Field Documentation

◆ base_meta

NvDsBaseMeta _NvDsObjectMeta::base_meta

Definition at line 366 of file sources/includes/nvdsmeta.h.

◆ class_id

gint _NvDsObjectMeta::class_id

Holds the index of the object class inferred by the primary detector/classifier.

Definition at line 375 of file sources/includes/nvdsmeta.h.

◆ classifier_meta_list

NvDsClassifierMetaList * _NvDsObjectMeta::classifier_meta_list

Holds a pointer to a list of pointers of type NvDsClassifierMeta.

Definition at line 411 of file sources/includes/nvdsmeta.h.

◆ confidence

gfloat _NvDsObjectMeta::confidence

Holds a confidence value for the object, set by the inference component.

confidence will be set to -0.1, if "Group Rectangles" mode of clustering is chosen since the algorithm does not preserve confidence values. Also, for objects found by tracker and not inference component, confidence will be set to -0.1

Definition at line 390 of file sources/includes/nvdsmeta.h.

◆ detector_bbox_info

NvDsComp_BboxInfo _NvDsObjectMeta::detector_bbox_info

Holds a structure containing bounding box parameters of the object when detected by detector.

Definition at line 381 of file sources/includes/nvdsmeta.h.

◆ mask_params

NvOSD_MaskParams _NvDsObjectMeta::mask_params

Holds mask parameters for the object.

This mask is overlayed on object

See also: NvOSD_MaskParams.

Definition at line 404 of file sources/includes/nvdsmeta.h.

◆ misc_obj_info

gint64 _NvDsObjectMeta::misc_obj_info

Holds additional user-defined object information.

Definition at line 415 of file sources/includes/nvdsmeta.h.

◆ obj_label

gchar _NvDsObjectMeta::obj_label

Holds a string describing the class of the detected object.

Definition at line 409 of file sources/includes/nvdsmeta.h.

◆ obj_user_meta_list

NvDsUserMetaList * _NvDsObjectMeta::obj_user_meta_list

Holds a pointer to a list of pointers of type NvDsUserMeta.

Definition at line 413 of file sources/includes/nvdsmeta.h.

◆ object_id

guint64 _NvDsObjectMeta::object_id

Holds a unique ID for tracking the object.

UNTRACKED_OBJECT_ID indicates that the object has not been tracked.

Definition at line 378 of file sources/includes/nvdsmeta.h.

◆ parent

struct _NvDsObjectMeta * _NvDsObjectMeta::parent

Holds a pointer to the parent NvDsObjectMeta.

Set to NULL if no parent exists.

Definition at line 369 of file sources/includes/nvdsmeta.h.

◆ rect_params

NvOSD_RectParams _NvDsObjectMeta::rect_params

Holds a structure containing positional parameters of the object processed by the last component that updates it in the pipeline.

e.g. If the tracker component is after the detector component in the pipeline then positinal parameters are from tracker component. Positional parameters are clipped so that they do not fall outside frame boundary. Can also be used to overlay borders or semi-transparent boxes on objects.
