Non-contact spatial displacement measurement device

Abstract

The invention discloses a non-contact spatial displacement measurement device. The non-contact spatial displacement measurement device comprises a laser range finder arranged on the reference point, an imaging transmitting plate arranged on the monitoring point, an image collection device arranged on the side, with the back to the laser range finder, of the imaging transmitting plate, a drive module and a control module. The imaging transmitting plate is used for receiving light emitted by the laser range finder and forming light spots. The image collection device is used for collecting the light spots formed on the imaging transmitting plate and connected with the drive module, and the drive module is connected with the control module. The non-contact spatial displacement measurement device is large in measuring range, high in measurement accuracy, small in power consumption and capable of measuring prostration and hypsokinesis from front to back and forward and reverse rotation deformation, relative to a laser device, of a position sensor, solves the problems in the prior art and can be widely used for monitoring deformation of engineering buildings under the condition of geological disasters, and the measuring range is convenient to adjust.

Description

technical field [0001] The invention relates to a space displacement measurement device, in particular to a non-contact space displacement measurement device for monitoring engineering building deformation under geological disaster conditions. Background technique [0002] There are many types of existing deformation monitoring, mainly using professional instruments and sensors to continuously observe the deformation phenomenon of deformable bodies, analyze the deformation behavior of deformable bodies, and predict the development trend of deformable body deformation. In engineering surveying, the most representative deformation bodies are tunnels, bridges, highways, dams, slopes, subways, high-rise buildings, etc. The content of deformation monitoring is determined according to the nature of the deformable body and the ground conditions. It mainly observes the horizontal displacement, vertical displacement of the measured body and the distance change between the fixed point...
