At the Poggio Baldi natural laboratory we perform three-dimensional change detection of the sequentially acquired 3D point cloud in order to identify unstable zones along the upper scarp and to quantify the amount of rock fall volumes. Additionally, by means of 3D point clouds discontinuity sets have been extracted to better understand the rock mass structure.
Multi-temporal 3D Change Detection
Terrestrial SAR Interferometry
T-InSAR monitoring is implemented at the Poggio Baldi Lab to detect and track millimetric displacements of the debris talus at the toe of the main rock scarp.
PhotoMonitoring
At the Poggio Baldi natural laboratory we are experimenting new processing techniques of digital images based on quantitative analysis for detecting and monitoring rockfalls.

Gigapixel Imagery
Gigapixel identifies a digital image achieved by stitching technique, i.e. by merging several images acquired from the same position covering the whole view of interest. These digital images can be composed of billions of pixels or more. The GigaPan system allows the sequential acquisition of hundreds of partially overlapped images. This result is achieved thanks to a robotic head mounted on a tripod that allows the rotation of the camera around a point of no parallax. This technique saw its greatest use in geoscience as a way for the representation and interpretation of high-resolution scenarios.
Acoustic Monitoring
Acoustic signal measurements are carried out on the sound level meter CUBE paired with an outdoor microphone unit produced by 01dB part of ACOEM Group. The 01dB CUBE can measure one-third octave band noise levels down to 6.3 Hz together with recording audio sample up to 180 dB at set intervals.
At the Poggio Baldi natural laboratory we record instantaneous sound pressure levels and spectra in order to identify and characterize rock falls phenomena.
Weather Station
Weather parameters are collected every 10 minutes through a station of type Vantage Pro from Davis Instruments.
Live data from the Poggio Baldi station can be visualised here.
