Disclosed herein method and apparatus for detecting changes between heterogeneous image data for identifying disaster damage. The method includes obtaining observation image data of an event occurrence region and reference image data that occurs before an event and has a heterogeneous type of an image from the observation image data; processing the observation image data and the reference image data according to an attribute of the observation image data and preprocessing the observation image data and the reference image data to determine whether or not there is an exceptional object to be excluded from a change analysis in the processed observation image data and the processed reference image data based on an event type and to process the exceptional object; and detecting a change area of the event occurrence region based on the preprocessed observation image data and the preprocessed reference image data.
