The invention discloses a key person prevention and control early warning method. The method comprises the following steps: step 1, loading information of an arranged prevention and control point P; step 2, presetting a normal trajectory array A of a certain key person; step 3, if the key person image is identified at the prevention and control point Px, uploading the key person image and information of the prevention and control point Px through the terminal, processing same, and sending an early warning message for abnormal conditions. The method can reduce a large amount of human input, accurately judge whether the personnel trajectory is abnormal or not, and improve the early warning accuracy. 本发明公开了一种重点人员防控预警的方法，步骤1，加载已布置的防控点P的信息，步骤2，预设某个重点人员正常轨迹线数组A，步骤3，若在防控点Px识别到该重点人员图像，则通过终端上传该重点人员图像及发生防控点Px的信息，并进行处理，对异常情况发送预警消息。该方法可以减少了大量的人力投入，精准判断人员轨迹是否异常，提高预警准确性。
