| Abstract: | The experimental system of the bridge deflection detection based on laser projection displacement monitoring method is designed, and the basic principle of the system and the algorithm of spot center displacement are introduced. This system consists of the laser transmitting module, laser receiving module, image acquisition and processing module, wireless transmission module and data display module. The experimental results show that the system can detect the vertical deflection of bridge model and meet the needs of experimental teaching. Based on this experimental system, many open and innovative experimental projects can be developed, which can help students to understand the technology of structural health monitoring and improve their innovative thinking and practical ability. |
