Volume Measurement Using a Laser Scanner
نویسندگان
چکیده
This article discusses ways of measuring accuracy of a laser range finder (LRF) using a specially designed calibration cube (with 3D calibration marks) in the context of a particular application (i.e., measuring volumes). We also compare (by means of experiments) two alternative volume estimation methods.

متن کاملOcclusion Area as Suitable Guidance for Terrestrial Laser Scanner Localization
Terrestrial Laser Scanner (TLS) technology, have altered quickly data acquisition for map production in surveying. In many cases, it is impossible to complete surveying of the desired area without TLS displacement in one station to another. Occlusion is innate in data acquisition, with this type of device. To solve this problem, TLS devices should be placed in different locations and scanning o...
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...
متن کاملVoxel Approach to Landscape Modelling
In this paper, we present a method for 3D volumetric reconstruction of landscape from airborne laser scanner data. The method applies a voxel model, where volume is divided to sub-volume particles, voxels, associated with a scalar or vector value. In the presented study the voxel model is generated from airborne laser scanner data, which enables measurement of large areas. Laser scanning provid...
متن کاملA Voxel-based Technique to Estimate the Volume of Trees from Terrestrial Laser Scanner Data
The precise determination of the volume of standing trees is very important for ecological and economical considerations in forestry. If terrestrial laser scanner data are available, a simple approach for volume determination is given by allocating points into a voxel structure and subsequently counting the filled voxels. Generally, this method will overestimate the volume. The paper presents a...
