A multi-source elevation data fusion method including: inputting acquired optical elevation data into a trained optical elevation error prediction model to output an optical elevation error value and an optical elevation error weight map; inputting acquired radar elevation data into a trained radar elevation error prediction model to output a radar elevation error value and a radar elevation error weight map; correcting the optical elevation data based on the optical elevation error value to obtain optical elevation data to be fused; correcting the radar elevation data based on the radar elevation error value to obtain radar elevation data to be fused; performing weighted fusion on the optical elevation data to be fused and the radar elevation data to be fused based on the optical elevation error weight map and the radar elevation error weight map to obtain fused elevation data. This method efficiently enhances the accuracy of fused elevation data.
