Abstract: Systems and methods are disclosed for reliably detecting gunfire in enclosed spaces having significant acoustic reverberation. Implementations are configured to quickly and reliably report the room or portion of a room where gunfire is located. Innovations herein may ensure low false alarm rate by thresholding, pattern recognition and/or detecting the muzzle optical flash. In some embodiments, a review center with trained personnel may evaluate the incident before reporting to local authorities. The indoor system can be incorporated into an outdoor gunshot location system to better protect a local area such as a campus or a transportation hub. Systems and methods herein may involve features and functionality associated with additional resources, such as intercoms, cellphones, and access control, to provide mitigation of harm in case of a shooting.

Abstract translation: 公开了用于可靠地检测具有显着声学混响的封闭空间中的枪声的系统和方法。 配置实施能够快速，可靠地报告枪支所在的房间或部分。 这里的创新可以通过阈值处理，图案识别和/或检测枪口光学闪光灯来确保低的误报率。 在一些实施例中，具有训练有素的人员的检查中心可以在向当地机构报告之前评估事件。 室内系统可以并入室外枪机定位系统，以更好地保护诸如校园或交通枢纽之类的局部区域。 这里的系统和方法可以涉及与附加资源（例如对讲机，手机和访问控制）相关联的特征和功能，以在拍摄的情况下提供减轻伤害。
