Some new important progresses of the measuring system for fiber position of LAMOST (Large Area Multi-Object Fiber Spectroscope Telescope) are introduced in this paper. This improved model is based on the principle of calculating the photometric gravity's center of the fiber's CCD digital image, which was discussed in the previews paper [3]. More effective image manipulation and data processing methods have been used to improve the measuring precision. How to make a standard target as big as the size of the whole focal plane of LAMOST for calibration between the CCD camera and the focal plane of LAMOST in measurement was an unsolvable problem in the primary measure model, and it has been resolved in the proved design and will be shown next in this article.
