int mmdeploy_pose_tracker_default_params(mmdeploy_pose_tracker_param_t *params)

Fill params with default parameters.

Parameters

params – [inout]

Returns

status of the operation

int mmdeploy_pose_tracker_create(mmdeploy_model_t det_model, mmdeploy_model_t pose_model, mmdeploy_context_t context, mmdeploy_pose_tracker_t *pipeline)

Create pose tracker pipeline.

Parameters

• det_model – [in] detection model object, created by mmdeploy_model_create

• pose_model – [in] pose model object

• context – [in] context object describing execution environment (device, profiler, etc…), created by mmdeploy_context_create

• pipeline – [out] handle of the created pipeline

Returns

status of the operation

void mmdeploy_pose_tracker_destroy(mmdeploy_pose_tracker_t pipeline)

Destroy pose tracker pipeline.

Parameters

pipeline – [in]

int mmdeploy_pose_tracker_create_state(mmdeploy_pose_tracker_t pipeline, const mmdeploy_pose_tracker_param_t *params, mmdeploy_pose_tracker_state_t *state)

Create a tracker state handle corresponds to a video stream.

Parameters

• pipeline – [in] handle of a pose tracker pipeline

• params – [in] params for creating the tracker state

• state – [out] handle of the created tracker state

Returns

status of the operation

void mmdeploy_pose_tracker_destroy_state(mmdeploy_pose_tracker_state_t state)

Destroy tracker state.

Parameters

state – [in] handle of the tracker state

int mmdeploy_pose_tracker_apply(mmdeploy_pose_tracker_t pipeline, mmdeploy_pose_tracker_state_t *states, const mmdeploy_mat_t *frames, const int32_t *use_detect, int32_t count, mmdeploy_pose_tracker_target_t **results, int32_t **result_count)

Apply pose tracker pipeline, notice that this function supports batch operation by feeding arrays of size count to states, frames and use_detect.

Parameters

• pipeline – [in] handle of a pose tracker pipeline

• states – [in] tracker states handles, array of size count

• frames – [in] input frames of size count

• use_detect – [in] control the use of detector, array of size count -1: use params.det_interval, 0: don’t use detector, 1: force use detector

• count – [in] batch size

• results – [out] a linear buffer contains the tracked targets of input frames. Should be released by mmdeploy_pose_tracker_release_result

• result_count – [out] a linear buffer of size count contains the number of tracked targets of the frames. Should be released by mmdeploy_pose_tracker_release_result

Returns

status of the operation

void mmdeploy_pose_tracker_release_result(mmdeploy_pose_tracker_target_t *results, const int32_t *result_count, int count)

Release result objects.

Parameters

• results – [in]

• result_count – [in]

• count – [in]
