Material analysis method and device based on texture surface contact acceleration touch sense information

Abstract

The invention provides a material recognition method based on texture surface contact acceleration touch sense information, and belongs to the fields of electronic information, artificial intelligence, mode recognition and machine learning. The method includes the steps of: 1) dividing objects into different material subclasses, selecting objects corresponding to the different material subclasses, and collecting triaxial acceleration data to configure a training sample data set; 2) extracting features from the training samples to obtain fusion feature vectors of the material subclasses, which form a fusion feature matrix; 3) training a feed-forward neural network by means of the matrix, and collecting the triaxial acceleration data of a to-be-tested object and extracting the features, feeding the features to the feed-forward neural network, and predicting and outputting a subclass material, which is corresponding to a maximum value in the matrix, by the network, thereby obtaining the material analysis result of the to-be-tested object. The device includes a vibration sensing body, a data collection module and an upper computer. In the method, by acquiring the contact acceleration information of the surface texture of a commodity, the material of the commodity is determined. The method and the device are applied to internet shopping and can easily, accurately and effectively reflect the actual situation of a 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...
