Building deflection determination method and device and electronic equipment

Abstract

The invention discloses a building deflection determination method and device and electronic equipment. The method comprises the following steps: acquiring a reference image and at least one to-be-measured image of a target building; and performing correlation matching on the to-be-detected images according to the template images in the reference image, determining target matching areas corresponding to the to-be-detected images, and determining the deflection of the target building based on the position change of the target matching areas corresponding to the to-be-detected images and the template images so as to determine the deflection of the target building based on image matching. According to the embodiment of the invention, the invention improves the accuracy of the determined building deflection while improving the determination speed of the building deflection, is suitable for the measurement of the deflection of a building with lower contrast, and is also suitable for the determination of the deflection in a scene with a harsh measurement environment.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of building deformation testing, in particular to a method, device and electronic equipment for determining building deflection. Background technique [0002] Buildings such as bridges, house beams, and high-rise buildings are related to the safety of people's lives and property. Deflection refers to the bending value of a building or its components in the horizontal or vertical direction. For example, the middle part of a bridge will bend downward, and high-rise buildings will bend sideways. As an important key indicator of building safety evaluation, deflection is an important part of building inspection, which can directly reflect whether the deformation of building structure exceeds its safe allowable range, and can provide effective parameters for damage identification and health monitoring of building structures.

[0003] Exemplary, the current methods for measuring the deflection of bridges mainly include the following: the level method, using the measuring tool leveling rod and level to measure the vertical height difference between two points on the bridge surface to calculate the deflection value, and the measurement environment requirements are relatively harsh , and the range of measuring deflection is relatively small, and the measuring points should not be too many; the dial indicator and dial indicator measurement method uses the gear rotation device to amplify the displacement data transmitted by the measuring rod, and the detected data is in the circular The display on the dial can only be used under the bridge or in the occasion where the support can be erected on the bridge pier. The support must be erected, which leads to low work efficiency, not very convenient to use, and great limitations in field application; connecting pipe measurement The method uses the principle of "communicator", that is, the pressure at the same level is the same. The connecting pipe method generally uses a soft plastic pipe with a diameter of about 10mm and some three-way connectors. The connecting pipe is placed on the bridge. The millimeter scale is read manually, but the accuracy is low; the laser interferometer method, the prism or reflector is installed on the point to be measured, and then the laser interferometer is used to measure the distance change of the observation point, but the vibration amplitude of the bridge After exceeding a certain range, the light spot will not be captured, and the corresponding measurement effect will not be achieved; digital image processing technology measurement method, post or fix a special-shaped target on the bridge, and calculate the position of the target in the two images before and after the bridge displacement displacement, and then calculate the actual displacement of the bridge through spatial coordinate conversion, but it is necessary to install a target on the side of the bridge or the box girder of the bridge. The construction needs to be licensed by the government and has certain technical difficulties. It cannot be operated portable Require
