【摘要】 室内空间越来越庞大、越来越复杂,对于停车场、商场、机场等场所的定位和导引的需求日趋强烈。同时,智能制造、机器人、无人医疗护理等领域也需要计算机能在室内识别特定目标的位置。因此,室内定位是这些技术的关键。以下内容基于射频信号强度与超声波原理,提出了一套较为完整的室内定位方法,并设计构建了实验系统。将定位目标分别处于静止、移动状态下进行了定位实验,获得了实验结果。实验结果表明,基于射频信号强度与超声波测距的室内目标定位方法是可行的,具有较高的应用价值。更多还原

【Abstract】 Indoor space is becoming more and more large and complex, and the demand for location and guidance of parking lots, shopping malls, airports and other places is increasingly strong. At the same time, intelligent manufacturing, robotics, unmanned medical care and other fields also require computers to identify specific targets in the room. Therefore, indoor positioning is the key to these technologies. Based on the principle of RF signal intensity and ultrasonic wave, a relatively complete indoor positioning method is proposed, and an experimental system is designed and constructed. Localization experiments were carried out under stationary and moving targets respectively, and the experimental results were obtained. The experimental results show that the indoor target location method based on RF signal intensity and ultrasonic ranging is feasible and of high application value.更多还原
