The projection apparatus is configured to project an image onto a screen. The first ultrasonic sensor and the second ultrasonic sensor are disposed on the projector body. The first ultrasonic sensor and the second ultrasonic sensor are respectively configured to measure a distance between the projector body and the screen. The projector body corrects the image in a horizontal direction through the first ultrasonic sensor and the second ultrasonic according to the measured distances. The first ultrasonic sensor and the second ultrasonic sensor are disposed on a first reference line corresponding to the first direction. The projection apparatus of the invention may provide good image quality."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projection apparatus","description":"A projection apparatus is provided, which includes a projector body, a first ultrasonic sensor and a second ultrasonic sensor.
