Title: François Gaspard: Innovator in Image and Motion Sensor Technologies
Introduction
François Gaspard is a notable inventor based in Les Ulis, France. He has made significant contributions to the fields of image processing and sensor technology, holding a total of 3 patents. His work focuses on integrating data from various sensors to enhance localization applications and improve inspection methods.
Latest Patents
One of Gaspard's latest patents is a method and system for fusing data arising from image sensors and motion or position sensors. This innovative approach integrates inter-pose constraints, which are weighted during the 'bundle adjustment' step in a localization application known as SLAM. The system utilizes inertial data associated with a motion model to predict the pose of the system at the moment a new image is captured. This prediction is then employed to construct an inter-pose constraint, with a technique derived from learning theory selecting the weighting coefficient efficiently. The weighted inter-pose constraint is subsequently integrated into the cost function of the bundle adjustment.
Another significant patent involves a method for processing a three-dimensional image of a tire's surface for inspection purposes. This method determines the three-dimensional profile of the tire surface, identifies characteristic points, and matches them with corresponding points from a reference surface's three-dimensional data. An iterative process seeks a first affine transformation function, which minimizes the distance between transformed characteristic points and matched points on the surface to be inspected. This transformation is then applied to all points of the reference surface to obtain a transformed reference surface.
