Abstract: To estimate a position of a moving object, an electronic device generate two-dimensional (2D) feature point information of a landmark-based probability map from the surrounding image, obtain landmark-based three-dimensional (3D) feature point information from the HD map data, convert one of the 2D feature point information of the surrounding image to 3D or the 3D feature point information of the HD map data to 2D, determine a similarity between the converted feature point information and one of the feature point information of the surrounding image and the feature point information of the HD map data that is not converted, and estimate a position of the moving object based on the similarity.
