The invention provides a human body detection method and device, and the method comprises the steps: obtaining a to-be-detected image; based on the to-be-detected image, determining position information used for representing skeleton key points of a human skeleton structure and position information used for representing contour key points of a human contour structure; and generating a human body detection result based on the position information of the bone key points and the position information of the contour key points. According to the embodiment of the invention, the human body can be expressed with less data volume, the skeleton features and the contour features of the human body are extracted to express the human body, and the representation fineness is improved.
