Recovering Parametric Scenes from Very Few Time-of-Flight Pixels
Carter Sifferman, Yiquan Li, Yiming Li +4
We aim to recover the geometry of 3D parametric scenes using very few depth measurements from low-cost, commercially available time-of-flight sensors. These sensors offer very low…
Efficient Detection of Objects Near a Robot Manipulator via Miniature Time-of-Flight Sensors
Carter Sifferman, Mohit Gupta, Michael Gleicher
We provide a method for detecting and localizing objects near a robot arm using arm-mounted miniature time-of-flight sensors. A key challenge when using arm-mounted sensors is diff…
Using a Distance Sensor to Detect Deviations in a Planar Surface
Carter Sifferman, William Sun, Mohit Gupta +1
We investigate methods for determining if a planar surface contains geometric deviations (e.g., protrusions, objects, divots, or cliffs) using only an instantaneous measurement fro…
Towards 3D Vision with Low-Cost Single-Photon Cameras
Fangzhou Mu, Carter Sifferman, Sacha Jungerman +5
We present a method for reconstructing 3D shape of arbitrary Lambertian objects based on measurements by miniature, energy-efficient, low-cost single-photon cameras. These cameras,…
IKLink: End-Effector Trajectory Tracking with Minimal Reconfigurations
Yeping Wang, Carter Sifferman, Michael Gleicher
Many applications require a robot to accurately track reference end-effector trajectories. Certain trajectories may not be tracked as single, continuous paths due to the robot's ki…
Unlocking the Performance of Proximity Sensors by Utilizing Transient Histograms
Carter Sifferman, Yeping Wang, Mohit Gupta +1
We provide methods which recover planar scene geometry by utilizing the transient histograms captured by a class of close-range time-of-flight (ToF) distance sensor. A transient hi…
A Review of Scene Representations for Robot Manipulators
Carter Sifferman
For a robot to act intelligently, it needs to sense the world around it. Increasingly, robots build an internal representation of the world from sensor readings. This representatio…
