How to share lost track buffers across cameras for ReID?

[AngelaYZhang]

I've looked into #129 and #157 and managed to run two instances on jetson nano independently using multiprocessing.
I would like the person to be re-identified again across cameras (the cameras have non-overlapping view, so they will disappear from one cam and appear in another). Currently I've only figured out self.hist_tracks is needed, what other lost track buffers should I share?

Also what is a good approach for sharing the variables with self.hist_tracks an OrderedDict. I've tried using multiprocessing.Manager and converting the ordered dict to list when passing; multiprocessing.Queue but haven't succeeded so far.

Many thanks for any help!

@angelazha 不知道你成功了没有呢，我最近也打算尝试一下你的思路，可以交流一下，1215533585，这是我的QQ。我认为可以利用单摄像头进行跟踪，把特征和crop图等信息放到一个具有datbase概念的队列中，在另外的一个进程中进行消费处理，可以是聚类或者其他有效的方法。
