The invention provides a projection method, device and system and a readable storage medium. The method is applied to a projection system, the projection system comprises a shooting device, an identification device and a projection device, the projection method comprises the steps of acquiring a three-dimensional local image for an affected part wherein the three-dimensional local image comprisesa virtual path; when the simulation two-dimensional image obtained based on the three-dimensional local image projection is matched with the two-dimensional projection image obtained based on the affected part, acquiring three-dimensional posture information of the three-dimensional local image to serve as perspective position information of the affected part based on a perspective coordinate system, and forming the perspective coordinate system based on a shooting device; obtaining a first conversion relationship between the identification coordinate system based on the identification deviceand the perspective coordi
