In order to realize the intelligent recognition of unattended behavior in hot experiments of chemical laboratory,a recognition method based on target detection algorithm was proposed.The unattended behavior of hot experiments was defined,and six groups of scene simulation schemes were designed.Through the simulation of three different behavior modes,the image dataset required for model training and verification was constructed,and the recognition model for the unattended behavior of hot experiments in chemical laboratory was constructed based on the target detection algorithm.The results show that the recognition precision rate,recall rate and mAP@0.5 of the model integrating SimAM attention mechanism and using the WIoU loss function are 0.996,0.996 and 0.996,respectively.In the generalization ability test,the precision rate is 0.891,the recall rate is 0.783,and mAP@0.5 is 0.821.The recognition ability and generalization ability of the model after integrating the SimAM attention mechanism and using the WIoU loss function are significantly improved.The research results can provide technical support for the recognition and early warning of unattended behavior in hot experiments of chemical laboratories.
