Gets the path tracking results of a Amazon Rekognition Video analysis started by
StartPersonTracking.
The person path tracking operation is started by a call to
StartPersonTracking which returns a job identifier (
JobId). When the operation finishes, Amazon Rekognition Video publishes a completion status to the Amazon Simple Notification Service topic registered in the initial call to
StartPersonTracking.
To get the results of the person path tracking operation, first check that the status value published to the Amazon SNS topic is
SUCCEEDED. If so, call
GetPersonTracking and pass the job identifier (
JobId) from the initial call to
StartPersonTracking.
GetPersonTracking returns an array,
Persons, of tracked persons and the time(s) their paths were tracked in the video.
GetPersonTracking only returns the default facial attributes (
BoundingBox,
Confidence,
Landmarks,
Pose, and
Quality). The other facial attributes listed in the
Face object of the following response syntax are not returned.
For more information, see FaceDetail in the Amazon Rekognition Developer Guide.
By default, the array is sorted by the time(s) a person's path is tracked in the video. You can sort by tracked persons by specifying
INDEX for the
SortBy input parameter.
Use the
MaxResults parameter to limit the number of items returned. If there are more results than specified in
MaxResults, the value of
NextToken in the operation response contains a pagination token for getting the next set of results. To get the next page of results, call
GetPersonTracking and populate the
NextToken request parameter with the token value returned from the previous call to
GetPersonTracking.
In the AWS.Tools.Rekognition module, this cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.
