POEM (Point Embedded Multi-view) focuses on reconstructing an articulation body with "true scale" and "accurate pose" from a series of sparsely arranged camera views. In practice, we used the example of hand. POEM explores the power of points, using a cluster of (x, y, z) coordinates with natural positional encoding to find associations in multi-view stereo.

We trained a model to identify the image of staplers(distinguish from mechanical arms as an example). After image recognition, we analyzed the feature information contained in the obtained image to help design. This method can also use in other product designs.
