Data extraction from dense 3-D surface models

چکیده
Stereo-photogrammetry involves the use of pairs of cameras to extend standard photographic methods by recovering depth information through triangulation (Ayoub et al. 1998). The resulting data consist of a point-cloud of threedimensional observations, providing a digital representation of the surface of the object of interest. The number of observations can typically be many thousands, providing a rich source of information on object shape. This can be represented efficiently as an irregular triangular mesh, in Virtual Reality Modelling Language form.

Supercritical Fluid Extraction of Carotenoid from Microalgae with Projected Thermodynamic Models (RESEARCH NOTE)
In this study, two thermodynamic models (regular solution theory and equation of state) were applied to obtain carotenoid solubility in the supercritical carbon dioxide solvent. Theoretical data obtained from the models were compared with the experimental data extracted from a published paper. The use of equation of state as an empirical correlation for collating and predicting liquidliquid and...
متن کاملComprehensive Analysis of Dense Point Cloud Filtering Algorithm for Eliminating Non-Ground Features
Point cloud and LiDAR Filtering is removing non-ground features from digital surface model (DSM) and reaching the bare earth and DTM extraction. Various methods have been proposed by different researchers to distinguish between ground and non- ground in points cloud and LiDAR data. Most fully automated methods have a common disadvantage, and they are only effective for a particular type of surf...

Ultrasonic technology and response surface methodology (RSM) wereused for optimization of extraction of condensed tannins from the leaf, acron, gland and gall of oak. Three independent variables such as solvent percentage (%), temperature (°C) and time (min) were studied. Effect of methanol concentration was found to be significant on all responses. Optimal ultrasonicassisted extraction (UAE) c...

متن کاملIntegrated Surface, Curve and Junction Inference from Sparse 3-D Data Sets
We are interested in descriptionsof 3-D data sets, as obtained from stereoor a 3-D digitizer. We therefore consideras input a sparse set of points, possibly associated with certain orientation information. In this paper, we address the problem of inferring integrated high-level descriptions such as surfaces, curves, and junctions from a sparse point set. While the method described in [5], [6] p...
