The error of the height estimates are precisely quantified by comparison with the 3D model height. This paper discusses the development and testing of the inversion of tree height from simulations of ...
Airborne Laser Scanning (ALS) has been established as a valuable tool for the estimation of biophysical canopy variables, such as tree height and vegetation density. However, up to now most approaches...
Airborne Laser Scanning (ALS) has been established as a valuable tool for the estimation of biophysical canopy variables, such as tree height and vegetation density. However, up to now most approache...
A Monte-Carlo ray tracer has been developed from a previous system to simulate a ground based, full waveform laser ranger, such as the Echidna? Overlapping scans have been simulated using a geometric...
Terrestrial geolocalized images are nowadays widely used on the Internet, mainly in urban areas, through immersion services such as Google Street View. On the long run, we seek to enhance the visualiz...
The goal of this article was to compare the contact and immersion ultrasound methods using simulated data. The pursued changes were interrelated with both the axial length of the eye and with partia...
An inherent drawback of SAR imaging of complex 3D structures is the potential layover of more than one scatterer in one resolution cell. Such scatterers can be separated by tomographic processing of...
Utilizing a ray tracing approach based upon Snell’s optical laws and a 4×4 homogeneous coordinate transformation matrix, this study conducts a systematic analysis of the errors induced in the paths of...
In this paper, a numerical analysis of algorithm of optical fiber systems with dimensions much larger than light wavelength has been presented. This algorithm can be used especially in the case of mul...
