🔧 Parameter Configuration 参数配置¶

name 参数名	type 类型	default 默认值	desc 说明
`tag_field_name`	<class ‘str’>	`'video_camera_pose_tags'`	The field name to store the tags. It’s “video_camera_pose_tags” in default.
`frame_field`	<class ‘str’>	`'video_frames'`	The field name where the video frames are stored.
`camera_calibration_field`	<class ‘str’>	`'camera_calibration'`	The field name where the camera calibration info is stored.
`max_frames`	<class ‘int’>	`1000`	Maximum number of frames to save.
`droid_buffer`	<class ‘int’>	`1024`	DROID SLAM pre-allocated frame buffer size. Controls GPU memory usage — each buffer slot pre-allocates correlation volumes on GPU. Default 1024, sufficient for clips up to ~100 frames. Reduce for shorter clips to save VRAM, increase for longer videos.
`save_dir`	<class ‘str’>	`None`	Directory to save large numpy arrays (depth, cam_c2w) as .npy files instead of storing them inline. When set, tag_dict stores file paths (strings) instead of numpy arrays, which avoids memory limit.
`use_prepare_env`	<class ‘bool’>	`False`	Whether to prepare the environment.
`args`		``	extra args
`kwargs`		``	extra args
