-"""
-calibrate.py —— 在跑 OpenMVS 之前，对输入照片做白平衡 + 曝光统一。
-这是消除"源视图色温差异"最彻底、最安全的办法：在像素进入纹理管线之前就对齐。
-用法: python calibrate.py <image_dir> <out_dir>
-
-做了两件事（都可选、都保守，不会破坏细节）：
-1) Gray-World 白平衡：把每张图的通道均值拉向全局中值（去色温差）
-2) 全局曝光归一化：把所有图的亮度中位数对齐到全局中位数（去曝光差）
-
-注意：OpenMVS 的 EstimateGlobalPhotometricCorrection 强依赖稠密点云，
-如果没有点云它会被跳过（你之前日志里 "Photometric: no point cloud, skip"）。
-所以在这里预处理是最稳的兜底。
