Abstract

The invention provides a non-contact concrete segregation degree intelligent real-time analysis method and device. the method comprises the following steps: inputting each group of flowing concrete video preprocessing images into a segregation degree analysis model obtained through pre-training, and obtaining concrete anti-segregation performance labels respectively corresponding to each group of mobile concrete video preprocessing images; and determining the segregation degree of the concrete according to the anti-segregation performance label of the concrete. According to the invention, the segregation degree of the concrete in the flowing concrete video image can be analyzed.

Description

technical field [0001] The application relates to the technical field of concrete work performance detection, in particular to a non-contact intelligent real-time analysis method and device for segregation degree of concrete. Background technique [0002] Concrete has become one of the most widely used building materials because of its good plasticity in the fresh stage and good mechanical properties after hardening. With the popularity of concrete admixtures, concrete has been more and more widely used, and the convenience of construction has been greatly improved. The type of concrete has also changed from plastic and dry hard concrete to fluidity and high fluidity concrete. However, as the fluidity of concrete increases, its homogeneity becomes more difficult to control. The homogeneity of concrete has a significant effect on its properties after hardening. Therefore, controlling the homogeneity of concrete is of great significance to the quality assurance of buildings...
