PoseEstimation

class PoseEstimation(model_id)

Find poses within an image.

Typical usage:

pose_estimator = edgeiq.PoseEstimation("alwaysai/human-pose")
pose_estimator.load(
        engine=edgeiq.Engine.DNN_OPENVINO,
        accelerator=edgeiq.Accelerator.MYRIAD)

<get image>
results = pose_estimator.estimate(image)

for ind, pose in enumerate(results.poses):
            print('Person {}'.format(ind))
            print('-'*10)
            print('Key Points:')
            for key_point in pose.key_points:
                print(str(key_point))
image = results.draw_poses(image)

Parameters

model_id (string) – The ID of the model you want to use for pose estimation.

estimate(image)

Estimate poses within the specified image.

Parameters

image (numpy array of image) – The image to analyze.

Returns

HumanPoseResult

property accelerator

The accelerator being used.

Type

string

property colors

The auto-generated colors for the loaded model.

Note: Initialized to None when the model doesn’t have any labels. Note: To update, the new colors list must be same length as the label list.

Type

list of (B, G, R) tuples.

property engine

The engine being used.

Type

string

property labels

The labels for the loaded model.

Note: Initialized to None when the model doesn’t have any labels.

Type

list of strings.

load(engine=<Engine.DNN: 'DNN'>, accelerator=<Accelerator.DEFAULT: 'DEFAULT'>)

Initialize the inference engine and accelerator.

Parameters

• engine (Engine) – The inference engine to use.

• accelerator (Accelerator) – The hardware accelerator on which to run the inference engine.

property model_id

The ID of the loaded model.
