Reconstructing detailed 3D scenes from single-view images remains a challenging task due to limitations in existing approaches, which primarily focus on geometric shape recovery, overlooking object appearances and fine shape details. To address these challenges, we propose a novel framework for simultaneous high-fidelity recovery of object shapes and textures from single-view images. Our approach utilizes the proposed Single-view neural implicit Shape and Radiance field (SSR) representations to leverage both explicit 3D shape supervision and volume rendering of color, depth, and surface normal images. To overcome shape-appearance ambiguity under partial observations, we introduce a two-stage learning curriculum incorporating both 3D and 2D supervisions. A distinctive feature of our framework is its ability to generate fine-grained textured meshes while seamlessly integrating rendering capabilities into the single-view 3D reconstruction model. This integration enables not only improved textured 3D object reconstruction by 27.7% and 11.6% on the 3D-FRONT and Pix3D datasets, respectively, but also supports the rendering of images from novel viewpoints. Beyond individual objects, our approach facilitates composing object-level representations into flexible scene representations, thereby enabling applications such as holistic scene understanding and 3D scene editing. We conduct extensive experiments to demonstrate the effectiveness of our method.

从单视图图像重建详细的3D场景仍然是一项具有挑战性的任务，我们提出了一种新颖的框架，用于从单视图图像中同时高保真地恢复物体形状和纹理。我们的方法利用了提出的单视图神经隐式形状和辐射场(SSR)表示，利用显式的3D形状监督和颜色、深度和表面法线图的体素渲染，克服了部分观测下形状和外观的模糊性，同时支持从新视点渲染图像。除了个体物体，我们的方法还支持将物体水平的表示组合成灵活的场景表示，从而实现了整体场景理解和3D场景编辑等应用。我们进行了大量实验证实了我们方法的有效性。
