Summary:The projectors, which projects images to the center of the screen, are commonly used for official meeting, family filming, etc. The projectors can perform autofocus and auto keystone correction of images. However, the position of the projected image needs the manual alignment, which makes it inconvenient to get the right position quickly. In order to solve this problem, we design a robot with visual perception and closed-loop control, which can find the right area for the projection, and automatically correct the position of the projected image as at the center of the area. The experimental results show the feasibility and effectiveness of the robot.
