Abstract
The present disclosure relates to a method and system for three-dimensional reconstruction, and a storage medium. Embodiments regarding three-dimensional reconstruction are described. In an embodiment, the method for three-dimensional reconstruction comprises: obtaining a composite image obtained by photographing a body of a target object and a mirror image of the target object; and performing three-dimensional reconstruction on the target object by using the composite image and relative position and posture information representing a position and posture of a mirror for generating the mirror image relative to a camera for the photography.
Claims11
A method for three-dimensional reconstruction, comprising:
- obtaining a composite image obtained by photographing a body of a target object and a mirror image of the target object;
- and
- performing three-dimensional reconstruction on the target object by using the composite image and relative position and posture information representing a position and posture of a mirror for generating the mirror image relative to a camera for the photography, wherein the performing three-dimensional reconstruction comprises
- performing random sampling on points within a given three-dimensional space comprising the target object;
- extracting a global feature corresponding to a sampling point from the composite image;
- performing encoding on imaging-related geometric information of the sampling point, to generate geometric encoded information;
- and
- inputting the global feature and the geometric encoded information into a model, to determine a geometric relationship between the sampling point and a surface of the target object.
An electronic device, comprising:
- a memory;
- and
- a processor coupled to the memory, the processor being configured to perform, based on instructions stored in the memory, the steps of:
- obtaining a composite image obtained by photographing a body of a target object and a mirror image of the target object;
- and
- performing three-dimensional reconstruction on the target object by using the composite image and relative position and posture information representing a position and posture of a mirror for generating the mirror image relative to a camera for the photography, wherein the performing three-dimensional reconstruction comprises
- performing random sampling on points within a given three-dimensional space comprising the target object;
- extracting a global feature corresponding to a sampling point from the composite image;
- performing encoding on imaging-related geometric information of the sampling point, to generate geometric encoded information;
- and
- inputting the global feature and the geometric encoded information into a model, to determine a geometric relationship between the sampling point and a surface of the target object.
