Abstract: Highlights•An efficient near-infrared characterization method based on the conversion of one-dimensional time series signals into images.•Through image conversion and data balancing, a high-precision cognitive scale and near-infrared multi-modal fusion method are proposed.•Screen cognitive scales in the preprocessing stage and fusion stage to improve detection efficiency while maintaining classification accuracy.
