[0002] In the field of building structure health monitoring and safety assessment, it is crucial to accurately measure the deformation and displacement of houses, bridges, high-rise buildings and other infrastructure. Traditional measurement methods include using level, total station and GPS equipment for monitoring, but these methods are usually time-consuming, require professional operation, and are difficult to achieve continuous real-time monitoring. With the advancement of technology, laser scanning technology has gradually become an important tool for deformation monitoring due to its advantages of high precision, high speed and non-contact measurement.
