Introduction: Myopia presents a significant challenge to the ophthalmologist as myopic discs are often large, tilted, with deep cups and have a thinner neuroretinal rim all of which may mimic glaucomatous optic nerve head changes causing an error in diagn... see more

Laser scanning is a new measurement technique through which can be recorded, fully automatic with high precision and speed. In documenting of existing buildings and facilities, knowing the geometry of the object is the most important. Old university build... see more

Given that, in the recent years, the technique and technology has an impressive development and the topographic measurement equipment became increasingly sophisticated, the 3D laser scanning technology is the latest technology in the field, revolutionizin... see more

In this study, we present the results of an analysis of Terrestrial Laser Scanning (TLS) datasets, referred to multi-temporal (2013-2015) acquisition, aimed at evaluating volumetric changes and average retreat rates of the Coroglio tuff cliff, located in ... see more

Neste trabalho é apresentado um método automático para registro de pares de nuvens de pontos derivados do sistema LASER scanning terrestre usando superfícies planas. Primeiramente, as superfícies planas são detectadas através do algoritmo RANSAC e, poster... see more

Multi-temporal airborne laser scanning (ALS) surveys have become a prime consideration for detecting landslide movements and evaluating landslide risk in mountain areas. The minimum elevation change (or detectability) that can be detected by repeated ALS ... see more

We outline an approach combining airborne laser scanning (ALS) and imaging spectroscopy (IS) to quantify and assess patterns of tree density (TD) and forest productivity (FP) in a protected heterogeneous alpine forest in the Swiss National Park (SNP). We ... see more

In recent years, small-footprint full-waveform airborne laser scanning has become readily available and established for vegetation studies in the fields of forestry, agriculture and urban studies. Independent of the field of application and the derived fi... see more

Diameter at breast height has been estimated from mobile laser scanning using a new set of methods. A 2D laser scanner was mounted facing forward, tilted nine degrees downwards, on a car. The trajectory was recorded using inertial navigation and visual SL... see more
