Some embodiments are related to a system for estimating a harvest volume in a vineyard operation organized into rows of vine stocks, including: a photographic device for capturing a photographic image of a set of stocks when the system passes between two rows of the vineyard operation; a device for measuring a distance between the vine stocks and the photographic device; and a calculator for detecting the berries within the photographic image, determining a number of berries in a bunch, determining a number of bunches on a stock, and determining an indicator of the volume depending on the number of berries in a bunch, the number of bunches on a stock and the diameter of the berries determined from the photographic image and the distance measurement.

System and method for estimating a harvest volume in a vineyard operation

The invention pertains to a method for enhancing the determination, from a seismic image of at least a portion of a seismic horizon in a three-dimensional domain. The method comprises: receiving the seismic image; receiving a plurality of related control points; defining pseudo-rectangles; for each pseudo-rectangle applying a diffeomorphic transformation F: defining a new domain; transforming points of the seismic image; transforming said pseudo-rectangle into a corresponding rectangle; applying a horizon reconstruction algorithm to the transformed points, to determine a part of a transformed horizon, the reconstruction comprising solving a Poisson equation; and computing a part of the horizon, said computing comprising applying an inverse diffeomorphic transformation Fto the determined part of a transformed horizon.

Method for enhancing the determination of a seismic horizon

The invention targets in particular a method for searching for a seismic horizon in a seismic image of the subsoil. The method notably comprises the designation of two points belonging to the horizon sought, the iterative search for the best solution for the equation of the seismic horizon notably by virtue of a breakdown of this solution into two components, a pseudo-continuous component and a jump component.
