Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A 3D imager is presented capable of capturing the depth map of an arbitrary scene. Depth is measured by computing the time-of-flight of a ray of light as it leaves the source and is reflected by the objects in the scene. The round-trip time is converted to ...
A solid-state imager fabricated in CMOS technology is presented for depth information capture of arbitrary 3D objects with millimeter resolution. The system is based on an array of 32x32 pixels that independently measure the time-of-flight of a ray of ligh ...
A 3D imager is presented capable of computing the depth map as well as the intensity scale of a given scene. The heart of the system is a two-dimensional array of single photon avalanche diodes fabricated in standard CMOS technology. The diodes exhibit low ...
Nowadays, 3D multimedia applications have grown rapidly in number and consist of complex systems (e.g. 3D graphical processing or games) that process extensive amounts of data to create 3D images and results. This produces highcost and high-power consumpti ...
An 8x4 avalanche diode array in a 0.8μm CMOS process uses single photon counting for time-of-light range finding with 100ps 40mW decollimated laser pulses. An accuracy of 618μm is achieved from 15cm to 1m with 10e4 pulses. ...
