The previous 3D pose and shape estimation methods often suffer from the problem of depth ambiguity. Hence, we present a novel method to reduce the depth ambiguity by explicitly considering the depth of a person’s body surface. The key idea is minimizing the difference between the depth estimated from an input image and the projected depth of a reconstructed 3D mesh. This allows the proposed method to estimate 3D pose and body shape with plausible 3D joint locations. Evaluations show that the proposed method produces more appropriate 3D meshes and reduces both 3D pose and shape estimation errors.
