Wherein, the concrete mode that terminal calculates the distance between this barrier with this camera head according to this second time span can be: terminal uses the distance computation rule obtained in advance to calculate distance corresponding to this second time span.
For example, this distance computation rule can be: propagation velocity/2 of distance the=the second time span * detection signal, namely when the second time span is 0.01 nanosecond (0.01 nanosecond=0.01*10
-9second), the propagation velocity of detection signal is 3*10
8during meter per second, the distance between barrier and this camera head is just 0.15 centimetre of ((0.01*10
-9second * 3*10
0meter per second)/2=0.15*10
-2rice=0.15 centimetre), therefore terminal can judge that this distance is in the scope of predeterminable range 5 centimetres, and therefore terminal can determine within the scope of predeterminable range, there is the barrier blocking this camera head.
