The projector calibration method includes the following steps. A first preset image is projected by a first projector to a dome screen, and a first deformed image is obtained by capturing an image of the dome screen using a first camera. A spatial relationship between the first projector, the first camera, and the dome screen is calculated according to the first preset image and the first deformed image. A first prewarp image is generated according to a target image, a spatial relationship between the first projector and the dome screen, and a spatial relationship between the dome screen and the viewing point. Projection is performed by the first projector according to the first prewarp image. In addition, a projection system using the method is also provided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projector calibration method and projection system using the same","description":"The invention provides a projector calibration method for forming a spherical target image at a viewing point.
