  • Abstract On-line gap measurement techniques for steel mill non-contacting conveyance system, which can supply accurate, rapid and high-sampling rate gap measurements, have been proposed. To realize the entire process, by considering the operational environment in a steel mill and combining with those available system dimension measurement instruments, an image-based scheme with proper image processing and parameter calibration process has been developed. The possible sources that affect the air-gap detection accuracies have also been thoroughly investigated, and a comprehensive measurement database and a recursive modification technique have been successfully established. In order to achieve stable control for site implementation, an integrated optical inspection system which combined with the high-speed rate line-scan camera has been designed. From the experimental results, the proposed system can both provide accurate gap values at the static state, and offer stable control operations at the dynamic state. It is believed that the proposed scheme provide innovated guidance for the related conveyance applications in the steel mill.
