基于D-S证据理论的超声波测距模型的设计

摘要

在分析超声波传感器的测量特性和信息不确定性的基础上,提出了一种新的超声波传感器模型,该模型利用D-S证据理论来计算超声波传感器扇形范围之内的栅格信息的可信度,能准确描述出超声波传感器测量范围之内的障碍物位置.通过仿真验证了该方法的有效性和实用性.%Based on the analysis of the measurement characteristics and uncertainty of ultrasonic sensor, a novel ultrasonic sensor model is introduced. In this model, the reliability of grid information in the sector region of ultrasonic sensor can be calculated using the D-S evidence theory, the obstacle position can be detected in the range of ultrasonic sensor. The simulation results indicate that the model is efficiency and applicability.
