Disaster monitoring method, device and system and computer storage medium

The invention provides a disaster monitoring method, device and system and a computer storage medium. The method comprises the following steps: acquiring an image of an urban rail vehicle operation area; the image of the urban rail vehicle operation area is input into a difference image recognition model, the similarity is determined, and the similarity is used for representing the similarity between the image of the urban rail vehicle operation area and a preset disaster image; and determining the disaster condition of the urban rail vehicle operation area based on the similarity. According to the method, manpower consumption can be effectively reduced, the disaster situation of the urban rail vehicle operation area can be determined more accurately, and the effect of improving disaster monitoring efficiency and accuracy is achieved. 本申请提供一种灾害监测方法、装置、系统和计算机存储介质，所述方法包括：获取城轨车辆运行区域的图像；将城轨车辆运行区域的图像输入差别图像识别模型，确定相似度，其中相似度用于表征城轨车辆运行区域的图像与预设灾害图像之间的相似度；基于相似度确定城轨车辆运行区域的受灾情况。该方法可以有效减少人力消耗，更准确的确定城轨车辆运行区域的受灾情况，达到了提高灾害监测效
