The invention relates to a point cloud-based reconstruction analysis method and system for an irregular object image, and belongs to the technical field of graph visualization. The method comprises the following steps: importing an image; carrying out image point cloud computing processing; acquiring a central point B of an object in the image under the world coordinate system; an object coordinate system with the original point being the center point B of the object relative to the object is constructed; solving the maximum diameter of the object; calculating camera coordinate points; calculating a camera rotation angle; the obtained camera coordinate point and camera rotation angle are given to the virtual three-dimensional camera, and the camera angle of view is the front view of the output object. According to the method, through a series of calculation such as point cloud analysis of the two-dimensional picture and space relation simulation of the camera and the object, the front image of the needed obje
