[0002] Building guardrails are currently widely used in public buildings, civil buildings, industrial buildings and municipal engineering. Guardrails play a key role in protecting people's activities. The building guardrail's resistance to horizontal loads, vertical loads, soft heavy object impacts and wind pressure are several performance indicators that are focused on during the building guardrail acceptance process; during the test of the building guardrail's resistance to horizontal loads, vertical loads, soft heavy object impacts and wind pressure, the deformation of the guardrail handrail needs to be measured; currently, contact measuring devices (such as spring displacement meters) are mostly used for deformation detection; contact measuring devices have obvious usage defects when facing guardrails for impact load tests. On the one hand, the contact measuring device is easily impacted during the measurement process. On the one hand, the measurement accuracy is reduced due to the influence of load (vibration disturbance) (the guardrail handrails are mostly circular or elliptical cross-section profiles, and contact measurement is easy to slip). On the other hand, the contact measurement device is easily affected by the impact load, which leads to poor stability. The vertical and contact measurement device usually needs to be arranged close to the guardrail handrail, and the guardrail is usually placed on the tread. Due to the limited width of the tread, it is easy to make the contact measurement device very difficult to stand on the tread, and sometimes even unable to complete the test. At present, there is a lack of a non-contact deformation measurement system to facilitate people to carry out deformation measurement of building guardrails.
