Research on a 3D Point Cloud Map Learning Algorithm Based on Point Normal Constraints

Autor: Zhao Fang, Youyu Liu, Lijin Xu, Mahamudul Hasan Shahed, Liping Shi

Publikováno v: Sensors, Vol 24, Iss 19, p 6185 (2024)

Laser point clouds are commonly affected by Gaussian and Laplace noise, resulting in decreased accuracy in subsequent surface reconstruction and visualization processes. However, existing point cloud denoising algorithms often overlook the local cons

Simple coarse sensing to achieve high precision From attractive region in environment to constrained region in environment

Autor: Hong Qiao, Chao Ma, Rui Li, Xiaoqing Li, Ziyu Chen, Wei Wu, Lijin Xu

Publikováno v: Systems Science & Control Engineering, Vol 5, Iss 1, Pp 16-24 (2017)

As a fundamental yet urgent issue, achieving high-precision robotic manipulation is becoming an active research area. Unfortunately, it is practically impossible to obtain an unlimited increase in sensor accuracy. In contrast, sensor-less manipulatio

Enhancement of Lysozyme Crystallization Using DNA as a Polymeric Additive

Autor: Bo Zhang, Yao Wang, Shiki Thi, Vincent Toong, Ping Luo, Shilong Fan, Lijin Xu, Zhongqiang Yang, Jerry Y. Y. Heng

Publikováno v: Crystals, Vol 9, Iss 4, p 186 (2019)

This study reports the first experimental evidence of using DNA as a polymeric additive to enhance protein crystallization. Using three kinds of DNA with different molecular weights—calf DNA, salmon DNA, and herring DNA—this study showed an impro
