Workspace Measurement Positioning System Based on Optical Scanning and Wireless Sensor Network
A novel workspace measurement positioning system based on optical scanning and wireless sensor network is presented in this paper. Coordinate measurement principle through angle intersection is detailed discussed. According to analysis of system requirement, a Zigbee wireless sensor network is designed for data transmission; routing algorithm and flowchart of nodes software are also given. A platform consists of two planar laser transmitter and optical receivers is set up for verification. Experiments result demonstrates that the accuracy of new angle measurement method is better than 1mm.
