Steel plate coating quality prediction method and preset data acquisition method

The invention relates to the technical field of steel plate surface quality detection, and discloses a steel plate coating quality prediction method and a preset data acquisition method. The prediction method comprises the following steps: acquiring a first rough value of a color difference area of a steel plate; acquiring a second roughness value of a non-chromatic-aberration area of the steel plate; and predicting the coating quality of the steel plate according to the first roughness value and the second roughness value. By detecting the roughness values of the chromatic aberration area and the non-chromatic aberration area, the quality of the coating appearance of the steel plate is predicted in advance, the time is saved, the process cost is saved, and the overall production quality is improved. 本申请涉及钢板表面质量检测技术领域，揭示了一种钢板涂镀质量的预测方法及预设数据获取方法。所述预测方法包括：获取钢板的色差区域第一粗糙值；获取钢板的非色差区域第二粗糙值；根据所述第一粗糙值和所述第二粗糙值预测钢板的涂镀质量。通过检测色差与非色差区域的粗糙值，进而提前预测钢板涂装外观的质量，节省时间，节省工序成本，提高整体的生产质量。
