Example 2

On the basis of embodiment 1, in this embodiment the second barrier section 2 has a length which is greater than the first barrier section 1. Since the second barrier gate section 2 is rotatable in an emergency state, the second barrier gate section 2 is set to have a length longer than that of the first barrier gate section 1, so that the anti-collision barrier gate can directly collide with the second barrier gate section 2 when an external force collides, thereby realizing anti-collision.

Wherein,,

Z＝b*f/|XR-XT|

taking a depth threshold as a safe distance, taking an average value of depth values of all points in a target frame as an actual depth of the target from the position of the imaging device 14 after depth calculation.
