Data for Wire Arc Additive Manufacturing Video Dataset (WAAM-ViD)

WAAM-ViD Dataset - Data and Variables Description Variable List (with full names and definitions): Video_filepath: File path to the video corresponding to each data row. Format: Text (file path) Camera_Matrix: Flattened intrinsic matrix (3x3) describing the internal camera parameters. Format: Numeric list (9 values) Distortion_Coefficients: Flattened vector describing radial and tangential lens distortion coefficients. Format: Numeric list (typically 5 values) Rotation_Matrix: Flattened 3x3 matrix describing camera orientation relative to the world coordinate system. Format: Numeric list (9 values) Translation_Vector: Flattened 3x1 vector describing camera position in the world coordinate system. Format: Numeric list (3 values) External_Light: Indicator whether an external light source was used in the recording. Format: Binary (1 = yes, 0 = no) Travel_Speed: Speed of the welding arm movement during recording. Units: mm/s Current: Electrical current applied during welding. Units: Amperes (A) Width: Width of the weld bead measured at each frame, aligned temporally with the video. Units: mm; if unmeasured, recorded as 0.0 Frame_Annotation (Train/Test): Ground truth segmentation mask per frame (if available), stored separately in folders. Format: PNG or JPEG image files Units of Measurement: Travel speed: millimeters per second (mm/s) Current: amperes (A) Weld bead width: millimeters (mm) Calibration matrices: unitless numeric values Definitions for Missing Data: Width = 0.0: No measurement recorded, typically during initial stationary frames (~first 40 frames) Other metadata fields: Empty or null if unrecorded Specialized Formats / Abbreviations: Cameras: XVC-1000: Xiris XVC-1000 passive HDR camera C400-H: CAVITAR C400-H laser-illuminated active camera File naming convention: Videos are labeled by orientation and camera type (e.g., TopCentral_XVC1000_001.mp4) Column Headings (for metadata CSV): Video_filepath, Camera_Matrix, Distortion_Coefficients, Rotation_Matrix, Translation_Vector, External_Light, Travel_Speed, Current, Width
