[QUESTION] How to use GPU? #15

Closed ichsan2895 closed 1 month ago

ichsan2895 commented 1 month ago

Is it possible for using GPU acceleration when running this command?

glomap mapper --database_path DATABASE_PATH --output_path OUTPUT_PATH --image_path IMAGE_PATH

FYI, I have built from source colmap 3.9.1 and glomap with ceres-2.1.0 & CMake 3.28.4. Tested on Ubuntu 22.04.3 LTS.

Usage:
  glomap mapper --database_path DATABASE --output_path MODEL
  glomap mapper_resume --input_path MODEL_INPUT --output_path MODEL_OUTPUT
Available commands:
  help
  mapper
  mapper_resume

Hi, so far, GLOMAP does not support GPU acceleration
