The embodiment of the invention relates to a projection correction method and device for a projector equipped on a mobile robot. The method comprises the steps of: using a camera equipped on the mobile robot to perform the image shooting and obtaining a shot image when the projector is detected to start shooting, wherein the shot image comprises a projection frame and a projection curtain, and the projector projects the projection frame to the projection curtain; obtaining a relative position relation of the projection image relative to the projection curtain; adjusting the positioning of the mobile robot according to the relative position relation, and enabling the projection frame to be projected suitably to the projection curtain. According to the embodiment of the invention, the projection of the projector equipped on the mobile robot is enabled to be corrected automatically, so that the user experience of the projector equipped on the mobile robot is improved.
Description
Technical field [0001] The embodiments of the present invention relate to the technical field of specific applications of mobile robots, and more specifically, to the projection correction of a projector equipped with mobile robots. Background technique [0002] With the rapid development and maturity of mobile robot technology, the market has increasingly strong demand for various services and applications based on mobile robots. Since the projector is widely used in office and home environments, it has also become an important configuration for mobile robots (usually configured on the front of the robot). The projector effect depends on the relative position and direction of the projector and the screen. Due to the inevitable position and direction errors in indoor navigation technology, the robot-based projector effect will have the disadvantages of screen tilt, small or large screen size, etc. It affects the normal use of the user, and manually adjusts the position and direc...
