Recovering Three-Dimensional Shape Around a Corner Using Ultrafast Time-of-Flight Imaging
Explore a novel method for recovering hidden 3D objects around corners using ultrafast time-of-flight imaging. The research discusses the reconstruction algorithm, experimental setup, and overall ratings with pros and cons. Discover how each point on the hidden surface contributes to the image through hyperboloids.

Recovering Three-dimensional Shape Around a Corner using Ultrafast Time-of-Flight Imaging Shiyu Dong, Sida Wang 03/17/2016
Introduction How to see around corners?
Reconstruction Algorithm Each point on the hidden surface S will contribute a hyperboloid to the image
Reconstruction (b)Data acquisition (c)Backprojection (d)Filtering (e)Depth map (f)Confidence map (g,h,i) 3D
Overall Rating: 1 Discussion(pros & cons) Pros: Novel method to solve the problem of recovering hidden 3D object Various application Robust for Lambertian surfaces and near-Lambertian surfaces Cons: Assumption: without inter-reflection within the object
