Method and device for material analysis based on contact acceleration tactile information of textured surface

Abstract

The invention proposes a material identification method based on acceleration tactile information of texture surface contact, which belongs to the fields of electronic information, artificial intelligence, pattern recognition and machine learning. This method first divides the items into different material categories, selects corresponding items for each material category and collects triaxial acceleration data to form a training sample data set; extracts features from the training samples to obtain the fusion feature vector of each material category Form a fusion feature matrix; after using the matrix to train the feedforward neural network, collect the triaxial acceleration data of the item to be tested and extract the features, input the feedforward neural network, and the network predicts that the fine material corresponding to the maximum value in the output matrix is ​​the material to be tested The results of the material analysis of the test object. The device includes: a vibration receptor, a data acquisition module and a host computer. The present invention judges the material of the commodity by obtaining the contact acceleration information of the surface texture of the commodity material, is applied to Internet shopping, and simply, accurately and effectively reflects the real situation of the commodity.

Description

technical field [0001] The invention relates to a material analysis method and device based on texture surface contact acceleration tactile information, belonging to the fields of electronic information, artificial intelligence, pattern recognition and machine learning. Background technique [0002] In recent years, with the advent of the information age and the continuous development of Internet technology, people are increasingly relying on the use of the Internet to purchase goods. Although Internet shopping facilitates people's behavior, people often can only use the picture information provided by the merchant. The material of the product is judged from the visual senses, and the picture information often cannot fully reflect the accurate information of the material of the product. [0003] Touch is an important form of perception that can acquire finer texture properties compared to vision. The texture of the material surface is the embodiment of the distribution char...
