Abstract
We have developed a system that can measure the distribution of optical distortion over the entire surface of an automotive windshield glass as observed from the driver's eye point with high accuracy by using “distortion angle” as a parameter. This paper introduces the system together with examples of measurement result.
To measure the position of gratings accurately, we adopt the specially designed video cameras and the method for detecting bright line position based on pixel. To reduce the time required for measurement, the filtering process for measured data has been optimized and the data retrieval process has been contrived.
