Title: The Innovative Mind of Marc Viala
Introduction
Marc Viala is a notable inventor based in Guyancourt, France. He has made significant contributions to the field of technology, particularly in the area of three-dimensional object measurement and camera calibration. With a total of 3 patents to his name, Viala's work showcases his expertise and innovative thinking.
Latest Patents
One of Marc Viala's latest patents is a method for measuring a three-dimensional object or assembly of objects. This system discerns three-dimensional objects in complex environments by identifying their simple contour shapes on images. The geometric characteristics of these objects, along with their positions and orientations, are then measured. The contours are defined by parameters such as length, inclination, and position. The acquired knowledge of the environment is utilized in each new image to refine estimates while introducing new object contours into the model.
Another significant patent is a method for calibrating the initial position and orientation of one or several mobile cameras. This method involves a camera mounted on a mobile support that captures images of a test object formed of at least three marks visible in the camera's field. The analysis of these images provides the initial position and orientation of the camera concerning the test object. As the support moves towards an object, the camera captures images that allow for precise positioning and orientation of the object relative to both the camera and the test object. This method has applications in recording road signs for database composition in network management or onboard navigation systems.
