The present invention falls within the technical field of robots, and particularly relates to a robot monitoring system. The robot monitoring system based on human body information comprises an image collection unit for collecting an image; a human body detection unit for determining whether human body information matching a training sample exists in the image; a target acquisition unit for acquiring position information and size information about the human body information in the image; a target tracking unit for acquiring a current motion region according to a frame difference between the image and a predetermined image frame and acquiring a moving target from the motion region; and an adjustment unit for adjusting the orientation of the image collection unit such that the moving target is located in the centre of the image. By means of the technical solution, human body information is detected to track a moving target, so that a monitoring centre always tracks the position of a human body, thereby effectively realizing human body positioning and tracking, so as to monitor content information of interest.
