Digital Image Processing Technology And Its Application In Measurement Of Vehicle Tire Quality

With the rapid development of computer as well as figure signal management technology, computer image processing technology is more and more widely used in various kind of areas as a technology in research of object expression and recognition. As its application in automatic quality of production testing system. Computer vision technology arouses widely attention of people and becomes a new hot spot in research.This thesis will introduce a new method, which can more precisely complete tire footprint pattern and pressure distribution measurement. The principle of the pressure-sensitive mats and measurement system will be presented. The digital image processing methods of the footprint pattern and pressure distribution images, which may be characterized into the tire contact area on the ground under a specific load, ratio of contact area to the total area of the footprint pattern, ratio between the length and width of the footprint pattern, pressure center associated with the tire footprint pattern, etc, will be depicted.
