The present invention relates to the technical field of street cleanliness assessment, and discloses a real-time street cleanliness assessment method based on multimodal data fusion. The method first obtains the initial acquisition parameters and original monitoring data of the multimodal sensing device. These data contain overlapping area environmental information and are acquired in a preset direction. The original data is then subjected to multimodal preprocessing to extract heterogeneous feature difference points and generate a correlation relationship map. The effective monitoring range is then divided based on the map, and the acquisition parameters are adjusted to form an optimized parameter set. The adjusted data is then aligned in time and space to generate a multi-source data sequence. Finally, the overlapping areas are fused to eliminate feature conflicts and information redundancy, and a real-time assessment result is generated. In addition, the correlation relationship map can be corrected in combination with manual inspection records. This method can effectively fuse multimodal data, realize real-time and accurate assessment of street cleanliness, and improve the reliability and adaptability of the assessment.
