The flight environment of unmanned aerial vehicles faces various challenges. To effectively navigate and perform tasks, they need to effectively integrate multiple sensors. This study applies the adaptive weighted average method, combined with data from global positioning system, inertial measurement unit, three-dimensional optical detection and ranging, and uses linear Kalman filtering to smooth the merged velocity data. High-order B-spline curves for route planning and applying flight constraint formulas to better adapt are used to the dynamics of unmanned aerial vehicles. The research results indicated that the improved adaptive weighting algorithm had high comprehensive performance for multi-sensor data fusion, with the highest accuracy, robustness, real-time performance, and consistency of 94.2%, 93.7%, 100%, and 95.6%, respectively. The flight path lengths planned by the A & lowast;algorithm and higher-order B-spline curve were 15.7 and 16.3 m, respectively, and the flight time was 8.2 and 7.1 s, respectively. The flight path planned by higher-order B-spline curve was further away from obstacles. The use of adaptive weighted fusion and linear Kalman filtering facilitates the fusion of multi-sensor data, and autonomous flight routes planned using high-order B-spline curves can also meet the needs of unmanned aerial vehicle flight in complex flight environments.

During the epidemic, a large number of patients flooded into hospitals, leading to a shortage of hospital resources and placing greater work pressure and infection risks on medical staff. Automated Guided Vehicles (AGVs) offer a promising solution for indoor inspection, alleviating the shortage of healthcare personnel and preventing the spread of viruses to the outside. This paper focuses on utilizing AGVs to collect patient vital sign monitoring data, effectively mitigating the shortage of medical personnel and avoiding virus transmission. During the process of finding the optimal path by AGVs, encountering zero resultant force hindered path exploration and led to the occurrence of local minima. This paper proposes a hybrid differential evolution-based artificial potential field algorithm (HDE-APF), where the differential evolution-based artificial potential field algorithm(DE-APF) introduces an adaptive weighting algorithm and simplifies repulsive forces during the optimization process to address issues such as unreachable targets and local minima.
