Cannot identify the same person across different views at the same time? 無法同時從不同視角辨識同一個人？

I tried to reproduce your results, but found that I couldn't identify the same person from different perspectives. Here is the output file and visualization of the results.
我嘗試重現你們的結果，但是發現無法從不同視角辨識同一個人，以下是輸出文件和視覺化的結果。

You can see that the track IDs of different perspectives are different. I don't know what the problem is. Please help me.
可以看到不同視角的track id是不一樣的，我不知道哪個環節出問題了。請幫幫我

But tracking at different times is no problem
但是不同時間的追蹤是沒問題的
