Appel\u00e9 \u00b5WAI (micro-WAY) et de la taille d’une pi\u00e8ce de 1 \u20ac, l’imageur comprend un capteur d’image, un ASIC et une batterie. Le module dispose d’un pipeline algorithmique optimis\u00e9, dans lequel les r\u00e9sultats d’une s\u00e9quence d’algorithmes \u00e9l\u00e9mentaires sont utilis\u00e9s pour fournir des modes de r\u00e9veil \u00e0 faible puissance et une mise en \u0153uvre compacte du silicium pour r\u00e9duire les co\u00fbts.<\/p>\n

Le capteur d’image intelligent dispose de l’exposition automatique selon les conditions d’\u00e9clairage et une plage dynamique de 88 dB, ainsi qu’une d\u00e9tection de mouvement et une extraction de caract\u00e9ristiques et une reconnaissance d’objets bas\u00e9e sur l’IA.<\/p>\n

Cela permet \u00e0 l’imageur d’ouvrir des syst\u00e8mes avec seulement quelques pJ \/ pixel \/ frame. Une impl\u00e9mentation typique de cam\u00e9ra discr\u00e8te plus processeur n\u00e9cessiterait environ 10 000 fois plus d’\u00e9nergie de plus que \u00b5WAI, a d\u00e9clar\u00e9 le Leti.<\/p>\n

\u00ab\u00a0Le moteur de reconnaissance est optimis\u00e9 pour reconna\u00eetre les visages lorsqu’un mouvement est d\u00e9tect\u00e9. L’\u00e9quipe du CEA-Leti travaille main dans la main avec STMicroelectronics pour d\u00e9velopper des produits d’imagerie intelligente sp\u00e9cifiques alors que nous envisageons d’\u00e9tendre la technologie \u00e0 d’autres cas d’utilisation\u00a0\u00bb, a d\u00e9clar\u00e9 Antoine Dupret, Responsable des partenariats industriels du CEA-Leti<\/p>\n

L’unit\u00e9 consomme 3 \u00e0 6 microwatts et devrait atteindre une dur\u00e9e de vie de la pile CR1025 de cinq ans, toujours allum\u00e9.<\/p>\n

Les applications et les fonctions comprennent la commutation automatique et l’identification des visages dans les appareils mobiles, la commutation intelligente sans contact des appareils m\u00e9nagers et des appareils de sport et de divertissement dans les maisons intelligentes. \u00b5WAI fournit \u00e9galement la reconnaissance faciale, le comptage des personnes, le d\u00e9clenchement d’alarme dans les b\u00e2timents intelligents, la d\u00e9tection de la situation \u00e0 l’int\u00e9rieur du v\u00e9hicule, l’identification du conducteur, la d\u00e9tection de la situation de stationnement et un syst\u00e8me de d\u00e9verrouillage intelligent dans les automobiles.<\/p>\n
