Integrated Georeferencing of LiDAR and Camera Data Acquired from a Moving Platform [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014 This paper presents an approach for modeling the trajectory of a moving platform equipped with a laser scanner and a camera. In most cases, GNSS and INS is used to determine the orientation of the platform, but sometimes it is impossible to use GNSS ...

Localisation and Mapping Using a Laser Range Finder: A Goal-Seeking Approach [PDF]
, 2009 In this paper we examine the problem of localisation and mapping of an unknown environment using data from a laser range finder. In order to support our method we detect landmarks in the environment using the same laser finder.

Comparing Three Different Ground Based Laser Scanning Methods for Tree Stem Detection
Remote Sensing, 2018 A forest inventory is often carried out using airborne laser data combined with ground measured reference data. Traditionally, the ground reference data have been collected manually with a caliper combined with land surveying equipment.

Estimation of tree lists from airborne laser scanning by combining single-tree and area-based methods [PDF]
, 2010 Individual tree crown segmentation from airborne laser scanning (ALS) data often fails to detect all trees depending on the forest structure. This paper presents a new method to produce tree lists consistent with unbiased estimates at area level.
