Example Embodiment

[0077] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0078] The non-contact fabric surface roughness test method of the present invention includes the following steps:

[0079] (1) Obtain an image of the fabric;

[0080] Fold the fabric in the warp or weft direction to obtain a frame of image containing the contour lines of the fold perpendicular to the plane of the fabric;

[0081] (2) Obtain multiple frames of images of the fabric;

[0082] Repeat step (1) n times to obtain images of n frames of...

Abstract

The invention relates to a non-contact type fabric surface roughness test method and a non-contact type fabric surface roughness test device. The non-contact type fabric surface roughness test device comprises two rotating wheels fixed at both ends of a first wheel shaft, two rotating wheels fixed at both ends of a second wheel shaft, and frame plates which are fixed on the first wheel shaft and the second wheel shaft and form a rectangular frame with the first and second wheel shafts, wherein fabric encircles the first wheel shaft and the second wheel; a camera is arranged above the top end of the first wheel shaft; and a frame of image is photographed every time the first wheel shaft rotates by a certain degree. The non-contact type fabric surface roughness test device is simple in structure, and the implemented test method can achieve the requirement of measuring surface roughness accurately, stably and quickly.

Description

technical field [0001] The invention belongs to the technical field, and relates to a non-contact fabric surface roughness test method and a test device. Background technique [0002] During the construction and operation of subway track projects, water problems often occur, not only groundwater, rainwater, tidal backflow, but also seasonal rainstorms or floods. A large amount of water will flow from the ventilation holes of the subway and the subway stations The entrance and exit pour into the tunnel, and the pouring of a large amount of water will destroy the electrical system and signal system of the subway line, causing huge economic losses, and even endangering people's lives in severe cases. Therefore, how to quickly and effectively prevent a large amount of water from entering the subway tunnel has become an instant problem. [0003] Generally, tunnel waterproofing is composed of two parts: structural waterproofing technology and material waterproofing technology. T...
