Title
(EN) PROJECTION SYSTEM AND METHOD WITH DYNAMIC TARGET GEOMETRY
(FR) PROCÉDÉ ET SYSTÈME DE PROJECTION À GÉOMÉTRIE CIBLE DYNAMIQUE
Abstract
(EN) A projection system and method includes a light source configured to emit a light in response to an image data; a phase light modulator configured to receive the light from the light source and to apply a spatially-varying phase modulation on the light, thereby to steer the light and generate a projection light; and a controller configured to dynamically determine, based on at least one of a user input or a sensor signal, a target geometry of a projection surface on which the projection light is projected, determine, based on the target geometry, a phase configuration for a frame of the image data, and provide a phase control signal to the phase light modulator, the phase control signal configured to cause the phase light modulator to generate the projection light in accordance with the phase configuration for the frame.
(FR) Un procédé et un système de projection comprennent une source de lumière configurée pour émettre une lumière en réponse à des données d'image ; un modulateur de lumière de phase configuré pour recevoir la lumière provenant de la source de lumière et pour appliquer une modulation de phase à variation spatiale sur la lumière, pour ainsi diriger la lumière et générer une lumière de projection ; et un dispositif de commande configuré pour déterminer de manière dynamique, sur la base d'une entrée d'utilisateur et/ou d'un signal de capteur, une géométrie cible d'une surface de projection sur laquelle est projetée la lumière de projection, déterminer, sur la base de la géométrie cible, une configuration de phase pour une trame des données d'image, et fournir un signal de commande de phase au modulateur de lumière de phase, le signal de commande de phase étant configuré pour amener le modulateur de lumière de phase à générer la lumière de projection conformément à la configuration de phase pour la trame.
