Title:
METHOD FOR DETECTING WATER ABSORPTION PROCESS OF CONCRETE SURFACE
Document Type and Number:
WIPO Patent Application WO/2017/028717
Kind Code:
A1
Abstract:
A method for detecting a water absorption process of a concrete surface (1001) comprises: spraying water to a to-be-detected concrete surface (1001) (1101); recording time-varying color or brightness of an image of the to-be-detected concrete surface (1001) in a water absorption process (1103); and computing, according to the recorded time-varying color or brightness of the image, an index value representative of the water absorption process (1105). A concrete surface (1001) is processed in real time by means of a shooting and computing capability of a smart phone (1004); by adding an identification image (1002) and utilizing an image processing technology, an actual water spraying range of water spraying at each time is accurately computed, so as to make it possible to compute the yield of water within unit area; and by means of a fixed water spraying quantity and a water spraying tool (1003) having a uniform spraying function, the certainty of the water spraying quantity at each time is ensured, and the test accuracy is guaranteed.
