An original image is projected as a projection image on an object. A projection-zone image including the projection image is captured from the object. A projection image outline corresponding to the projection image is obtained from the projection-zone image. An operation is performed on the projection image outline to obtain a horizontal inclination and a vertical inclination. The original image is pre-warped according to the horizontal inclination and the vertical inclination to obtain a corrected image, and the corrected image is projected on the object."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for projection correction by capturing projection image","description":"A method for projection correction includes following steps.
