Abstract

The invention puts forward a stone material surface roughness on-line detection device and a stone material surface roughness on-line detection method, and belongs to the technical field of stone material surface quality detection. The device comprises a base, a liftable bracket, a camera, an enlarger lens, a circular light source, a camera obscura, a positioning device, an image acquisition card, and a computer. The method has a simple process, and is easy to operate. Problems such as low precision and unstable detection caused by subjective factors and proficiency are overcome. An optical technology, a computer technology, a digital image processing technology and an on-line precision measurement technology are integrated. The surface glossiness of a stone material can be detected online, the detection result can be fed back to a detection system in real time, and stone roughness detection can be completed automatically. A plurality of problems of stone enterprises, such as low detection efficiency and unstable detection, are solved effectively.

Description

technical field [0001] The invention belongs to the technical field of stone surface quality detection, and in particular relates to an online detection device and method for stone surface roughness. Background technique [0002] In recent years, with the development of the domestic construction industry and the continuous improvement of people's living standards and low-carbon environmental protection awareness, natural stone with brilliance is popular in architectural decoration. However, due to the limitation of my country's stone production technology level, the product quality is uneven. Uneven, so stone surface detection is particularly important. [0003] At present, the vast majority of enterprises in my country still use the traditional manual inspection method, placing the stone within the range of artificial vision, first adjusting the angle of illumination of the light, then inspecting the surface quality of the product through observation, and finally classifying...
