Structuring Laser-scanned Trees Using 3d Mathematical Morphology
نویسنده
چکیده
The task addressed in this paper is 3D modelling and reconstruction of (real world) trees on the basis of terrestrial laser scans. To identify the structure of a tree in terms of stem and branches, an algorithm has been designed in 3D voxel space, based on a selection of basic and advanced 2D raster (image) processing algorithms, transferred into the 3D domain. The selection includes filtering, mathematical morphology, skeletonization, connected component labeling and shortest route computation.

Identification and optimization of key process parameters in noncontact laser scanning for reverse engineering
This Extended Technical Note shows that the final accuracy level of reverse engineered surfaces depends on scanning distance and scanning angle of the laser beam, hence it also depends on the morphology of the scanned objects. On scanning strongly curved objects, such as the ones with free form surfaces, the distance and impact angle of the laser beam are changing continuously during the scanni...
متن کاملAccurate Measurement of Cartilage Morphology Using a 3D Laser Scanner
We describe a method to accurately assess articular cartilage morphology using the three-dimensional laser scanning technology. Traditional methods to obtain ground truth for validating the assessment of cartilage morphology from MR images have relied on water displacement, anatomical sections obtained with a high precision band saw, stereophotogrammetry, manual segmentation, and phantoms of kn...
