In this paper, for the transference phenomenon of high polymers, a method of measurement system based on sodium light and feisuo interference with digital image processing technology was proposed. At first, the system measurement scheme and method were explained and there were some experiments with micro moleculesIn the experiment, the high polymer is the mixture of acetone and organic glass by a certain ratio, the micro molecules are Acetone and ethanol; at last, the interference strips were collected at interval time by using the image control collection procedure and processed. After thinning the fringes, we calculated the fringe spacing distance by K-L transform, by measuring the fringe spacing change in the polymer transference of acetone and ethanol we draw the change rule of the Polymer material refractive index :in 10 mins, the fringe spacing became to 40 percent , the refractive index became 2.5 times and keep invariant for Polymer material; in 50 mins, the fringe spacing became to 56 percent ,the refractive index became 1.7 times and kept invariant for ethanol. That’s all, at the time of balance, it will not infect the capability of the Polymer material any longer.

The author has designed a visual workbench to realize that the rim can rotate with the workbench. Meanwhile, the linear CCD camera records the rim’s circumference. The paper has explored the measurement method of getting the rim valve hole position using machine vision. The system can calculate the position of rim-hole and control the servo motor by image processing, characteristic recognizing and measuring to locate the position of wheel-hole automatically. And the paper has verified the accuracy of the method by experiments.

Most of maternal mortality is directly caused by obstetric hemorrhage and almost three-quarters of it take place in postpartum period. The risk of maternal death due to hemorrhage can be reduced with prompt and proper care that in turn relates to the blood loss measurement method used. Unfortunately, the most commonly practiced method is not yet accurate enough. This research proposes a postpartum blood loss measurement method using digital image processing. Initially, characterization is carried out to find out blood absorbance against digital image area and blood volume in the underpad. Results of this characterization then serve as the basis for blood loss measurement using digital image processing. This measurement basis is validated by measuring blood volume lost during delivery care. Results show that the area and volume of blood absorbed in the underpad has significant linear relation (R = 0.9734). Digital image processing can be used to measure postpartum blood loss with a high accuracy up to 83.7%. The use of this method is therefore an accurate and objective alternative to the other available method. Nonetheless, the use of this new method must also adhere to standard guidelines in delivery care as to ensure the utmost outcomes.
