Paper Abstract

A laser beam based calibration method is proposed in the paper. The laser beam we used can keep the cylinder shape in the real world space. The cylinder shaped laser beam will form an elliptical area in the plane in which the defect we want to measure also located. This elliptical laser area will form an ellipse in the image. Our purpose is to achieve calibration only depending on the elliptical parameters of the ellipse in the image. We created the relationship model between the elliptical parameters of the ellipse in the image and the calibration parameters of the video appliance, and we find a quick and easy way to solve the relationship model. Using this calibration method we can achieve contactless video measurement during the equipment checking in the nuclear power station.
