Position and pose determining method, apparatus, smart device, and storage medium

An electronic device, comprising a memory and one or more processors, and a plurality of programs stored in the memory, wherein the plurality of programs, when executed by the one or more processors, cause the electronic device to perform a method for displaying a virtual character in a plurality of real-world images captured by a camera including:

• capturing an initial real-world image using the camera;
• simulating a display of the virtual character in the initial real-world image;
• capturing a subsequent real-world image using the camera after a movement of the camera;
• determining position and pose updates of the camera associated with the movement of the camera from tracking one or more feature points in the initial real-world image and the subsequent real-world image;
• and
• adjusting the display of the virtual character in the subsequent real-world image in accordance with the position and pose updates of the camera associated with the movement of the camera.

A non-transitory computer-readable storage medium storing a plurality of programs that, when executed by one or more processors of an electronic device, cause the electronic device to perform a method for displaying a virtual character in a plurality of real-world images captured by a camera including:

• capturing an initial real-world image using the camera;
• simulating a display of the virtual character in the initial real-world image;
• capturing a subsequent real-world image using the camera after a movement of the camera;
• determining position and pose updates of the camera associated with the movement of the camera from tracking one or more feature points in the initial real-world image and the subsequent real-world image;
• and
• adjusting the display of the virtual character in the subsequent real-world image in accordance with the position and pose updates of the camera associated with the movement of the camera.
