Typedef Documentation

typedef struct NvDsCoordinate NvDsCoordinate

Hold a coordinate's position.

typedef struct _NvDsEvent NvDsEvent

Holds event information.

typedef struct NvDsEventMsgMeta NvDsEventMsgMeta

Holds event message meta data.

You can attach various types of objects (vehicle, person, face, etc.) to an event by setting a pointer to the object in extMsg.

Similarly, you can attach a custom object to an event by setting a pointer to the object in extMsg. A custom object must be handled by the metadata parsing module accordingly.

typedef enum NvDsEventType NvDsEventType

Defines event type flags.

typedef struct NvDsFaceObject NvDsFaceObject

Holds a face object's parameters.

typedef struct NvDsFaceObjectWithExt NvDsFaceObjectExt

Holds a face object's parameters.

typedef struct NvDsGeoLocation NvDsGeoLocation

Holds geolocation parameters.

typedef struct NvDsObjectSignature NvDsObjectSignature

Holds an object's signature.

typedef enum NvDsObjectType NvDsObjectType

Defines object type flags.

typedef struct NvDsPayload NvDsPayload

Holds payload metadata.

typedef enum NvDsPayloadType NvDsPayloadType

Defines payload type flags.

typedef struct NvDsPersonObject NvDsPersonObject

Holds a person object's parameters.

typedef struct NvDsPersonObjectExt NvDsPersonObjectExt

Holds a person object's parameters.

typedef struct NvDsRect NvDsRect

Holds a rectangle's position and size.

typedef struct NvDsVehicleObject NvDsVehicleObject

Holds a vehicle object's parameters.

typedef struct NvDsVehicleObjectExt NvDsVehicleObjectExt

Holds a vehicle object's parameters.
