In terms of straw-burning smoke detection, Wang et al. [12] proposed a smoke-detection method based on an improved frame difference method and Faster R-CNN. For smoke detection, it first uses the ...
To validate effectiveness and robustness of the proposed method, data collected from 49 EVs of a certain brand are used in this study, where 34 vehicles are normal ones and 15 suffered from thermal runaway. All vehicles adopt 21,700 size silicon graphic/Ni x Co y Al z LIB cells as power source, which use NCA, graphite and Si, and …
The DETR model is often affected by noise information such as complex backgrounds in the application of defect detection tasks, resulting in detection of some targets is ignored. In this paper, AIA DETR model is proposed by adding AIA (attention in attention) module into transformer encoder part, which makes the model pay more attention to correct defect …
