In garment manufacturing, an automatic sewing machine is desirable to reduce cost. To accomplish this, a high-speed vision system is required to track fabric motions and recognize repetitive weave patterns with high accuracy, from a microperspective near a sewing zone. In this letter, we present an innovative framework for real-time texture tracking and weave pattern recognition. Our framework includes a module for motion estimation using blob detection and feature matching. It also includes a module for lattice detection to facilitate the weave pattern recognition. Our lattice-detection algorithm utilizes blob detection and template matching to assess pair-wise similarity in blobs' appearance. In addition, it extracts information of dominant orientations to obtain a global constraint in the topology. By incorporating both constraints in the appearance similarity and the global topology, the algorithm determines a lattice that characterizes the topological structure of the repetitive weave pattern, thus allowing for thread counting. In our experiments, the proposed thread-based texture tracking system is capable of tracking denim fabric with high accuracy (e.g., 0.03° rotation and 0.02 weave-thread translation errors) and high speed (3 frames per second), demonstrating its high potential for automatic real-time textile manufacturing.
Monitoring of the operating conditions of structures is an important task that provides essential data for their in-service evaluation and fault prevention. To fulfil this task, monitoring sensors may be installed on or around a machine or a structure, with their associated wiring, data transmission and processing electronics used to provide measurement data for human supervision and possible human or automatic intervention.second hand tailoring machine in chennai, perambur, mylapore, madipakkam
The measurement of vibrations is an important technique that has been used to monitor the conditions of machines and civil structures for maintenance, intervention and replacement purposes . Among the important factors to consider for such a monitoring system are its safety of operation and immunity to hazards, the robustness of the sensors and complexity of the required wiring, and the possibility of interference signals pick up by the sensing system. These would eventually affect the cost-effectiveness of the installation and operation of the monitoring system equipment. Some of these factors favour optical fiber sensors as the best candidates to use in many applications, for their very nature of being made of insulating materials and operated by lightwaves trapped inside fibers which are difficult to interfere with . The optical sensors could possibly be realized in robust configurations and can further be networked by their connecting fibers to achieve the operation of many sensors using reduced wiring and cost-effective installations.
