hi ,@AlexeyAB In project yolo _console_dll , same car has two different object_id. just like in the picture. it makes more difficult for tracking. it there any way to solve this problem?

@pingan1369 hi,

What model do you use?
Can you compress and attach your files yolo.cfg and obj.names?

@AlexeyAB hi

Thanks for the quick response!

1 i am using yolov3.cfg and yolov3.weights (download form https://pjreddie.com/media/files/yolov3.weights)

2 object names come from the file : data/coco.names

i only change the number of frame_story and max_dist.

So car is detected as 2 objects: Car and Truck.

May be this is just false-positive of Yolo v3 model. Try to set width=608 height=608 in yolov3.cfg

@AlexeyAB
hi, thanks for your reply

it seems no improvement after setting width=608 height=608 in yolov3.cfg.
i am confused about the codes : https://github.com/AlexeyAB/darknet/blob/fb1ee79576f83d505211267252e070c3cb0f431e/src/yolo_v2_class.cpp#L360 The track_id in cur_bbox_vec is 0 and track_id_absent must be true. what are the codes working for?
how can i get the missing number of a object in functon Detector::tracking_id (....)? it seems frame_story is not the missing number.
