A profile inspection method which can measure the height distribution of a roadbed from a high-speed vehicle is required for a health monitoring of the roadbed. A light-section method is often used for this purpose. The analysis time is, however, long because this method analyzes a 2-D image to obtain a height distribution along a line. An intensity ratio method was proposed as a profile measurement method. This method can be realized with simple equipments. We are developing a high-speed profile measurement method of a moving object using three linear sensors set in parallel. In this paper, we propose a profile inspection method with three linear sensors by the intensity ratio method.
