1. A night vision system of a vehicle comprising: a lane recognition module comprising a lane detection image capturing device and a first controller configured to receive lane detection image data from the lane detection image capturing device and output the lane detection image data to a second controller; a far-infrared night vision module comprising a far-infrared image capturing device and the second controller, wherein the second controller is configured to receive the lane detection image data from the first controller, receive a far-infrared image from the far-infrared image capturing device, set the far-infrared image as a reference image with reference coordinates and correct the lane detection image data to match the reference coordinates, and then, combine the corrected lane detection image data from the first controller with the far-infrared image such that lanes from the lane detection image data are matched to the far-infrared image based on the reference coordinates of the far-infrared image, and output the combined image to a display means; and a thermal sensor and a far-infrared lamp installed around a fog light or head light to carry out an imaging operation of the far-infrared image capturing device such that the far-infrared lamp emits far-infrared rays toward a subject area in front of the vehicle and, at the same time, the thermal sensor detects heat of an object in front of the vehicle, wherein the far-infrared image capturing device takes the far-infrared image that is an image of a road in front of the vehicle, and the image is transmitted to the second controller, and at the same that the far-infrared image capturing device takes the image, the lane detection image capturing device takes a lane information image of the road, which is transmitted to the first controller.
