Abstract: A method for measuring a liquid volume and/or corresponding fill rate of floating roof tanks includes selecting an Area Of Interest (AOI) to be monitored at the earth's surface, gathering geographical coordinates of tanks in the AOI, and downloading and pre-processing a time series of SAR reference images covering the AOI. The method includes projecting geographical coordinates of the tanks on the time series of the images to determine pixel coordinates of the tanks, and determining tank dimensions through processing of the images at the pixel coordinates. The method includes downloading and pre-processing at least one new SAR image over the AOI and registering it on top of the reference images, and, for each tank of the AOI, detecting in the new SAR image a bright spot corresponding to the roof of the tank and converting its pixel coordinates into liquid volume and/or fill rate information.

Abstract: Information of different scans of physical objects may require comparison, for example to determine if the scans are of the same object or if an object has changed, or better information for a three dimensional model may be desired. Different scans of physical objects may be compared by determining lines or planes tangent to a surface at a discrete number of points, registering three dimensional information provided by the scans using the tangent lines or planes, and determining a measure of discrepancy between the surfaces. Three dimensional information of different scans of the same object may also be merged after determining lines or planes tangent to a surface at a discrete number of points and performing registration and merging.

The means for moving the element includes a support and an element gripper member. The gripper member has a vertical axis that is perpendicular to the surface of the substrate and is mounted to move freely in translation on the support in a direction parallel to its vertical axis. The measurement means measures a variation of the position of the element in vertical translation.

Abstract: In this method, a vertical stack is formed on an axis coinciding substantially with the gravity direction and comprising, from top to bottom: the element; the mass in a solid state; and the substrate. The mass is then heated so as to cause it to pass into a liquid state enabling it to spread on the substrate. More particularly, after the stack has been formed, the element is left free to move vertically, and during heating, variation in the vertical position of the element is measured.
