drawing bbox

[SaddamBInSyed]

Hi I have tried the below code to draw bbox around hand but not drawing properly

(handtracker.py)

bounding box offsets, width and height

    dx, dy, w, h = candidate_detect[box_ids, :4]

bbox_dict = {
"x": dx,
"y": dy,
"w": w,
"h": h
}
cv2.rectangle(frame, (bbox_dict['x'], bbox_dict['y']),
(bbox_dict['x'] + bbox_dict['w'], bbox_dict['y'] + bbox_dict['h']), (0, 255, 0), 1)

please advise

hi,SaddamBInSyed

you can modify the code in "run.py" like this :
points, _ = detector(image) -> points, bbox = detector(image)

then ,draw bbox ：

if bbox is not None:
    bbox_pt = np.array(bbox ,dtype=np.int)
    bbox_pt = np.reshape(bbox_pt,(-1,4,2))
    cv2.polylines(frame,bbox_pt,1,POINT_COLOR,THICKNESS)

Hi @patrickwf your code works, could you tell me how can we use the bx, by, w and h provided by the model to draw bounding box ? Also I am not able to understand why do we need to use anchors.csv file.
