Title (EN) DYNAMIC VISION SENSOR ARCHITECTURE
(FR) ARCHITECTURE DE CAPTEUR DE VISION DYNAMIQUE
Abstract:
(EN) A dynamic vision sensor (DVS) or change detection sensor reacts to changes in light intensity and in this way monitors how a scene changes. This disclosure covers both single pixel and array architectures. The DVS may contain one pixel or 2- dimensional or 1-dimensional array of pixels. The change of intensities registered by pixels are compared, and pixel addresses where the change is positive or negative are recorded and processed. Analyzing frames based on just three values for pixels, increase, decrease or unchanged, the proposed DVS can process visual information much faster than traditional computer vision systems, which correlate multi-bit color or gray level pixel values between successive frames.
(FR) Selon l'invention, un capteur de détection de vision dynamique (DVS) ou un capteur de détection de changement réagit aux changements d'intensité lumineuse et surveille ainsi la manière dont une scène change. La présente invention couvre à la fois des architectures de pixel unique et en matrice. Le DVS peut contenir un pixel ou une matrice bidimensionnelle ou unidimensionnelle de pixels. Le changement d'intensités enregistrées par les pixels est comparé, et des adresses de pixels où le changement est positif ou négatif sont enregistrées et traitées. Par l'analyse de trames sur la base de trois valeurs simplement pour des pixels (qu'elles soient augmentées, diminuées ou inchangées) le DVS proposé peut traiter des informations visuelles beaucoup plus rapidement que les systèmes classiques de vision artificielle, qui mettent en corrélation des valeurs de pixel de couleur ou de niveau de gris à plusieurs bits entre des trames successives.
