image_pts

[oladayosolomon]

Thank for sharing this peice on head pose extimation. pls i am getting this error while trying to replicate this: After running from the begining to that portion of the code i have that error.
def get_head_pose(shape):
image_pts = np.float32([shape[17], shape[21], shape[22], shape[26], shape[36],
shape[39], shape[42], shape[45], shape[31], shape[35],
shape[48], shape[54], shape[57], shape[8]])
_, rotation_vec, translation_vec = cv2.solvePnP(object_pts, image_pts, cam_matrix, dist_coeffs)

NameError Traceback (most recent call last)
in
----> 1 _, rotation_vec, translation_vec = cv2.solvePnP(object_pts, image_pts, cam_matrix, dist_coeffs)

NameError: name 'image_pts' is not defined

pls any solution
