The invention discloses a movable calibration system and method for increasing surface length measurement precision of strip steel. The system comprises a base, an upright pillar, a connecting plate, a crossbeam, an angle adjustment base, a speedometer and a speed sensor, wherein the upright pillar is mounted on the base, the connecting plate is movably mounted on the upright pillar and is fixed with the crossbeam to enable the crossbeam to be vertical to the upright pillar, the angle adjustment base is mounted at the tail end of the crossbeam, and the speed sensor is mounted on the angle adjustment base and is in signal connection with the speedometer. According to the movable calibration system, the precision performance of the strip steel can be stable and approximate to a real value, the length of the strip steel can be accurately controlled, the accurate positioning of defect positions can be realized, and the system can be applied to subsequent tracking and processing of defects.
Description
technical field [0001] The invention relates to on-line detection of strip surface quality based on machine vision, and more specifically relates to a movable calibration system and method for improving the precision of strip surface length measurement. Background technique [0002] The strip steel surface defect detection system uses images as the basic medium to collect, transmit and analyze images, calculate and evaluate the status of strip steel surface quality, and can generate quantitative and textual quality reports. With the continuous improvement of the requirements for the surface quality of the strip and the continuous increase of the production speed of the strip, the precise positioning of the surface defects of the strip is particularly prominent. In the past, more attention was paid to whether the weight of the steel strip met the customer's needs. For the location of defects, the length of the strip steel was less required, which affected the production outpu...
