Journal ArticleDOI
A Mixed Deep Recurrent Neural Network for MEMS Gyroscope Noise Suppressing
TL;DR: A deep long short term memory recurrent neural network and a deep gated recurrent unit–recurrent neural network were combined together to construct a two-layer recurrent neuralnetwork for noise modeling of a micromechanics system gyroscope, and results supported a positive conclusion on the performance of designed method.
Journal ArticleDOI
A practical method utilizing multi-spectral LiDAR to aid points cloud matching in SLAM
Changhui Jiang,Changhui Jiang,Yuwei Chen,Yuwei Chen,Wenxin Tian,Ziyi Feng,Ziyi Feng,Wei Li,Chunchen Zhou,Hui Shao,Hui Shao,Eetu Puttonen,Juha Hyyppä +12 more
TL;DR: A Hyperspectral LiDAR (HSL)-based-intensity calibration-free method to aid point cloud matching in SLAM that enhanced the heading angle estimation by 72%, and showed an average 25.5% improvement in a featureless spatial testing environment.
Journal ArticleDOI
Analyzing the Angle Effect of Leaf Reflectance Measured by Indoor Hyperspectral Light Detection and Ranging (LiDAR)
Peilun Hu,Huaguo Huang,Yuwei Chen,Jianbo Qi,Wei Li,Changhui Jiang,Haohao Wu,Wenxin Tian,Juha Hyyppä +8 more
TL;DR: The angle effect of leaf reflectance from indoor HSL measurements of individual leaves from four typical tree species in Beijing is studied and an empirical model is established to correct the influence of angle effect on the reflectance of the leaf for HSL applications.
Journal ArticleDOI
Preliminary verification of hyperspectral LiDAR covering VIS-NIR-SWIR used for objects classification
Haibin Sun,Zhien Wang,Yuwei Chen,Wenxin Tian,Wen Jing He,Haohao Wu,Huijing Zhang,Lingli Tang,Changhui Jiang,Jianxin Jia,Zhiyong Duan,Hui Zhou,Eetu Puttonen,Juha Hyyppä +13 more
TL;DR: In this article , an eight-channel HSL prototype covering visible to near-infrared and even short-wavelength infrared (VIS-NIR-SWIR, 450-1460 nm) based on a Super-continuum (SC) laser was proposed and tested.
Journal ArticleDOI
A practical method for employing multi-spectral LiDAR intensities in points cloud classification
Changhui Jiang,Yuwei Chen,Yuwei Chen,Wenxin Tian,Haohao Wu,Wei Li,Hui Zhou,Hui Shao,Shaojing Song,Eetu Puttonen,Juha Hyyppä +10 more
TL;DR: In this article, LiDAR intensity is associated with the target surface material, which could help the points cloud classification, however, the intensity is also associated with light detection and ranging (LiDAR) intensity.
