A system for generating calibration information for an optical imaging touch display device includes a calibration tool and a processor. The calibration tool is disposed within an image capturing range of an image capturing unit, and has a surface with mark patterns. Each adjacent pair of the mark patterns defines a pattern boundary. The calibration tool is disposed such that the pattern boundary forms a predefined positional relationship with a corresponding predefined location on the optical imaging touch display device. The processor receives an image frame corresponding to an image of the surface of the calibration tool, performs edge detection on the image frame to determine a position of each of at least one detected pattern edge, and generates the calibration information with reference to the position thus determined and the corresponding predefined location.
