Real-time monitoring method for deviation rectification and reinforcement of inclined inscription cultural relics based on CNN

Abstract

The invention discloses a real-time monitoring method for deviation rectification and reinforcement of inclined stele cultural relics based on CNN. The real-time monitoring method comprises the following steps of S1, setting a temporary protection support; S2, scanning point cloud and carrying out data processing; S3, setting a crack identification module; S4, setting an inclination rate identification module; S5, setting a settling volume identification module; S6, setting a strain identification module; S7, performing early warning evaluation; and S8, conducting safe deviation rectification. According to the method, accurate point cloud data is obtained through real-time scanning, a monitoring module monitors the change of the inclination rate in the correction and reinforcement process and possibly-generated crack damage, settlement damage and strain damage, the problems of errors and construction safety caused by a manual monitoring mode and a semi-manual and semi-mechanical operation mode are avoided, and the correction accuracy, the monitoring efficiency and the structural safety are improved. Under the condition that secondary damage is not caused to an inscription cultural relic body, the safety, effectiveness and feasibility of the rectifying and reinforcing process of the vulnerable inscription cultural relic are ensured through an informatization monitoring mode.

Description

technical field [0001] The invention belongs to the field of protection and repair of ancient buildings, and in particular relates to a CNN-based real-time monitoring method for rectifying and strengthening tilted stele cultural relics. Background technique [0002] Stele cultural relics are an important part of traditional architectural heritage, which condenses the cultural achievements of social development and the accumulation of the times. However, because most of the existing stele cultural relics are preserved in the open air, they are usually relatively large in size and have a large height-to-width ratio. Susceptible to external factors such as foundation subsidence, earthquake damage, man-made destruction, plant growth, etc., and even lack of protection measures such as fences or glass shields, these monuments and cultural relics are often tilted and damaged to varying degrees, and some are on the verge of collapse. Moreover, stele cultural relics usually have a hi...

[0002] Stele cultural relics are an important part of traditional architectural heritage, which condenses the cultural achievements of social development and the accumulation of the times. However, because most of the existing stele cultural relics are preserved in the open air, they are usually relatively large in size and have a large height-to-width ratio. Susceptible to external factors such as foundation subsidence, earthquake damage, man-made destruction, plant growth, etc., and even lack of protective measures such as fences or glass shielding, these stele cultural relics are often tilted and damaged to varying degrees, and some are on the verge of collapse

Moreover, stele cultural relics usually have a history of hundreds or even thousands of years. The material properties of the stone have been degraded due to accumulated damage. There are many safety hazards in the correction process. Once new cracks are generated due to improper correction measures, it is easy to lead to brittle failure. risk of damage

In the current rectification and reinforcement process of stele cultural relics, the current rectification technology mainly conducts real-time monitoring through manual measurement, or installing sensors and cables on the cultural relics. It may cause secondary damage to the cultural relics. Therefore, more intelligent, efficient and reasonable monitoring methods are needed to ensure that the stele cultural relics are corrected and reinforced in a safe state.
