Children autism early evaluation device and system based on video hierarchical comparative analysis and grade behavior normal form

Abstract

The invention relates to the technical field of early evaluation of children autism, in particular to a device and a system for early evaluation of children autism based on video hierarchical comparative analysis and a grade behavior normal form. The system includes a data acquisition demonstration module, a data acquisition module, a data uploading module, a data rationality judgment module, a feature extraction module, a classifier training module and a prediction evaluation module. According to the early evaluation device and system for the autism of children, the requirement for shooting equipment can be lowered, meanwhile, participation of professionals and strangers is not needed, testers can conduct early screening and evaluation on pedigree disorders under accompanying of family members and in a familiar environment, and therefore the actual situation can be reflected more truly. Besides, the system also fully considers the difficulty level of simulating different behavior paradigms of the children, and evaluates the behavior paradigms of the testees from global and local angles, so that the illness condition of the pedigree disorder of the testees is evaluated more accurately.

Description

technical field [0001] The invention relates to the technical field of early assessment of children's autism, in particular to a device and system for early assessment of children's autism based on video hierarchical comparison analysis and hierarchical behavior paradigm. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] Autism Spectrum Disorder (ASD, Autism Spectrum Disorder, referred to as autism) is a disease of brain development disorder, which is mainly manifested as slow development of behavioral ability, language ability and social ability, which are significantly lower than normal children. In the early days, many parents often mistakenly believe that ...

[0005] Chinese patent application with application number 201811217575.3 "Primary Screening Device for Autism Based on Separation and Reunion Paradigm and Computer Vision", Chinese Patent Application No. 201910605990.4 "Early Screening System for Autism Based on Smile Paradigm and Audio-Video Behavior Analysis", Chinese patent application number 201910606484.7 "Autism Assessment System Combining Questionnaire and Multimodal Paradigm Behavior Data Analysis", Chinese patent application number 201910053035.4 "A vision-based aided early screening method and device for autism" and The Chinese patent application number 201910605991.9 is "Autism Assessment Device and System Based on Parrot Language Paradigm Behavior Analysis". For most ordinary families, these devices are not only expensive, but also need to be completed under the guidance of professionals. In this way, related devices and systems cannot be quickly popularized in ordinary families.

The Chinese patent application number 201910606484.7 "Autism Assessment System Combining Questionnaire and Multimodal Paradigm Behavioral Data Analysis" uses questionnaires and multimodal data to evaluate children's autism, although the use of multi-source data can improve children's autism. The accuracy of the early evaluation, but the shooting process or the data provided are more complicated, which also increases the difficulty of its promotion

[0006] In addition, the inventors also found that: the prior art treats each behavioral paradigm equally when assessing children with suspected autism, but for many children with suspected autism, the difficulty level of simulating each behavioral paradigm is different
