specific Embodiment approach 1

[0033] Specific embodiment one: a kind of glass panel degumming recognition method based on image method described in this embodiment, described method comprises the following steps:

[0034] Step 1: Use a camera to collect images of a certain range of identified glass panels, and the images at least include a frame of the glass panel with structural glue. For a small-scale glass panel, images can be acquired by manual direct photography. For a large range of glass panels, it is possible to use a drone to carry a camera to take pictures, or use a robotic arm to carry a camera to take pictures. The range of image collection is larger and the detection efficiency can also be improved.

[0035] At the same time, the size of the image and the number of glass panels included should be such that the structural adhesive strips can be clearly distinguished. Therefore, it is advisable to take pictures at 90 degrees to the plane of the glass curtain wall, or at a certain angle (such as...

Abstract

The invention discloses a glass panel degumming identification method based on an image method, and relates to the technical field of nondestructive testing. The invention aims to solve the problem oflow detection efficiency of the existing detection method for degumming between an outer-layer glass plate and a structural adhesive on a glass curtain wall. According to the principle that the interface between the glass and the structural adhesive disappears due to degumming, so that remarkable color change is generated, the color characteristics of the bonding area of the glass panel and the structural adhesive in the glass panel image are extracted, then gray scale and binarization processing is carried out, and whether degumming happens to the glass panel or not is judged according to the binarized black and white image. The method is suitable for identifying the degumming phenomenon of the structural adhesive of the glass window and the frame.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing, in particular to the detection of degumming of glass curtain walls. Background technique [0002] Glass curtain wall is widely used in modern buildings at home and abroad because of its excellent use experience such as light transmission, sound insulation, aesthetics, and waterproof. Like all building structural materials, glass curtain walls have loosening, weakened connection stiffness, and performance degradation in their components and materials during long-term use. The above factors lead to the reduction or even failure of the connection strength of multiple connection links between the glass plate on the glass curtain wall and the skeleton structure behind it. Under the action of external load, the connection may be damaged, thereby causing the glass plate to fall off. The high-altitude fall of the glass plate will cause casualties and property damage, resulting in serious...
