基于超声波辅助测距的可见光室内定位系统
Visible light indoor positioning system based on ultrasonic aided ranging
摘要
Abstract
The mutual interference between LED transmitting module and receiving module delay synchro-nization problems seriously affect the visible light indoor positioning precision of the system, this paper se-lects the ultrasonic sensor for sensing device, designs a visible light indoor positioning method. The method uses the optical signal to complete the synchronization, ultrasonic module auxiliary ranging, and uses the con-figured light location TDOA algorithm to measure the position coordinates of the sensor. After error analysis and multiple debugging, the sensor can correctly distinguish the region and coordinates of its location, and control the error in the request scope, the performance is good.关键词
