1. A module for sensing a dynamic contact pressure of a tire, which performs a test suitable for a road situation by changing an installation place or a disposition position, the module comprising:

  • a transparent contact plate which comes in contact with a tire;

    a 3-axis road cell which is installed on a lower face of the contact plate and measures force acting in each direction of x, y, and z axes generated on the tire;

    a camera module which takes an image of a contact face of the tire coming in contact with the contact plate;

    a support plate to which the camera module and the 3-axis load cell are fixed and supported; and

    a computer which includes a program of calculating a dynamic contact pressure, a contact shape, and a deformation amount from signals detected by the camera module and the 3-axis load cell, and an image correction program.
