The invention relates to the technical field of intelligent monitoring, in particular to a road monitoring device based on multi-source data fusion, which comprises a distributed fiber bragg grating sensing module for collecting various data of each monitoring area of a roadbed and a road surface; the optical signal processing module is used for analyzing the data acquired by the distributed fiber grating sensing module and judging whether the data exceed respective threshold values or not; the imaging radar and the low-illumination camera are used for acquiring radar point cloud images and visible light images of a road and a slope area; the image processing module is used for fusing the radar point cloud image and the visible light image of the same monitoring area and identifying whether rockfall, fracture or collapse conditions exist in each monitoring area on the road or not; and the alarm module is used for sending out a corresponding alarm signal when any one of the data acquired by the distributed fiber grating sensing module exceeds a threshold value or rockfall, fracture or collapse conditions exist in a certain monitoring area. According to the invention, the monitoring precision of road abnormal conditions can be improved.
