P2GS: Physical Prior-guided Gaussian Splatting for Photometrically Consistent Urban Reconstruction

3D Gaussian Splatting (3DGS) has recently emerged as a powerful explicit representation enabling fast, high-fidelity rendering, making it a promising foundation for closed-loop simulators and perception models in autonomous driving. However, conventional 3DGS implicitly assumes consistent exposure a
