Detection method for architectural glass surface optical reflection image deflection

Abstract

The invention relates to a quality detection method for the deformation condition of glass surface optical reflected images caused by processing deformation of building glass. The quality detection method is to adopt a high-resolution digital camera and a computer system to observe images formed by a building glass surface optical reflected black and white square pattern test board, and measure and calculate the deflection of the side length and the angle of a shot black / white pattern image with the maximum deformation, or use a computer image recognition system to compare the variation of the building glass surface optical reflected black and white pattern images so as to evaluate the quality of the building glass through the percentage of the deflection of the images. The quality detection method can conveniently and intuitively detect the deflection of the glass surface optical reflected images caused by permanent deformation due to deep processing of the building glass, and is a convenient and reliable detection method required for quality control of the manufacturing process and quality inspection under the condition of delivery and acceptance inspection of products of the building glass.

Description

Detection method of optical reflection image deformation on architectural glass surface Technical field The invention relates to a quality inspection method of architectural glass. In particular, it is a quality inspection method for the deformation of the optical reflection image on the glass surface caused by the deep processing deformation of architectural glass. Background technique In order to ensure the product quality of architectural glass, many quality inspection methods have been formulated at home and abroad, and many relevant standards such as my country's GB national standard and ISO international standard have been promulgated and implemented. For example, GB / T7106 classification and detection method of wind pressure resistance performance of building exterior windows, GB / T8184 classification and detection method of thermal insulation performance of building exterior windows, GB / T8185 classification and detection method of airborne sound insulation performanc...
