track error! how can i fix it? #309

Open jcyhcs opened 3 years ago

jcyhcs commented 3 years ago

hi,professor: there is a track error examples,look pictures below: image image image image image image red rectangle is my detector result, green rectangel is tracker result! my tracker setting: image then what can i do? please help!

Mmm.... You can trying to set:

m_trackerSettings.SetDistance(tracking::DistCenters);
m_trackerSettings.m_kalmanType = tracking::KalmanLinear;
m_trackerSettings.m_filterGoal = tracking::FilterRect;
m_trackerSettings.m_lostTrackType = tracking::TrackCSRT;

And another case: m_trackerSettings.m_minAreaRadiusPix = frame.rows / 20.f;

I'll think about visual debug tool for tracking algorithm.

hi,professor:

when i set m_trackerSettings.m_minAreaRadiusPix = h / 20.f; DO NOT WORK! look : image image

i can not set m_trackerSettings.m_lostTrackType = tracking::TrackCSRT;
because i don't have opencv_contirb module! oh, please help me!

Hi!

  1. I'm added debug visualization in assignment solving. Pull the latest changes from this repository. For enabling advanced info in CTracker.cop set: #define DRAW_DBG_ASSIGNMENT 1 Here: https://github.com/Smorodov/Multitarget-tracker/blob/master/src/Tracker/Ctracker.cpp#L143

  2. Set: m_trackerSettings.m_distThres = 0.99f;

  3. Run Multitarget-tracker with -a=0 command line option. You can push 'M' button - manual frame switching by pressing any key on keyboard.

  4. On new window "dbgAssignment" you can see weight and links between tracks and detects.

hi.professor: first ,you visual debug tool i can not use , because i just use your tracker!, and i Integration into my own program,sorry!

i analysis the process,look:[red is my detector!, green is tracker!!] image my detector get two person, and tracker got two assignment , it is right. image my detector lost person 1, got person 0, but tracker also have person 1 , but position not change. image my detector lost two person, there is only tracker rectangle! image my detector got person 1 , lost person 0, LOOK, tracker got person 0 rectangle, but SHIFT! image my detecor lost two person, the tracker person 1 slow shift! image my detector also lost , the tracker also slow shift! image now, my detector got person 1, tracker assignment ERROR!

SO, professor! tracking algorithem has some BUG? kalman filter have some bug? please help!

Hi! I see this bug but I don't see concrete values: distances between tracks and detects. Do you can download latest sources, set DRAW_DBG_ASSIGNMENT 1 in source code and show here screen from new debug window? I want to find problem but I need advanced info

jcyhcs commented 3 years ago

ok,professor: i use your example, i recode screen: please look the video:

Thnx for the advanced info. I see the problem but not all in details. Do you can save all detects to the txt or csv file? With any format, for example: frame_ind_N objects_count left1 top1 width1 height1 left2 top2 width2 height2 frame_ind_N_plus_1 objects_count left1 top1 width1 height1 ...

And I'll create simulation from your detection results for debugging.
