FLUID STORAGE MONITORING

原文（中文）

A method of monitoring the stored volume of a fluid in a storage container having a lid resting on the surface of the fluid stored, the method comprising: receiving a plurality of sets of image data collected by one or more satellites in orbit around the Earth, wherein each set of image data corresponds to a respective synthetic aperture radar image of an area on Earth that includes the storage container; grouping the plurality of sets of image data into one or more groups based on one or both of the direction of travel and/or the look direction of the respective satellite that collected the set of image data; and for each of the one or more groups: geometrically aligning at least two of the sets of image data within the group to define a stack of aligned image data; identifying. in the stack of aligned image data a feature corresponding to a point on the bottom edge of the storage container; geometrically aligning another set of image data from amongst the plurality of sets of image data with the stack of aligned image data; identifying. in the another set of image data, a feature corresponding to a point on the lid; and determining, based on the identified features, an estimate of the height of the lid relative to the bottom edge of the storage container.
