3d model reconstruction method, electronic device, and non-transitory computer readable storage medium thereof

An electronic device, comprising:

• a processing circuit;
• a depth camera electrically connected to the processing circuit;
• at least one pose tracking sensor electrically connected to the processing circuit and arranged on the electronic device;
• and
• a memory electrically connected to the processing circuit and configured to store at least one program configured to be executed by the processing circuit, the at least one program comprising instructions for performing a 3D model reconstruction method comprising:
• receiving depth data of a target object corresponding to a current time spot from the depth camera;
• receiving camera pose data of the depth camera corresponding to the current time spot from the pose tracking sensor operated based on electromagnetic radiation;
• generating posed 3D point clouds corresponding to the current time spot according to the depth data and the camera pose data;
• generating posed estimated point clouds corresponding to the current time spot according to the camera pose data corresponding to the current time spot and a previous 3D model corresponding to a previous time spot;
• and
• generating a current 3D model of the target object according to the posed 3D point clouds based on a difference between the posed 3D point clouds and the posed estimated point clouds.

A non-transitory computer readable storage medium storing at least one program, comprising instructions, which when executed, causes a processing circuit to perform a 3D model reconstruction method comprising:

• receiving depth data of a target object corresponding to a current time spot from a depth camera;
• receiving camera pose data of the depth camera corresponding to the current time spot from at least one pose tracking sensor operated based on electromagnetic radiation;
• generating posed 3D point clouds corresponding to the current time spot according to the depth data and the camera pose data;
• generating posed estimated point clouds corresponding to the current time spot according to the camera pose data corresponding to the current time spot and a previous 3D model corresponding to a previous time spot;
• and
• generating a current 3D model of the target object according to the posed 3D point clouds based on a difference between the posed 3D point clouds and the posed estimated point clouds.
