Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right with reference to the accompanying drawings and embodiments The synchronous method of NPC systems and device carry out further in a kind of indoor evacuation environment based on virtual reality proposed by the present invention It is described in detail.It should be appreciated that specific embodiment described herein is not intended to limit the present invention only to explain the present invention.
As shown in Figure 1, in a kind of indoor evacuation environment based on virtual reality in one embodiment NPC systems it is same The flow diagram of one step process, specifically includes following steps：
Step 102, the test instruction of user is received, instantiation operation is synchronized to NPC crowd.
Step 104, to the NPC crowd of completion instantiation operation, the calculating for passing through default AI systems of behavior obtains NPC people The coordinate and animation of each personnel in group.
Step 106, judge whether NPC crowd reaches default terminal, if NPC crowd reaches default terminal, NPC crowd is held Row deletes operation clearly.
In the present embodiment, judge whether NPC crowd reaches default terminal and include：When the unlatching of AI systems of behavior, into certainly The NPC crowd of dynamic pathfinding state is judged, judges whether NPC crowd reaches predeterminated position；If NPC crowd does not reach default position It puts, continues to execute automatic seeking dataway operation.
Further, judge whether NPC crowd reaches predeterminated position and include：It, will if NPC crowd reaches predeterminated position NPC crowd switches to waiting vehicle status；To judging into the NPC crowd of waiting vehicle status, judge pre- If whether there is fire behavior information in scope；If fire behavior information is not detected in preset range, the waiting vehicles are continued to execute Operation.It is understood that fire behavior information includes：Fire location information, burning things which may cause a fire disaster strength information and fire behavior developing state information.
Further, judge whether there is fire behavior information to include in preset range：If fire behavior is detected in preset range Information then carries out NPC crowd to run to default export operation；Judge whether NPC crowd runs to default outlet, if it has not, then right NPC crowd, which continues to execute, runs to default export operation, if it has, then judge that NPC crowd completes emergency evacuation test, and to NPC Crowd performs and deletes operation clearly.
In addition, the disclosure further includes：The test data that the NPC crowd for reaching default terminal generates is packaged with Storage.Wherein, test data includes：The measured for being configured binocular vision photographic device examines on the emulation platform built in advance The personal information of survey, personnel's flow of preset range distance, the body position information of personnel, personnel behavior act information and The physiological index information of personnel.
It should be noted that personal information includes：The gender of personnel, the age range of personnel；And preset range distance Personnel's flow include：Personnel activity path of the preset range apart from different directions；And the body position information of personnel includes： The head position data of measured, head is towards data, body position data, and body is towards data and two-hand positions data； And the behavior act information of personnel includes：Standing information, the walking information of personnel and the information of running of personnel of personnel；With And the physiological index information of personnel includes：Heart rate index, dermatopolyneuritis, blood pressure index and body temperature index.
The synchronous method of NPC systems, reception make in a kind of indoor evacuation environment based on virtual reality provided by the invention The test instruction of user, instantiation operation is synchronized to NPC crowd；To completing the NPC crowd of instantiation operation, by default The calculating of AI systems of behavior obtain the coordinate and animation of each personnel in NPC crowd；It is default whole to judge whether NPC crowd reaches Point if NPC crowd reaches default terminal, performs NPC crowd and deletes operation clearly.This method provides a kind of dredging based on virtual reality Dissipate in environment acquisition with analyzing the synchronous method of data, can Real Time Observation personal information, accurately analyze personnel's flow, personnel's Behavior act information, by the data transfer of acquisition to the measured in environment, meanwhile, Synchronization Analysis goes out the conduct route of measured The advantageous effect of preferred path evacuation is quickly and effectively realized in track.Flexibility and ease for use with utilization.
