An objective evaluation method of texture roughness based on human tactile perception characteristics

Abstract

The invention discloses an objective evaluation method of texture roughness based on human tactile perception characteristics. The clustering level of human subjective roughness; collect the interaction data when the surface of the unknown texture sample is in contact, and extract the objective characteristic parameters; use the support vector machine algorithm to classify the objective characteristic parameters of the unknown texture, and generate the objective characteristic parameters of the texture, The human subjective roughness clustering level is the input and output texture tactile roughness evaluation model, and the model parameters are obtained through training; the objective characteristic parameters of the texture to be evaluated are extracted and input into the model, and the output is the human subjective roughness clustering level. The invention simulates people's cognitive habits, is close to the real roughness evaluation process of people, and does not require the participation of a large number of experimenters, and has the characteristics of high efficiency, good result stability and high accuracy.

Description

technical field [0001] The invention relates to an objective evaluation method of texture roughness based on human tactile perception characteristics, and belongs to the technical field of force-tactile interaction. Background technique [0002] Roughness is an objective attribute of an object, which is affected by objective parameters such as texture period, texture height, material hardness, and friction coefficient. The roughness of the material has an important impact on people's work and life. According to different applications, the requirements for roughness are very different. [0003] The evaluation of texture roughness exists in both industrial manufacturing and daily life. The evaluation methods of texture tactile roughness include subjective evaluation process and objective evaluation process. The subjective evaluation process is generally given through the evaluation of subjective perception experiments, that is, let the subjects touch the texture samples with...
