Touch screen test equipment contact calibration method and device

The invention discloses a touch screen test equipment contact calibration method and device. The method comprises the following steps: acquiring an image containing a touch screen and a contact; the front edge of the test equipment serves as the X axis of a coordinate system, the image is processed, and the deviation angle between the touch screen and the front edge is calculated; according to the deviation angle, the pose of the touch screen is adjusted; after the pose adjustment of the touch screen is completed, the relative positions of the touch screen and the contact are calibrated according to the three-dimensional coordinates of the original point of the touch screen and the three-dimensional coordinates of the contact; accurate positioning of the touch screen and the contact is achieved through the image measurement technology, errors of a traditional mechanical adjustment mode are avoided, the calibration process can be rapidly completed, and the test efficiency and accuracy are improved. 本发明公开一种触摸屏测
