Design of Projector Correction system based on RK3399

In real life, the projector projection picture is not flat, there is a certain deformation. Traditional method is to adjust the position of the projector manually, but it is not convenient in real scenes, and the two projectors are simply corrected by the traditional method, so the projection effect in the overlapping area is not ideal. In recent years, there is also a lot of research on how to do the work of the projector correction, and put forward a lot of solutions, but most of them are very tedious. This paper presents a correction method using embedded device RK3399 combined with OpenCV software, which can manually and automatically correct the projection picture of one or two projectors by software control, and deal with the projection overlap area, which makes the visual effect of projection better and the operation convenient. It can be widely used in the projector system of prisons and command centers.
