GPR Virtual Guidance System for Subsurface 3D Imaging

Advanced Gpr System for High-performance Tomographic Subsurface Imaging

In this paper, the research prototype of a high-performance GPR imaging system is presented. The system is equipped with the capability of synthetic-aperture scan, stepfrequency FMCW illumination, and high-resolution tomographic image reconstruction.

GPR based soil electromagnetic parameters determination for subsurface imaging

The problem of estimating the dielectric permittivity and the electric conductivity of the soil starting from GPR measurements is addressed. A new estimation procedure is proposed and checked against synthetic data generated by a FDTD forward solver. A two-dimensional geometry and a two-layered background medium are considered.

Dynamic Scene Reconstruction for 3D Virtual Guidance

In this paper a system is presented able to reproduce the actions of multiple moving objects into a 3D model. A multi-camera system is used for automatically detect, track and classify the objects. Data fusion from multiple sensors allows to get a more precise estimation of the position of detected moving objects and to solve occlusions problem. These data are then used to automatically place a...

Hydraulic conductivity measurment for subsurface drainage system

A Subsurface Acoustic Imaging System

of soil were evaluated. The current study will describe the imaging system and present preliminary images produced from data collected from a soil phantom. W e have built the imaging system, which incorporates a single element source transducer and a receiver array, both obtained from the Applied Research Laboratory at Pennsylvania State University. The source and receiver array are moved toget...
