IMPROVED MULTI-SENSOR FUSION POSITIONING SYSTEM BASED ON GNSS/LIDAR/VISION/IMU WITH SEMI-TIGHT COUPLING AND GRAPH OPTIMIZATION IN GNSS CHALLENGING ENVIRONMENTS

With the development of autonomous driving, precise positioning capabilities are becoming increasingly important.GNSS (Global Navigation Satellite System) is normally utilized for vehicle positioning, but is susceptible to factors such as urban canyons, especially in increasingly urbanized scenario nowadays.The interpretation of relative positionin

The traditional Newton algorithm has heavy calculation burden and low efficiency, its iterations and time will significantly increase when load type pure energy jeans is no longer a constant power.In view of these problems, an improved Newton algorithm for power flow was proposed.The algorithm considers load type to constitute ZIP model with consta

In energy-constrained wireless sensor networks, low energy utilization and unbalanced energy distribution camo iphone se case are seriously affecting the operation of the network.Therefore, efficient and reasonable routing algorithms are needed to achieve higher Quality of Service (QoS).For the Dempster−Shafer (DS) evidence theory, it can fus

Recent studies have shown that traffic safety and efficiency can be substantially improved by vehicle platooning, in which the platoon’ stability is ensured through the exchange of control information among vehicles.So, it is a key issue to share control information efficiently and timely.Proximity-based device-to-device (D2D) communications

The response of Monterey Bay to the Great Tohoku earthquake of 2011 is examined in read more this study.From a practical standpoint, although the resulting tsunami did not cause any damage to the open harbors at Monterey and Moss Landing, it caused extensive damage to boats and infrastructure in Santa Cruz Harbor, which is closed to surrounding wat
