Abstract: Using traditional measurement method for si lk sectional area,it waste time,strenuosity,and low precision disfigurement. The meas urement method for silk sectional area was advanced based on the technology of c omputer vision. It emploied the system of computer vision to obtain the silk sec tion image,advanced segmentation using the way of fuzzy entropy. The count resul t can be got in according to seed fillng algorithm and the silk single sectio nal-area effectively. The experiment result indicated that the method removed s ubjective error of traditional measurement method,and enhances metrical precisi on. The way adapts the need of roboticized measure for textiles.
