The invention discloses a two-dimensional pointing servo control method and a two-dimensional pointing servo control system which are based on image feedback and optical vector theories. According to the two-dimensional pointing servo control method and the two-dimensional pointing servo control system, a measuring camera is additionally arranged in a main optical path, a fast image processing result of imaging is regarded as a feed source, an image servo closed loop is established, a fast scanning swing mirror undergoes active control through image feedback, the adjustment of pointing of a main optical axis of the camera is completed, the imaging target searching and gaze tracking functions are realized, the imaging efficiency of a remote sensing camera is improved, a servo control law is designed through combining an optical vector reflection theory, and the nonlinear relationship between motor rotation angle and optical axis pointing is eliminated, thereby improving the specificity of control, and being co
