To overcome the inherent bandwidth limitation of non-line-of-sight (NLOS) ultraviolet communication (UVC) channel, a novel space division multiplexing (SDM) framework based on non-coplanar rotation angle is established. The influence SDM structure parameters inter-channel interference (ICI) studied to obtain optimal antenna configuration. And Gaussian approximate distribution (GAD) signal detection model presented, which simplifies calculation Bit error rate (BER) Photon multiplier tube...
Three-dimensional LiDAR systems that capture point cloud data enable the simultaneous acquisition of spatial geometry and multi-wavelength intensity information, thereby paving way for three-dimensional recognition processing. However, due to irregular distribution, low resolution clouds, limited accuracy in complex environments, inherent errors occur classifying segmenting acquired target information. Conversely, two-dimensional visible light images provide real-color enabling distinction...
Point cloud registration based on local descriptors plays a crucial role in 3D computer vision applications. However, existing methods often suffer from limitations such as low accuracy, large memory footprint, and slow speed, particularly when dealing with point clouds low-cost sensors. To overcome these challenges, we propose an efficient descriptor called Binary Weighted Projection-point Height (BWPH) for registration. The core idea behind the BWPH is integration of Gaussian kernel...
To analyze the channel characteristics in omnidirectional reception scenarios for non-line-of-sight ultraviolet (UV) communication, we derive expressions direction distribution based on incident photons at receiver and propose an path loss (PL) model Monte Carlo (MC) method. Furthermore, validate proposed by comparing it with existing MC numerical that traverses all directions. Results indicate average computation time of PL is less than 0.03% traversal while maintaining comparable accuracy....
The Segmented Planar Imaging Detector for Electro-Optical Reconnaissance (SPIDER) is a small volume, lightweight, low energy consumption, and high-resolution system expected to replace traditional large aperture telescopes long-distance detection. In this paper, an improved SPIDER proposed, which uses multimode interference (MMI) coupler instead of orthogonal detector, successfully doubles the space spectrum coverage. We present three-point configuring method configure lenslets, calculate...
More and more industrial production companies apply computer to process control, operation optimization performance evaluation, which significantly increases the amount of data collected. Accurate measurement can provide solid foundation for monitoring, optimization, scheduling, decision analysis. However, is inevitably interfered by errors from multiple processes. This kind interference makes deviate real value cannot meet some conservation laws constraints, make severely deteriorated....

For 3D rigid data matching, local feature description is a fundamental research topic. It remains challenge, however, to balance the shape descriptor between matching accuracy and efficiency. Towards this end, we propose novel representation of surfaces called Binary Weighted Projection-Point Distance (BWPD). A rigorous comparison with state-of-the-art approaches validates superiority feasibility our approach across contexts sensors.
