videocameracalibrationmogemapper

Compute the camera intrinsics and field of view (FOV) for a static camera using Moge-2 (more accurate than DeepCalib).

使用 Moge-2（比 DeepCalib 更精确）计算静态相机的内参和视场角（FOV）。

🔧 Parameter Configuration 参数配置

name 参数名	type 类型	default 默认值	desc 说明
model_path	<class 'str'>	'Ruicheng/moge-2-vitl'	The path to the Moge-2 model.
frame_num	typing.Annotated[int, Gt(gt=0)]	3	The number of frames to be extracted uniformly from the video. If it's 1, only the middle frame will be extracted. If it's 2, only the first and the last frames will be extracted. If it's larger than 2, in addition to the first and the last frames, other frames will be extracted uniformly within the video duration. If "duration" > 0, frame_num is the number of frames per segment.
duration	<class 'float'>	0	The duration of each segment in seconds. If 0, frames are extracted from the entire video. If duration > 0, the video is segmented into multiple segments based on duration, and frames are extracted from each segment.
tag_field_name	<class 'str'>	'camera_calibration_moge_tags'	The field name to store the tags. It's "camera_calibration_moge_tags" in default.
frame_dir	<class 'str'>	DATA_JUICER_ASSETS_CACHE	Output directory to save extracted frames.
if_output_info	<class 'bool'>	True	Whether to save the camera parameters results to an JSON file.
output_info_dir	<class 'str'>	DATA_JUICER_ASSETS_CACHE	Output directory for saving camera parameters.
if_output_points_info	<class 'bool'>	True	Determines whether to output point map in OpenCV camera coordinate system (x right, y down, z forward). For MoGe-2, the point map is in metric scale.
if_output_depth_info	<class 'bool'>	True	Determines whether to output depth maps.
if_output_mask_info	<class 'bool'>	True	Determines whether to output a binary mask for valid pixels.
args		''	extra args
kwargs		''	extra args
