The invention provides a method and a system for detecting a dangerous area of a container crane. The method comprises the following steps: acquiring a picture of a container crane area acquired by a camera, and detecting a container and a human body in the picture; world coordinates of a human body standing point and world coordinates of eight corner points of the container are calculated according to the installation position and the inclination angle of the camera; and judging whether the human body is in a dangerous area according to the world coordinates of the eight corner points of the container and the world coordinates of the human body standing points. By the adoption of the technical scheme, whether the human body is in a dangerous area or not can be accurately judged under the condition that the hoisting height is adjusted.

    本发明提供了一种集装箱吊机危险区域检测方法及系统,所述方法包括:获取摄像头采集到的集装箱吊机区域的图片并在所述图片中检测集装箱和人体;根据摄像头安装位置、倾斜角度分别计算人体站立点的世界坐标和集装箱八个角点的世界坐标;根据集装箱八个角点的世界坐标和人体站立点的世界坐标判断人体是否在危险区域。采用本发明的技术方案,可在吊装高度调整的情况下准确地判断人体是否处于危险区域。
