A map updating method may include calculating a relative pose relationship between consecutive images; calculating an absolute pose of each image based on the relative pose relationship between the consecutive images; and updating a map used for visual localization (VL) based on the absolute pose.

Method and system for updating map for pose estimation based on images

The trajectory tracking method for a mobile electronic device may include tracking a trajectory of the electronic device by using results of pose estimation using odometry and results of pose estimation using visual localization (VL) as camera pose information.

Method and system for tracking trajectory based on visual localization and odometry

Electronic devices and/or operating methods of the electronic device to provide visual localization based on outdoor three-dimensional (3D) map information may be provided. Such electronic devices may be configured to acquire two-dimensional (2D) image information about an outdoor environment, generate 3D map information about the outdoor environment based on the 2D image information, and determine a position of a point in the 3D map information corresponding to a query image.

Electronic device for providing visual localization based on outdoor three-dimension map information and operating method thereof

A method for generating depth information of a street view image using a two-dimensional (2D) image includes calculating distance information of an object on a 2D map using the 2D map corresponding to a street view image; extracting semantic information on the object from the street view image; and generating depth information of the street view image based on the distance information and the semantic information.
