A laser radar-camera online calibration method and system based on a reflectance map includes: data preprocessing, generating data that meets the input of the neural network part; inputting the preprocessed data into the trained neural network; the neural network will output the edge point features of the reference image and the reflectance map, that is, the reference image and the reflectance map descriptor; by comparing the similarity of the reference image and the reflectance map descriptor, find the matching relationship between the reference image feature and the reflectance map feature point; use the mapping relationship between the reflectance map and the 3D point cloud to find the matching relationship between the reference image and the point cloud; use the EPnP algorithm to estimate the transformation matrix from the given 2D-3D point pair to complete the calibration process.
