The high point densities obtained by today’s airborne laser scanners enable the extraction of various features that are traditionally mapped by photogrammetry or land surveying. While significant pr...
Airborne laser scanning (ALS) based height and intensity information was exploited for the vertical stratification of vegetation layers in a multilayered Mediterranean ecosystem. A new methodol...
Terrestrial methodologies, as high resolution laser scanning and digital photogrammetry, are used in many applications in the field of architectural and cultural heritage surveys: they are character...
This paper describes the first phase of a three year PhD research project which aims at extracting road and roadside information accurately and robustly from airborne sensor data and assessing its sui...
Laser footprint size and beam divergence angle tuning was found to affect LiDAR data accuracy and measurement precision because of beam axis shifting. The laser beam divergence angle is generally tuna...
Although some mature manufactures of airborne laser system (ALS) have been published for some years, however, in china, the development of ALS just is on the starting step. Shanghai Institute of Techn...
Data storage capacity and high processing speed available today has made it possible to digitally sample and store the entire reflected waveform of Small-Footprint Airborne Lidar (light detection and ...
Small-footprint airborne laser scanners (ALS) are lidar instruments originally developed for topographic mapping. In recent years ALS sensors are increasingly used also in other applications (forest m...
For tasks such as the generation of realistic visualizations from pedestrian viewpoints in virtual reality and multimedia applications, urban models extracted from airborne data are too coarse and t...
在这篇论文中,作者利用双电磁诱导透明窗口这一原子相干控制手段,对相互伴随的四波混频和荧光信号进行二次裁剪,获得了线宽仅为10MHz左右的超窄荧光信号,并深入研究了其调控方法,该研究在超窄线宽激光,精密测量与量子相关方面有着重要的潜在应用价值。张彦鹏教授领导的科研团队近几年来通过与阿肯色大学肖敏教授的合作,在多波混频相干控制、原子与分子量子调控等方面取得了一系列突破性进展。 多波混频是一种重要的非...
Mobile laser scanning systems are becoming an increasingly popular means to obtain 3D coverage on a large scale. To perform the mapping, the exact position of the vehicle must be known throughout the ...
This paper deals with the referencing of single images taken independently from the laser scanner (camera not mounted on the scanner) to a laser scanner point cloud of the same scene. The single ima...
In this paper, we present a multimedia scene representation application implementing MPEG4-Part 20 Lightweight Application Scene Representation standard (LASeR). In an interactive multimedia scene, we...
