Method for detecting surface defects of strip steel

The invention discloses a method for detecting surface defects of a strip steel, the method is as follows: calibrating a parameter, a detection brightness and a gray value of a camera to obtain a calibration parameter; and photographing a strip steel to be detected according to the calibration parameter to obtain a strip steel picture; performing an effect test on detection software based on a pre-collected picture containing the defects; performing parameter adjustment on the detection software according to the results of the effect test to obtain an adjusted parameter; and testing the stripsteel picture based on the adjusted parameter. The method solves the technical problem that the detection result is inaccurate in the prior art. 本发明公开了种带钢表面缺陷的检测方法，该方法包括：对相机的参数、检测亮度以及灰度值进行标定，获得标定参数；根据所述标定参数对待检测的带钢进行拍摄，获得带钢图片；基于预先收集的包含缺陷的图片对检测软件进行效果测试；根据效果测试的结果对所述检测软件进行参数调整，获得调整后的参数；基于所述调整后的参数对所述带钢图片进行检测。本发明的方法解决了现有技术中存在检测结果不准确的技术问题。
