How to remove specific images / cameras from colmap 3D Poincloud | Clean Colmap


How can i remove already registered images/ cameras from colmap 3D Pointcloud. When i run Colmap to reconstruct a 3D Scene i get the following folder output: database.db, sparse >> 0 >> cameras.bin, images.bin and points3D.bin. I tied to remove a incorrectly registered camera by deleting it inside colmap and then exporting the Model, this doesnt work. I also tried to remove the images index inside the database.db file which didnt worked. I Think the camera/image data is sotred inside the images.bin file. How can i remove specific camera views inside this file?


Solution

  • The images / camera poses are stored in the images.txt file and can just be deleted, make sure to also remove the points2D (also stored inside the images.txt) dataset for each removed image otherwise the file will not be work with colmap.
