Production of DTM quality by TLS data

Automatic DTM Generation from Three-Line-Scanner (TLS) Images

This paper presents a matching procedure for automatic DSM generation from the Three-Line-Scanner (TLS) raw images. It can provide dense, precise and reliable results. The proposed method combines matching procedures based on grid point matching and feature point matching. Modified Multiphoto Geometrically Constrained Matching (MPGC) and Geometrically Constrained Multipoint Matching (GCMM) are ...

the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.

Filtering of Tls Point Clouds for the Generation of Dtm in Salt-marsh Areas

Marshes are ubiquitous landforms in estuaries and lagoons, where important hydrological, morphological and ecological processes take place. These areas attenuate sea action on the coast and act as sediment trapping zones. Due to their ecosystem functions and effects on coastal stabilization, marshes are crucial structures in tidal environments, both biologically and geomorphologically, and fund...

modeling loss data by phase-type distribution

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
