Description
Technical field
The present invention relates to danger stage field more particularly to a kind of danger stage security systems based on image recognition
System.
Background technique
Some children preference danger stage or danger arenas in, contact with spectators and caused by safety accident hair
Raw quantity increases considerably.On the one hand its reason is that can not be linked up in advance with danger, be on the other hand danger
Controllability is poor, more it is essential that contact of the danger with spectators be not only possible that spectators' body and mind is impacted and injured, to danger
Dangerous object itself may also adversely affect.
In the prior art, in order to avoid the generation of above-mentioned accident, performance side is usually used artificial mode, tells danger in advance
The person of raising and train of dangerous object reduces the contact with spectators to the greatest extent in performance, is retained in safety zone is performed as far as possible, meanwhile, such as
Fruit discovery danger do not listen instruction, i.e., when will be contacted with front-seat spectators, send immediately backup person rush towards front row to danger into
Row is contained and is driven, under emergency situation, it might even be possible to take extreme measures.It will be apparent that above-mentioned expulsion mode is not ideal enough, and
It can not determine that eviction scheme, the efficiency of expulsion are very low according to types of threat objects.Meanwhile danger stage or danger in the prior art
In dangerous object arenas, the control mode simple coarse of the equipment including lifting frame, bias light or draw curtain can not be according to the tool of equipment
