A Mortar Plumpness Detection Method Based on Image Processing Technology

Abstract

The invention discloses a mortar fullness detection method based on image processing technology. Mortar fullness is an important indicator in the quality acceptance of masonry projects in the construction industry. It is expressed as the percentage of the contact surface area between bricks and mortar and the corresponding brick surface area. The current method used by practitioners to measure mortar fullness is manual measurement, which is time-consuming and labor-intensive. This invention first takes pictures of the bricks to be tested through a mobile phone, then uses the characteristic information of the bricks and mortar to identify the brick area in the image and obtains the brick image, then extracts the mortar area from the brick image, and finally based on the mortar area Mortar fullness is obtained as a percentage of the brick image. The present invention can obtain accurate measurement results by taking pictures of bricks to be measured with a mobile phone, and realizes fully automatic detection of mortar fullness. Compared with other current methods, the present invention greatly improves the detection efficiency of mortar fullness.

Description

technical field [0001] The invention belongs to the field of masonry engineering quality acceptance in the construction industry, and proposes a method for detecting the fullness of mortar based on image processing technology. Background technique [0002] Masonry engineering is an important part of construction engineering, which refers to the structure formed by bonding bricks and mortar and organizing them in a certain way. As a traditional structural form, masonry engineering has been widely used in construction engineering in my country. Among the existing residential buildings, office buildings and other civil buildings, industrial production buildings and other building structures, there are hundreds of millions of square meters of building structures that are masonry structures, and in some towns, a large number of masonry structures are still under construction. [0003] In order to ensure the quality of the masonry structure, it is necessary to detect the fullness...

Problems solved by technology

At the same time, in the process of recording the number of grids, it is difficult for practitioners to deal with the situation that the grids are not filled with mortar, thus increasing the error

Obviously, the current method of detecting the fullness of mortar is time-consuming and laborious
