Abstract

The invention relates to a three-dimensional mapping camera for measuring an optical axis point angle in real time. The three-dimensional mapping camera comprises a lens cone and a planar reflecting mirror, wherein the planar reflecting mirror is arranged at one end of an inner wall of the lens cone, the planar reflecting mirror can be used for changing a working angle of the planar reflection mirror by a reflecting mirror rotation mechanism, a laser distance measurement device group is arranged on an inner wall of an end part of the lens cone installed with the planar reflecting mirror, an optical lens is arranged in the lens cone, an imaging detector is arranged on the inner wall of the end part of the lens cone of the optical lens, the optical lens is arranged between the planar reflecting mirror and the imaging detector, and a satellite sensor is arranged on an outer wall of the end part of the lens cone installed with the optical lens. The three-dimensional mapping camera has thecharacteristics flexible mapping with high positioning accuracy and variable base-height ratio can be achieved by employing a light single-lens mapping camera, and the three-dimensional mapping camerais particularly applicable to light and small three-dimensional mapping satellite with high positioning accuracy.
