Abstract

The invention discloses a texture feature clustering-based locomotive wheelset tread damage detection method. According to the method, a damage suspected region is determined through a tread image block texture clustering method; damage contour point detection is performed in the suspected regions through using gradient information; seed points are determined according to detected damage contour points; and a maximum likelihood estimation and 3sigma principle-based regional growth technology is adopted to segment the damage region based on the seed points; and a directional structural element-based morphological region merging technology is adopted to obtain a final damage detection result. The texture feature clustering-based locomotive wheelset tread damage detection method can accurately and efficiently judge the tread damage of a locomotive in a locomotive wheelset on-line detection system and has high practicability and a bright application prospect.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to a method for detecting damage to the tread of a locomotive wheel set based on texture feature clustering. Background technique [0002] The locomotive wheel set is one of the main parts of the locomotive running, whether it can work normally will directly affect the running safety of the locomotive. The damage of the locomotive wheel to the tread is an important factor affecting the operation of the locomotive. Therefore, whether the damage to the locomotive tread can be detected correctly plays a vital role in the normal operation of the locomotive. [0003] Locomotive wheel tread damage is an irregular surface defect formed during locomotive operation. Common tread damages include: scratches, peeling, etc. At present, due to the emergency braking of the locomotive, the material of the tile between the wheels is not strong, the adjustment device of the empty a...
