Capturing

If this is the first time you are using photogrammetry software, read the following chapter on how to take good photos for your project.

Basics

• Your scene/object should be well lit.

• Avoid shadows, reflections, and transparent objects.

• Take the photos in diffuse or indirect lighting, such as on an overcast day (outdoor) or using multiple light sources (indoor).

• Don’t use the flash setting on the camera.

• Do not change the focal length/zoom while shooting. Use a fixed focal length lens if possible.

• Try to take pictures from all angles.

• Avoid moving objects in the scene or background.

• If taking pictures using a rotating rig, make sure to use a plain color background with no distinguishable features.

• The object of interest should always fill most of the image.

• Take images with a side overlap of 60% minimum and frontal overlap of 80% minimum.

• For each shot, move to a new position (or rotate the object).

• Do not take multiple images from the same spot.

• For better coverage, you can photograph an area multiple times in different acquisition patterns.

• Avoid shaky, blurry, or warped images.

• The more images you have, the better. You can always filter out repetitive or poor quality images to reduce processing time.
