VIO-Aided Structure from Motion Under Challenging Environments
Zijie Jiang, Hajime Taira, Naoyuki Miyashita +1
In this paper, we present a robust and efficient Structure from Motion pipeline for accurate 3D reconstruction under challenging environments by leveraging the camera pose informat…
3D Pipe Network Reconstruction Based on Structure from Motion with Incremental Conic Shape Detection and Cylindrical Constraint
Sho kagami, Hajime Taira, Naoyuki Miyashita +2
Pipe inspection is a critical task for many industries and infrastructure of a city. The 3D information of a pipe can be used for revealing the deformation of the pipe surface and…
Single-cycle THz pulses with amplitudes exceeding 1 MV/cm generated by optical rectification in LiNbO3
H. Hirori, A. Doi, F. Blanchard +1
Using the tilted-pulse-intensity-front scheme, we generate single-cycle terahertz (THz) pulses by optical rectification of femtosecond laser pulses in LiNbO3. In the THz generation…
High Quality Factor Silicon Cantilever Driven by PZT Actuator for Resonant Based Mass Detection
Jian Lu, T. Ikehara, Yi Zhang +3
A high quality factor (Q-factor) piezoelectric lead zirconat titanate (PZT) actuated single crystal silicon cantilever was proposed in this paper for resonant based ultra-sensitive…
