Abstract: A detection system of fibrils collection with large field was designed. The transparent fibrils were isotropic irradiated by the ringlike fluorescent lamp, and which were separated by the self-designed electrostatic dividing system. The fibrils image with large field was collected twice by the photographic lens which was driven by a stepping motor in the system. In order to reduce the total calculating amount, the stitching algorithm was proposed to accomplish the fibrils image merger in which the template numbers were increased, the searching region was restricted and the total areas were decreased. The single pixel tracking algorithm was presented to count the number of the fibrils collection, and which could solve the complex problems such as bifurcations, overlap and so on. The test result shows that the measurement accuracy is more than 93.3% and the repeatability average error of the system is less than 1%.

Key words: computer application, large field, electrostatic dividing, image stitching, single pixel tracking
