Photography tips

The following tips will help you take quality photos for photogrammetry:

If you can, take photos in a location where lighting is consistent and doesn't cast shadows.
Try to keep your own shadow out of the picture.
Make sure that there are no moving objects in the background when you take the photos.
If the camera that you're using has a high dynamic range (HDR) setting, turn the feature off, and try not to adjust the exposure of your photographs while you capture images.
Take pictures about one meter apart while you circle the object.
If you can, maintain a perpendicular location relative to the object while you take photos.
If the object is large, move in a lateral motion from one end of it to the other, and change the height at each pass, until you've captured all surfaces.

Set preferences

For the most part, you can use the default preferences. However, there are a few changes that you must make before you start.

On the Tools menu, select Preferences.
In the Metashape Preferences dialog box, on the GPU tab, select the check box for any graphics processing units (GPUs) that are available. If only one GPU is available, select the Use CPU when performing GPU accelerated processing check box at the bottom of the dialog box. When you've finished, select Apply.
On the Advanced tab, in the Miscellaneous section, follow these steps:
1. Select the Enable fine-level subdivision check box. This option produces a more refined model that has more triangles.
2. Select the Enable VBO support check box. This option provides a more refined way of storing the information in the structure of the graphics card memory. The result is a more detailed polygonal model.
3. Select OK to apply your changes and close the Metashape Preferences dialog box.
Note
If the camera that you're using has extensive metadata about location, orientation, and so on, you might also want to experiment with the options in the Export/Import section of the Advanced tab.

Import your photos

After you've finished setting up your preferences, the first step is to import the photos that Metashape will use to construct the 3D model.

On the Workflow menu, select Add Photos, and then select the photos to import.

Mask your photos

You can 'mask out' any irrelevant elements in your source photos that might be confusing to the program or produce undesirable results. By limiting the number of pixels that the application must be aware of, you help reduce the memory profile of each image. The result is a better 3D model. You might want to complete this step from different angles in your photos. Although you don't have to mask objects in every photo, the more photographs you mask, the more accurate the result will be.

Double-click an image to open it, and then select a selection tool, such as Intelligent Scissors.
Outline your 3D model subject, and then select Add Selection to create the mask.
Your model should now resemble the following illustration.
For the best results, repeat this procedure in multiple photos, from multiple angles.

Align the photos

Photogrammetry uses objects that are consistently present in multiple images to create a map of where it thinks the camera was when the photo was taken. For this step of the process, you use the Align photos command.

On the Workflow menu, select Align Photos.
In the Align Photos dialog box, use the default settings (see the following illustration), or change the settings as you require. When you've finished, select OK.
Select the Model menu to view the results. Your model should now resemble the following illustration.

Align the region

After you've finished aligning the photos, you can use the bounding box to trim the size of your 3D object.

This step isn't required, but it speeds up the next steps.

On the toolbar, select the Resize Region tool.
Drag the spheres at the edge of the region to select the area that you want to convert.

Build a dense point cloud

The next step is to generate a point cloud. You can then use the point cloud to generate polygonal data that is used to form a mesh. By increasing the number of points that are generated from the aligned photos, you help define an accurate 3D representation of the surface.

On the Workflow menu, select Build Dense Cloud.
In the Build Dense Cloud dialog box, use the following settings:
- Quality: Select Medium.
  Note
  If you have a powerful computer, you can set the Quality field to High. However, for many operations, the Medium setting produces quality results.
- Deep filtering: Select Aggressive.
- Calculate point colors: Select the check box.
These settings are good settings to start from. Experiment with other options to see the different results that they produce. Your results might vary, depending on the subject matter and surface characteristics of the object that you're working with.
When you've finished, select OK.

Build the mesh
