However, current methods require numerous views to reconstruct a dynamic person and only achieve good performance when only a single person is present in the video. This paper aims to reconstruct a multi-person scene with fewer views, especially addressing the occlusion and interaction problems that appear in the multi-person scene. We propose MP-NeRF, a practical method for multiperson novel view synthesis from sparse cameras without the pre-scanned template human models. We apply a multi-person SMPL template as the identity and human motion prior. Then we build a global latent code to integrate the relative observations among multiple people, so we could represent multiple dynamic people into multiple neural radiance representations from sparse views. Experiments on multi-person dataset MVMP show that our method is superior to other state-of-the-art methods.10.1111/cgf.14646317-3259 pages
