A method for recognizing a valuable document, comprising the steps: collecting multimodal information of a valuable document to be recognized, wherein the multimodal information comprises two or more of optical information, electrical information, magnetic information and physical information of the valuable document to be recognized; recognizing the valuable document to be recognized according to a pre-generated fusion strategy and the collected multimodal information of the valuable document to be recognized, and obtaining a recognition result; wherein the step of recognizing the valuable document to be recognized according to the pre-generated fusion strategy and the collected multimodal information, and obtaining a recognition result comprises analyzing the multimodal information of the valuable document to be recognized and extracting features of the multimodal information, wherein the features comprise features to be fused and a feature not to be fused; fusing the features to be fused according to a preset fusion strategy, and obtaining a new fused feature of the multimodal information, wherein fusing the features to be fused according to a preset fusion strategy comprises fusing optical information under irradiation of red light, infrared light and ultraviolet light to obtain a new feature which contains three types of optical information of the valuable document to be recognized according to a weighted average method to obtain the new fused feature; and recognizing the valuable document to be recognized according to the features not to be fused and the new fused feature, and obtaining a recognition result. collecting multimodal information of a valuable document to be recognized, wherein the multimodal information comprises two or more of optical information, electrical information, magnetic information and physical information of the valuable document to be recognized; recognizing the valuable document to be recognized according to a pre-generated fusion strategy and the collected multimodal information of the valuable document to be recognized, and obtaining a recognition result; wherein the step of recognizing the valuable document to be recognized according to the pre-generated fusion strategy and the collected multimodal information, and obtaining a recognition result comprises analyzing the multimodal information of the valuable document to be recognized and extracting features of the multimodal information, wherein the features comprise features to be fused and a feature not to be fused; fusing the features to be fused according to a preset fusion strategy, and obtaining a new fused feature of the multimodal information, wherein fusing the features to be fused according to a preset fusion strategy comprises fusing optical information under irradiation of red light, infrared light and ultraviolet light to obtain a new feature which contains three types of optical information of the valuable document to be recognized according to a weighted average method to obtain the new fused feature; and recognizing the valuable document to be recognized according to the features not to be fused and the new fused feature, and obtaining a recognition result.
