The invention discloses a method, a device and equipment for determining geometric parameter information of a spherical object of a bolt, relates to the technical field of constructional engineering,and can efficiently and accurately extract a sphere center coordinate and a sphere radius of the spherical object of the bolt. The method comprises the steps of firstly collecting three-dimensional scanning information of a spherical object of a bolt, and obtaining a bolt spherical point cloud model; carrying out noise point filtering on the bolt sphere point cloud model through a preset RANSAC algorithm; estimating model parameter information corresponding to the filtered bolt sphere point cloud model; and finally, according to the model parameter information, determining the geometric parameter information of the spherical object of the bolt. The method is mainly suitable for determining the geometric parameter information of the spherical object of the bolt. 本发明公开了一种螺栓球状物几何参数信息的确定方法、装置及设备，涉及建筑工程技术领域，可高效、精确地提取螺栓
