静态代码检测
在DeepSORT中,判断目标是否静止的代码如下所示:
```python
def is_still(self, t: Track) -> bool:
"""
Judge whether the tracked object is still or not.
Args:
t: a track object
Returns:
A bool value indicating whether the tracked object is still or not.
"""
if len(t.trace) <= 1:
return True
else:
# calculate the mean velocity of the track
mean_v = np.mean(np.diff(np.array(t.trace), axis=0), axis=0)
# if the mean velocity is below a threshold, the object is considered still
if np.linalg.norm(mean_v) < self.still_thresh:
return True
else:
return False
```
在这里,我们首先检查跟踪对象的轨迹长度是否小于等于1,如果是,则认为对象是静止的。否则,我们计算跟踪对象的平均速度,并检查其是否低于静止阈值。如果是,则认为对象是静止的,否则就认为对象是移动的。
