The present disclosure relates to an augmented reality (AR) image projection system capable of simultaneously capturing a real image and projecting an AR image, and capable of applying same to a subject requiring precise work or in an environment having spatial restrictions. The present disclosure includes a real image capture device for capturing a real image illuminated by invisible rays without interference with visible rays, and an AR image projection device for projecting an AR image, wherein the real image capture device captures a real image and the AR image projection device projects an AR image through the same optical axis. Further, the present disclosure includes a real image capture device, an AR image projection device, as well as additional imaging devices such as a fluorescent camera configured integrally along the same optical axis, and configured to avoid wavelength interference between a light source and an excitation light and the like.
