摄影测量已成为 3D 行业不可或缺的一部分，尤其是在为电影、电视和游戏创建数字角色时。在这个 5.5 小时的工作坊中，经验丰富的高级 3D 艺术家和面部建模师 Adam Spring 对摄影测量进行了深入介绍，重点是使用单相机头部扫描。本次研讨会的主题包括摄影原理、捕捉套件和捕捉头部扫描的拍摄模式；以及用例、示例和所涉及的限制。

Adam 采用游击式方法使用单摄像头头部扫描来捕捉 3D 头部。在他在 Lightroom 中预处理生成的图像之前，展示了他的完整过程。在这个特殊的工作流程中，引入了 Agisoft Metashape 来处理扫描数据，然后才能在 ZBrush 中开始网格清理工作。 Adam 然后分享了他如何使用 Wrap 在 ZBrush 中包装他的自定义拓扑，以及如何使用 Photoshop 和 Mari 的组合去除任何不需要的纹理细节。研讨会的最后一部分探讨了如何将扫描数据优化到可用于任何实体角色外观开发流程的程度。

Photogrammetry has become an integral part of the 3D industry, particularly when it comes to creating digital characters for film, TV, and games. In this 5.5-hour workshop, Adam Spring, an experienced senior 3D artist and facial modeler, provides an in-depth introduction to photogrammetry, with a focus on using single-camera head scanning. The topics included in this workshop cover the principles of photography, capture kits, and shooting patterns for capturing a head scan; as well as use cases, examples, and the limitations involved.

Adam takes a guerrilla approach to capture 3D heads using single-camera head scanning. His complete process is shown before he pre-processes the resulting images in Lightroom. With this particular workflow, Agisoft Metashape is introduced to process the scan data, before the mesh cleanup work can begin in ZBrush. Adam then shares how he wraps his custom topology in ZBrush using Wrap, as well as how to remove any unwanted texture details using a combination of Photoshop and Mari. The final segment of the workshop explores how to optimize scan data to a point where it can be used for any solid character look development pipeline.
