The first image includes a first object, a second object, a first set of reference marks, a second set of reference marks, and a first boundary mark. The touch screen establishes relationships of relative positions among the first image sensor, the first object, the second object, and the reference marks according to positions of the first object, the second object, and the reference marks in the first image. And the touch screen calculates a relative position between the first image sensor and the panel according to the relationships of relative positions among the first image sensor, the first object, the second object, and the reference marks and relative positions among the first object, the second object, and the panel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Object detection calibration system of an optical touch screen and method thereof","description":"A first image sensor captures a first image of a panel of a touch screen.
