Target personnel management method and device

The invention provides a target personnel management method and device, and the method comprises the steps: obtaining a plurality of video images collected by a camera device, calibrating all objects in the video images, and determining the same object in the plurality of video images through employing a target tracking algorithm. And judging whether each object is a target person based on pre-stored target person information, when the object is determined to be the target person, detecting whether the distance between the object and other objects is within a safety threshold based on the position information of the target person, and if the distance is not within the safety threshold, sending danger prompt information. According to the scheme, the target person is determined based on image recognition, whether danger possibility exists or not is judged based on the mode of detecting whether the distance is within the safety threshold value or not, then the purpose of effectively monitoring and managing the t
