Area is the most important piece of information in rail head surface defect detection. However, under the high speed condition, e.g. over 300 km/h, it is hard to obtain the area information because of the partial loss of length and width information. In order to solve this problem, a simple and fast algorithm is proposed. This algorithm adopts the line-scan calibration, and calculates the defect areas which the line-scan camera can get and cannot get respectively. In the traditional algorithm, the area is calculated by counting the number of pixels. Comparing with the traditional method, the experiment shows that our algorithm has the same complexity, but better accuracy in area calculation.
