Indoor scene reconstruction is important for robot positioning and navigation in scenario reconstruction, especially in constructing a semantic map.In previous research, RGB-D cameras have been utilized to obtain a semantic map.However, because of indoor objects and depth sensors, the accuracy and precision of the depth values could be improved, wh
Fiber-coupled differential phase-shift keying (DPSK) modulation is potentially an effective approach for further high-speed satellite lasercom, due to the high detection Floral Art sensitivity, low linewidth requirements, and uncalled-for complex phase-locked loop techniques.Nevertheless, the phase distortion caused by atmospheric turbulence will d
This article is devoted to solving the problem of noise and vibration in complex pipelines of hydromechanical systems.In the study, the first ten frequencies of Minnesota natural oscillations are calculated for sections of the pipeline system filled with water with outer diameters of 60, 70, 102 mm and various thicknesses of the pipeline wall.It is
On June 18, 2018, under the influence of heavy rainfall, a debris flow disaster broke out in Xigou village of the Three Gorges Reservoir Area in Chongqing, causing some residential houses to be buried along with great economic losses.The on-site investigation found many loose solid material sources in the debris flow gully.Under the conditions of h
