Notes:
Aiming at different ground surfaces of hardened bearing steel GCr15, this paper madeexperimental research on assessment method of surface roughness based on computer visiontechnology. Firstly, some pre-processing of the ground images should be carried out to eliminatenoise and get more detail information, including image enhancement and median filtering. Then themethod of power spectrum analysis transformed representation of processed image from spatialdomain to frequency domain by adopting two-dimensional Discrete Fourier Transform. Gaining themean power spectrum named E and its corresponding radius r, we made efforts to seek the directionin which the arithmetic average surface roughness Ra varied according to E and r. After that thevariation rule can be regarded as an assessment basis of ground surface roughness
