【正文】 raction system which aimed to extract the welding seam from two CCD cameras with wideangle lenses. In order to satisfy the precision requirement, the distortion of the image must be dealt with. Based on this background, we have proposed a distortion measure that can be utilized to calibrate the radial and decentering distortion parameters of the wideangle lens. In future, we will consider the effect of the noise and analyze the robustness of the algorithm. Zoom system technology parameters such as mentioned in section II. By the system indicators and the above optical system aberration about the characteristics of the initial structure of the optimization: (1) change the zoom ratio, so that the new system meets the requirements zoom ratio. Because the original zoom Bibi We design the system required nearinfrared zoom ratio, so the original minimum focal length optical system for new account the minimum focal length optical system, and then used as criteria for narrowing the magnification changer. Because the zoom system as a whole .The greatest impact is the image quality when imaging short focal quality and zoom ratio, in this way to change the zoom ratio, in a Certain extent by the focus in the short time to improve the image q
