[0017] The present invention is used to provide a building structural displacement measurement method based on a dynamic visual sensor DVS, in order to make the technical solutions and effects of the present invention, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0018] like figure 1 As shown, a building structural displacement measurement method based on the dynamic visual sensor DVS is designed, including four stages, which are segments in the target tracking phase, the pretreatment phase, the edge detection and the positioning phase, and the structural bit shifting magnetic curve generating stage. The pretreatment phase includes the event stream generating picture sequence and image denoising, edge detection and positioning stages including the edge detection and target circle of the target image texture after denoising, and the structural displacement curve generating stage is mainly based on...
