Building formwork construction monitoring system based on the principle of digital image measurement

Abstract

The invention relates to a building formwork construction monitoring system based on the image measurement principle. The system comprises a center control computer, a binocular camera unit, a laser ranging unit and an early warning unit. Two cameras of the binocular camera unit shoot digital images of a formwork at preset time intervals and transmit the images to the center control computer, and then the center control computer processes, calculates and analyzes the images; the laser ranging unit measures the distance between a laser range finder and the shot formwork and transmits the distance data to the center control computer in real time; the center control computer carries out feature point recognition on the digital images and calculates the three-dimensional deformation and the movement tendency of the shot formwork according to the parallax of the same feature points in the images shot by the two cameras. According to the system, the non-contact image measurement method is adopted, instruments are easy to operate, the deformation condition of the formwork is shown in real time, and possible conditions of the formwork are prejudged. Thus, the system can be widely applied to building construction.

Description

technical field [0001] The invention belongs to the field of building formwork construction safety, and relates to an early warning system, in particular to a building formwork construction monitoring system based on the principle of digital image measurement. Background technique [0002] Formwork construction technology is a construction method in reinforced concrete engineering that is highly mechanized, fast in construction speed, occupies less space, has guaranteed safe operation, significant comprehensive benefits and can be reused. Especially in the construction of cast-in-place reinforced concrete structures in high-rise and super high-rise buildings, formwork is a construction tool widely used in large areas. It has a high reuse rate, saves a lot of cost and construction period, and has a certain guarantee for project quality. However, during the construction process, due to the quality problems of the formwork itself, insufficient support, not strong enough, improp...

Problems solved by technology

Existing formwork monitoring is mainly performed by professionals regularly. Due to the large error of direct observation and easy omission, the phenomenon of mold expansion and mold explosion occurs from time to time.
