Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Keystone correction is an essential operation for projector-based applications, especially in mobile scenarios. ,  propose a handheld movable projection method that can freely project keystone-free content on a general flat surface without adding any markings or boundary on it. Such a projection system can give the user greater freedom of display control (such as viewing angle, distance, etc.), without suffering from keystone distortion. To achieve this,  attach a camera to the projector to form a camera-projector pair. A green frame with the same resolution as the projector screen is projected onto the screen. Particle filter is employed to track the green frame and the correction of the display content is then achieved by rectifying the projection region of interest into a rectangular area.  built a prototype system to validate the effectiveness of the method. Experimental results show that our method can continuously project distortion free content in real time with good performance.
