Start the Project and get your photos oriented
1.Start a PhotoModeler Scanner Points-based project and import your photos.Alternately use an Automatic project if using RAD targets (note the steps below correspond to a Points-based project).
2.Mark the coded targets using the Automatic Target Marking tool in PM Scanner (Marking menu).If you are not using targets,mark and reference your points manually.Ensure your points are accurately marked and properly referenced,and process the project.
3.Check your point mark residuals (see Point Table) and make sure all points have residuals of less than 1.0,which indicates a well-solved model and strong camera orientations.
4.Save the project.
5.Idealize the photos (Project menu / Idealize Project).Reprocess the project.
6.Set your project scale.Setting a scale is not mandatory but it makes it easier to relate to the DSM settings such as sample rate and depth range when they are in real world coordinates.
7.It is usually a good idea to mark a DSM trim to outline and limit the area to be scanned.This will help speed up the DSM process as only the area of interest will be modeled.It will also help reduce noise around the area of interest.Mark a DSM trim on each photo.
You’ll see below that the coded targets are marked and the DSM trim outlines the face,neck and head:
Set your DSM options
1.First,set a low-density sample-rate (ie a large value).You’ll want to make sure your settings are appropriate before doing a full detail DSM.Experimenting with a low-density DSM will help speed up the process of finding the optimal settings as you will spend less time waiting for DSM processing.
2.Keep the default depth range.
3.When modeling a face or a material like skin typically your advanced DSM settings will be:
Sub-pixel:On
Super-sampling factor:2
Matching Region Radius:20
Texture Type:1
4.Run the DSM (without Meshing steps) and check that your model is solving reasonably well and the shape of the face can be discerned from the point cloud (ie not a lot of noise,or large gaps between points).
5.Evaluate your initial DSM.If the DSM has a lot of noise,go to the ‘Adjusting Depth Range and/or Base Surface’ section below.If it looks reasonable,move to the ‘Densify your Point Cloud’ section below.
This looks reasonably close (depth range of +/-25cm):
This looks like a lot of noise (depth range of +/-5cm):
Adjusting Depth Range and/or Base Surface
If your first attempt has a lot of noise,you’ll need to adjust your settings.If you’re confident with your orientations (look for small maxiumum residual as one indicator),the most likely culprit is the depth range setting.A depth range that is too small will not allow PMScanner to find appropriate matches,while one that is too big will also cause problems (esp.true with weak texture we find with human skin).
Adjusting the depth range from +/-5cm to +/-25cm resulted in this improved initial DSM:

启动该项目,并得到您的照片导向
1.启动PhotoModeler扫描点为基础的项目和进口你的照片.交替使用的自动项目如果使用RAD指标（请注意以下步骤对应一个点为基础的项目）.
2.马克的目标,使用自动编码的目标作标记下午扫描器（标记菜单）工具.如果你不使用的目标,标记,并提供您点手动.确保您的积分是准确标记,并适当引用,并处理项目.
3.检查您点大关残差（见点表）,并确保所有问题都小于 1.0残差,这表明一个良好的解决模式和强大的照相机方向.
4.保存该项目.
5.理想化的照片（项目菜单/理想化项目）.重新处理该项目.
6.设置您的项目规模.设置一个规模不是强制性的,但它可以更容易地与诸如取样率和深度范围内的用电需求管理设置,当他们在现实世界中的坐标.
7.它通常是一个好主意,标志着帝斯曼修剪概述和限制该地区进行扫描.这将有助于加快,因为只有在感兴趣的领域,帝斯曼进程将模仿.它也将有助于减少周围噪音方面的利益.马克一帝斯曼修剪每张照片上.
你会看到下面的标记和编码的目标是在帝斯曼修剪轮廓面部,颈部和头部：
设置您的帝斯曼选择
1.首先,设置一个低密度采样率（即一个较大的值）.你会希望确保您的设置之前,做了全面详细的用电适当的.以低密度帝斯曼实验将有助于加快寻找你将花更少的时间等待帝斯曼加工过程中的最佳设置.
2.保持默认的深度范围.
3.当模特儿的脸或皮肤像你的先进典型用电设置将材料：
子像素：在
超级采样系数：2
匹配区域半径：20
结构类型：1
4.运行无啮合步骤帝斯曼（）,并检查你的模型是合理解决好与脸型可以从点云（即不察觉大量的噪音,或点之间的巨大差距）.
5.评估您的初始用电.如果帝斯曼有一个很大的噪音,到'调整深度范围和/或基面'一节.如果它看起来合理,移动到'稠化的点云'一节.
这看起来相当接近（深度范围+ / - 25厘米）：
这看起来像一个噪声（深度范围内大量的+ / - 5厘米）：
调整的深度范围和/或基面
如果您第一次尝试了大量的噪音,您需要调整您的设置.如果你与你的方向（信心寻找小协作者最多的一个指标残余）,最有可能是罪魁祸首,是深度范围设置.一个深度范围太小,不会让PMScanner寻找合适的匹配,而一个是太大也会造成问题（特别是我们薄弱的纹理与真实人体皮肤找到）.
调整从+ / - 5厘米的深度范围为+ / - 25厘米最初帝斯曼在这种改进的结果：
