How to draw a tracing line?

[VYRION-Ai]

hi @Jacobsolawetz and @maxhs2014 i want to draw a tracing line for the object , how i can i do that?

[Jacobsolawetz]

Hello @totoadel we don’t currently have that visualization but it would be cool to add it. Do you have an example video of what you’re looking for? And how many frames back does the tracing line follow?

[VYRION-Ai]

yes like what happened here in this video. https://www.youtube.com/watch?v=Cu3ERM0Zk4s and all frames the object are still founded.

Ok cool - thanks for the example, we will put it on the list of todo

If you want to try a PR, it would be maintaining a dictionary for each object with history of box center locations, then plotting that line at visualization time

than you very much @Jacobsolawetz

i did it thank you very much. @Jacobsolawetz
this is the code

height, width, _ = im0.shape
                        x1, y1, x2, y2 = max(0, int(bboxes[0])), max(0, int(bboxes[1])), min(width,
                                                                                             int(bboxes[2])), min(
 height, int(bboxes[3]))
 center = (int((x1 + x2) / 2), int((y1 + y2) / 2))
 chk = checkKey_track(id_track, (id))
  if chk == 1:
            resl=all_values(id_track, id)
            for key in list (resl):
                        cv2.circle(im0, resl[key], radius=5, color=color, thickness=-1)
                         upd_dict = {(count_id): center}
                         id_track[(id)].update(upd_dict)
 else:
           upd_dict = {(count_id): center}
            id_track[(id)]=(upd_dict)

def checkKey_track(dict, key):
    if key in dict.keys():
        return 1
    else:
        return 0

def all_values(dict_obj,ids):
 for p_id, p_info in dict_obj.items():
    if ids == p_id:
        for key in p_info:
            p_info[key]
 return p_info

Nice! Can you post an example video?

[Jacobsolawetz]

@maxhs2014, let's take a look this week together

let me upload video to you tube
