PROBLEM TO BE SOLVED: To provide a measuring method that enables the tilt shapes of tips of wiper blades to be quantitatively and stably grasped.SOLUTION: A plurality of laser displacement sensors are so arranged in the interior of a wheeled vehicle as to oppose a glass surface, and the distance to the tip of each wiper blade working on the glass surface is continuously measured through the glass. On the basis of data measured by the laser displacement sensors, three-dimensional shape data of the tip of each wiper blade is generated, two-dimensional shape data of the tip of each wiper blade is extracted from this three-dimensional shape data, and the tilt angle of the tip of each wiper blade is calculated. |
