关于calib矩阵的一些问题

3

您好，最近刚入门这个方向，在看PIFu的时候发现了您的仓库，有一些相关的问题想请教一下： （1）在PIFu的[TrainDataset.py](https://github.com/shunsukesaito/PIFu/blob/f0a9c99ef887e1eb360e865a87aa5f166231980e/lib/data/TrainDataset.py#L139)中，从生成的PARAM中提取出了ortho_ratio、scale、center参数，并利用这些参数计算得到了scale_intrinsic、uv_intrinsic，并最终算出了calib这样一个变换矩阵，但我并不是很懂calib的含义以及这个变换的过程，请您指点一下，或是能否给一些参考链接我去学习一下。 （2）第二个问题与（1）也有些相关，是在[HGPIFuNet.py](https://github.com/shunsukesaito/PIFu/blob/f0a9c99ef887e1eb360e865a87aa5f166231980e/lib/model/HGPIFuNet.py#L85)中，为什么某一个三维坐标值通过calib矩阵做投影之后，得到的z坐标值就是对应该点的深度值？ 希望得到您的回复。

Hi, in Demo there is a missing command line to run the demo: "Use following command to reconstruct the model:" --> missing command below this line.
