专利汇可以提供Curvature shape measuring instrument for plate-like body专利检索，专利查询，专利分析的服务。并且PURPOSE: To improve the quality of a rolled product by obtaining linear images at three positions which are at intervals in the moving direction of the plate-like body simultaneously and finding the curvature shape from position information extracted from the linear images.
CONSTITUTION: When a steel plate 10 which is being rolled is carried by a table roller 24, a steel plate front end detector 12 detects whether or not the front end part of the steel plate 10 enters the visual field 15 of a video camera 16. When the front end part of the steel plate 10 is detected, the detection signal of the detector 12 is inputted to a camera controller 18. Then, the controller 18 uses the detection signal as a trigger signal and inputs the video information of the camera at the front end detection time point to an image processing part 20 for edge detection as a still image. Consequently, the processing part 20 obtains a still image of the flank of the steel plate 10. Then an arithmetic processing part 22 finds the curvature of the steel plate 10 from a specific expression based upon the coordinates of three points on the surface of the steel plate in the still image inputted from the processing part 20.
