Workpiece roughness measuring method and device based on mobile terminal, terminal and medium

The invention discloses a workpiece roughness measurement method and device based on a mobile terminal, a terminal and a medium, and the method comprises the steps: obtaining an image, shot by the mobile terminal, of a workpiece surface based on an amplified workpiece surface; acquiring a focusing area of the image and performing image enhancement on the focusing area; extracting feature data of the image based on a gray level co-occurrence matrix algorithm; and inputting the feature data into a pre-constructed convolutional neural network to obtain the roughness of the workpiece surface. Compared with the prior art, according to the scheme, the mobile terminal is used for shooting the image, the shot image is subjected to image processing, and then the roughness is recognized through the convolutional neural network. And on-line accurate measurement is realized without taking down a workpiece. 本发明公开了一种基于移动终端的工件粗糙度测量方法、装置、终端及介质，上述方法包括：基于放大的工件表面，获取移动终端拍摄的工件表面的图像；获取所述图像的聚焦区域并对所述聚焦区域进行图像增强；基于灰度共生矩阵算法，提取所述图像的特征数据
