Abstract: A method performed by an electronic device, the electronic device, and a storage medium are provided. The method includes obtaining a frame image of a video from a camera and inertia data of an inertial measurement unit (IMU) corresponding to the frame image and obtaining a camera position and pose of the camera, a sparse map, and a high-density map corresponding to the frame image, based on the frame image and the inertia data of the IMU.
