Solution to prevent Trackers targets from obscuring ID switching
Trackers may have problems with ID switching when the target is briefly obscured. To fix this issue you can:
- Adjusting tracking parameters: Enlargement
max_agecap (a poem)track_bufferparameter that allows the tracker to continue to maintain target memory for a number of frames that are obscured. - Trajectory prediction: Enable re-recognition feature caching and trajectory prediction in algorithms such as DeepSORT.
- Multi-feature fusion: In addition to the detection frame, auxiliary information such as target HSV color characteristics can be added.
- Scene Optimization: Consider increasing the number or angle of cameras in application scenarios where there may be occlusion.
For critical applications, it is recommended to use DeepSORT instead of SORT because DeepSORT combined with appearance features is more robust for handling short-term occlusions. Also the detection model can be trained with data augmentation to better handle partial occlusion situations.
