Six-degree-of-freedom rotation calibration mechanism

The invention discloses a six-degree-of-freedom rotation calibration mechanism which comprises a load mounting assembly, a bias flow assembly, a transverse rolling assembly and a pitching assembly. The load installation assembly is installed on the bias flow assembly, the transverse rolling assembly is installed on the bias flow assembly, and the pitching assembly is installed on the transverse rolling assembly. According to the invention, a self-lubricating material is selected to be used as a rotating component, and a stop knob is used as a stop component, so that the mechanism is accurate in rotation, light in weight, small in size, simple in structure and low in price, can be fixed at any position, has the significance of universal use, and can well meet the requirement of measuring the internal error of the aerial photographing system. 本发明公开了一种六自由度转动标定机构，包括载荷安装组件、偏流组件、横滚组件和俯仰组件；所述载荷安装组件安装在偏流组件上，所述横滚组件安装在偏流组件上，所述俯仰组件安装在横滚组件上。本发明通过选择使用自润滑材料作为转动部件，止动旋钮作为止动部件，实现机构转动精确，质量轻，体积小，结构简单，价格低廉，在任意位置都可固定，具有普遍性使用的意义，能
