Title
(EN) SYSTEM AND METHOD TO DETECT ARTICULATE BODY POSE
(FR) SYSTÈME ET PROCÉDÉ PERMETTANT DE DÉTECTER UNE POSE DE CORPS ARTICULÉ
Abstract
(EN)
A system for detecting an articulate body pose from an imagery content includes an imaging module for capturing the imagery content, and a processor that is operable to obtain a top-down view of the imagery content, and process the top-down view to detect the articulate body pose using a machine learning algorithm, wherein the articulate body pose includes a plurality of joints. The processing includes creating a part confidence map corresponding to each joint of the articulate body pose, generating a heatmap by projecting the part confidence map on the top-down view of the imagery content, creating a part affinity map corresponding to each body part, generating a vector map by projecting the part affinity map on the top-down view of the imagery content, and generating a body-framework corresponding to the articulate body pose, using the heatmap and the vector map.

L'invention concerne un système destiné à détecter une pose de corps articulé à partir d'un contenu d'imagerie qui comprend un module d'imagerie pour capturer le contenu d'imagerie, et un processeur qui permet d'obtenir une vue de dessus du contenu d'imagerie, et de traiter la vue de dessus pour détecter la pose de corps articulé à l'aide d'un algorithme d'apprentissage automatique, la pose de corps articulé comprenant une pluralité de joints. Le traitement comprend la création d'une carte de confiance de partie correspondant à chaque articulation de la pose de corps articulé, la génération d'une carte thermique par projection de la carte de confiance de partie sur la vue de dessus du contenu d'imagerie, la création d'une carte d'affinité de partie correspondant à chaque partie de corps, la génération d'une carte vectorielle par projection de la carte d'affinité de partie sur la vue de dessus du contenu d'imagerie, et la génération d'un cadre de corps correspondant à la pose de corps articulé, à l'aide de la carte thermique et de la carte vectorielle.
