Photogrammetry in Dissimilar Images

Context: Photogrammetry
• with methods like Structure from Motion (SfM) or
Bundle Adjustment (BA)
• takes a sequence of images, e.g., a video stream,
• and computes 3D models from this
Problem:
• runtime can be very long if there are many images
Idea:
• skip images in the video stream that are very “similar” to the previous one
• use, e.g., cross-correlation to determine image “similarity”
