Model codes and data for ``Low-cost High-Speed Photogrammetry for Measuring Dynamic Flow Deposits

The dataset contains the raw and processed data of the experiment, and the Matlab code is used to synchronize the cameras. The content includes: 1. CatchFlashlights.m: Matlab algorithm to identify flashlight time steps for camera synchronization.2. cameras_01_10.rar, cameras_11_20.rar, ..., cameras_61_70.rar: videos for the experiment, including calibration, flashlights, and fan evolution for the 70 cameras.3. targets.txt: xyz data for 100 reference points.4. DEM_tif_600_699.rar, DEM_tif_700_799.rar, and DEM_tif_800_900.rar: DEMs for every second during 600-900 seconds for the debris flow fan experiment described in the manuscript.
