The present invention provides a method for solving an optical projection mechanism of a camera. The camera comprises a lens, an image formed by the lens has the properties of axial symmetry and nonlinear distortion, and the camera is adapted to form an image in a field-of-view space on an image plane. The method comprises: first, confirming the optical axis and the projection center of the camera in a coordinate space orientation that can be described by an instrument system; next, providing a three-dimensional view target, the three-dimensional view target comprising a front view surface and at least one side view surface, wherein the front view surface and the side view surface each have a first pattern; then, forming the first pattern on the front view surface and on the side view surface on the image plane to form a second pattern; then, aligning the projection center of the camera with a center point of the front view surface of the three-dimensional view target, and causing the optical axis to be perpe
