System and method for 3D object reconstruction using neural networks

According to some embodiments, there is provided a method for determining a correspondence between a projection pattern and an image of the projection pattern irradiated onto a surface of an object. The method includes obtaining an image of an object while irradiating a projection pattern on a surface of the object. The method further includes outputting, using a neural network, a correspondence between respective pixels in the image and coordinates of the projection pattern. The method further includes reconstructing a shape of the surface of the object using the correspondence between respective pixels in the image and coordinates of the projection pattern. 根据一些实施例，提供了一种用于确定投影图案与照射到物体的表面上的所述投影图案的图像之间的对应关系的方法。所述方法包括在物体的表面上照射投影图案的同时获得所述物体的图像。所述方法还包括使用神经网络来输出所述图像中的相应像素与所述投影图案的坐标之间的对应关系。所述方法还包括使用所述图像中的相应像素与所述投影图案的坐标之间的所述对应关系，重建所述物体的所述表面的形状。
