit for calculating the six degree of freedom dynamic displacement of the floating body by comparing the positions of the coordinates recorded in the image-based unit.
