Leddar Optical Time-of-flight Sensing Technology: a New Approach to Detection and Ranging
Leddar® optical time-of-flight sensing technology, originally discovered by the National Optics Institute (INO) in Quebec City and developed and commercialized by LeddarTech, is a unique technology in the field of optical sensing. Combining fast, high-resolution analog-to-digital conversion and innovative signal processing, Leddar light processing brings the benefits of timedomain processing to...
متن کاملSupplementary Material: A Light Transport Model for Mitigating Multipath Interference in Time-of-flight Sensors
We perform separation of direct and global components of light transport using the method introduced by Nayar et al. [2]. We illuminate the scene using multiple high frequency patterns and the direct and global components of illumination are obtained from the acquired images using the Nayar method, which is a closed-form, per-pixel solution. We use the DLP Lightcommander projector in near-infra...
متن کاملTime-of-Flight Sensors in Computer Graphics
A growing number of applications depend on accurate and fast 3D scene analysis. Examples are model and lightfield acquisition, collision prevention, mixed reality, and gesture recognition. The estimation of a range map by image analysis or laser scan techniques is still a time-consuming and expensive part of such systems. A lower-priced, fast and robust alternative for distance measurements are...
متن کاملEnhanced single-photon time-of-flight 3D ranging.
We developed a system for acquiring 3D depth-resolved maps by measuring the Time-of-Flight (TOF) of single photons. It is based on a CMOS 32 × 32 array of Single-Photon Avalanche Diodes (SPADs) and 350 ps resolution Time-to-Digital Converters (TDCs) into each pixel, able to provide photon-counting or photon-timing frames every 10 µs. We show how such a system can be used to scan large scenes in...
متن کاملMulti-channel Two-Way Time of Flight Sensor Network Ranging
Two-way time of flight (ToF) ranging is one of the most interesting approaches for localization in wireless sensor networking since previous ToF ranging approaches using commercial off-the-shelf (COTS) devices have achieved good accuracy. The COTS-based approaches were, however, evaluated only in line-of-sight conditions. In this paper, we extend ToF ranging using multiple IEEE 802.15.4 channel...
