int mmdeploy_detector_create(mmdeploy_model_t model, const char *device_name, int device_id, mmdeploy_detector_t *detector)¶

Create detector’s handle.

Parameters

model – [in] an instance of mmdetection sdk model created by mmdeploy_model_create_by_path or mmdeploy_model_create in model.h
device_name – [in] name of device, such as “cpu”, “cuda”, etc.
device_id – [in] id of device.
detector – [out] instance of a detector

Returns

status of creating detector’s handle

int mmdeploy_detector_create_by_path(const char *model_path, const char *device_name, int device_id, mmdeploy_detector_t *detector)¶

Create detector’s handle.

Parameters

model_path – [in] path of mmdetection sdk model exported by mmdeploy model converter
device_name – [in] name of device, such as “cpu”, “cuda”, etc.
device_id – [in] id of device.
detector – [out] instance of a detector

Returns

status of creating detector’s handle

int mmdeploy_detector_apply(mmdeploy_detector_t detector, const mmdeploy_mat_t *mats, int mat_count, mmdeploy_detection_t **results, int **result_count)¶

Apply detector to batch images and get their inference results.

Parameters

detector – [in] detector’s handle created by mmdeploy_detector_create_by_path
mats – [in] a batch of images
mat_count – [in] number of images in the batch
results – [out] a linear buffer to save detection results of each image. It must be released by mmdeploy_detector_release_result
result_count – [out] a linear buffer with length being mat_count to save the number of detection results of each image. And it must be released by mmdeploy_detector_release_result

Returns

status of inference

void mmdeploy_detector_release_result(mmdeploy_detection_t *results, const int *result_count, int count)¶

Release the inference result buffer created by mmdeploy_detector_apply.

Parameters

results – [in] detection results buffer
result_count – [in] results size buffer
count – [in] length of result_count

void mmdeploy_detector_destroy(mmdeploy_detector_t detector)¶

Destroy detector’s handle.

Parameters: detector – [in] detector’s handle created by mmdeploy_detector_create_by_path

int mmdeploy_detector_create_v2(mmdeploy_model_t model, mmdeploy_context_t context, mmdeploy_detector_t *detector)¶: Same as mmdeploy_detector_create, but allows to control execution context of tasks via context.

int mmdeploy_detector_create_input(const mmdeploy_mat_t *mats, int mat_count, mmdeploy_value_t *input)¶

Pack detector inputs into mmdeploy_value_t.

Parameters

mats – [in] a batch of images
mat_count – [in] number of images in the batch

Returns

the created value

int mmdeploy_detector_apply_v2(mmdeploy_detector_t detector, mmdeploy_value_t input, mmdeploy_value_t *output)¶: Same as mmdeploy_detector_apply, but input and output are packed in mmdeploy_value_t.

int mmdeploy_detector_apply_async(mmdeploy_detector_t detector, mmdeploy_sender_t input, mmdeploy_sender_t *output)¶

Apply detector asynchronously.

Parameters

detector – [in] handle to the detector
input – [in] input sender

Returns

output sender

int mmdeploy_detector_get_result(mmdeploy_value_t output, mmdeploy_detection_t **results, int **result_count)¶

Unpack detector output from a mmdeploy_value_t.

Parameters

output – [in] output obtained by applying a detector
results – [out] a linear buffer to save detection results of each image. It must be released by mmdeploy_detector_release_result
result_count – [out] a linear buffer with length number of input images to save the number of detection results of each image. Must be released by mmdeploy_detector_release_result

Returns

status of the operation
