Trauma Stress Behavior Detection (Emergency Scene) | 受灾人群心理创伤行为识别（应急场景）

Using fixed cameras in emergency shelters, the system analyzes video of disaster-affected crowds to detect typical acute stress reactions: stupor (prolonged motionless state with no response to external stimulation), tremor (involuntary shaking of body or limbs), unresponsiveness (no orientation or avoidance reaction to calls or sounds), and hypervigilance (frequent scanning of surroundings, startle reactions). When these behaviors are detected, the system outputs a psychological crisis alert to notify on-site psychological-rescue teams to intervene in time, provide emergency psychological support, and help prevent acute stress disorder or post-traumatic stress disorder. Application scenarios: emergency shelters for earthquakes, floods and other natural disasters; wartime air-defense facilities; temporary accident-site resettlement points. The system monitors in real time, displays alerts on command-center screens with location markers, and guides psychological-rescue staff to the site. Skill features: after earthquakes, floods and similar disasters, affected people may develop acute stress disorder; without timely intervention this can progress to PTSD. AI auto-identification of stupor / tremor and other behavioral signals helps rescue teams quickly locate those needing psychological support, improving rescue efficiency and reducing long-term trauma. Can be integrated into emergency command systems or mobile-shelter security devices as an important aid for disaster psychological rescue. | 通过应急避难所内的固定摄像头，分析受灾人群的行为视频，检测急性应激反应下的典型行为：木僵（长时间静止不动，对外界刺激无反应）、颤抖（身体或四肢不自主抖动）、无反应（对呼唤、声响等刺激没有定向或回避反应）以及过度警觉（频繁环顾四周、惊跳反应）。当检测到上述行为时，输出心理危机预警，提示现场心理救援团队及时介入，提供紧急心理支持，预防急性应激障碍或创伤后应激障碍。应用场景：地震、洪水等自然灾害应急避难所、战时防空设施、事故现场临时安置点。系统实时监测，当发现心理创伤行为时，通过指挥中心屏幕预警，并标注位置，引导心理救援人员前往。技能特点：地震、洪水等灾害发生后，受灾人群可能出现急性应激障碍，若不及时干预可能发展为创伤后应激障碍。通过AI自动识别木僵、颤抖等行为信号，可帮助救援团队快速定位需要心理支持的人员，提高救援效率，减少长期心理创伤。该技能可集成到应急指挥系统或移动避难所安防设备中，成为灾害心理救援的重要辅助工具。
