Use cases

UI

• Default mode is UI. By running ./appa you simply call GUI with default project options. Project options are not stored with project configuration (and there're reasons for that). Equivalent to ./appa --mode=ui
• UI with predefined options. You may specify some options, defined in src/options.cpp. This will overwrite default ones. Examples: ./appa --num_threads=3 or ./appa --mode=ui --descriptor_type=SIFT --shared_calibration

CLI

In CLI mode you must specify which action and with which project to perform. Options:

• ./appa --mode=cli --cli_mode=new --project_name=cli-project --project_path=/projects/ --images_path=/images/dataset0/ --action=reconstruction - creates new project and runs reconstruction.
• ./appa --mode=cli --cli_mode=open --project_path=/projects/cli-project/ --action=reconstruction - opens an existent project and runs reconstruction.
• ./appa --mode=cli --cli_mode=temp --images_path=/images/dataset0/ --action=reconstruction - creates temporary project, performs an action and removes it afterwards. It may be useful to specify --output_path in this mode.

In addition to these basic sets, you may also pass any parameters from src/options.cpp.

• Example:

./appa --mode=cli --cli_mode=temp --images_path=/images/dataset0/ --action=reconstruction --num_threads=4 --max_num_features=5000 --use_camera_intrinsics_prior --match_out_of_core --match_strategy=BruteForce
