AI Technical Summary

Technical Problem

Current crane operator examinations rely on manual observation and subjective judgment, which are subjective and inconsistent. They cannot accurately assess multi-dimensional information during operation, resulting in scores that cannot fully reflect the operator's real-time status and actual ability.

Method used

A smart examination method based on thermal imaging is adopted. Infrared thermal imaging technology and skeleton recognition technology are used to obtain infrared heat source data of crane structural nodes and skeleton node coordinates of operators. Information extraction neural network and fuzzy logic rules are combined to conduct multi-dimensional evaluation. Bayesian estimation is used to estimate the probability of skill level, and finally an objective and fair score is generated.

Benefits of technology

It achieves comprehensive capture of operators' explicit behaviors and implicit influences, ensuring the objectivity, fairness and efficiency of the scoring. It can automatically extract key behavioral patterns, improve assessment efficiency, reduce safety risks, and provide detailed scoring feedback and training suggestions.

Abstract

The present application relates to crane training technical field based on thermal imaging crane wisdom examination method, examination system and medium. Crane wisdom examination method includes: obtaining infrared heat source data, coordinate of crane structure node, and skeleton node coordinate of operator, and processing to obtain high-dimensional feature vector Z , linear mapping obtains preliminary score. Through fuzzy logic rule, bayesian estimation method is handled to X With X It is input into evaluation neural network to obtain secondary score. The preliminary score and the secondary score are fused to obtain the final score, if the final score is greater than the threshold, the examination passes. The present application combines infrared thermal imaging technology and skeleton recognition technology, can capture the dominant behavior of the examinee operation and its hidden influence on the equipment at the same time, and reflect this potential bad operation habit in the final score, so as to fully reflect the real-time state and actual ability of the operator.
