Abstract: The present invention relates to a method for processing ophthalmology medical images, and specifically relates to a machine vision-based method for processing eccentric photorefraction images. The present invention employs a Harr-like rectangle feature-based Adaboost strong classifier self-learning method to locate the pupil region, wherein a principle of eccentric photography makes a near-sighted or far-sighted pupil produce uneven brightness, and employs the Wallis dodging algorithm to homogenize the grayscale value of the pupil to the greatest extent, thereby enhancing edge information of the pupil. Then, binarization blob analysis is performed, noise points and interference regions are removed, retaining only the region where the pupil is located, then a precise pupil boundary is obtained by using a grayscale difference method at the binarized edge of the pupil, and finally elliptical fitting is performed on the basis of the method of least squares to output pupil region parameters. The present invention eliminates interference information and accurately obtains pupil region parameters, thereby helping to improve the precision of optometry for infants and people who are not cooperative.

Abstract: The present application provides a downlink reference signal-based time synchronization method and apparatus. A terminal device receives configuration information of multiple downlink reference signal groups sent by an access network device, each of the multiple downlink reference signal groups comprising at least one downlink reference signal, receives, in the same time unit or K adjacent time units, the multiple downlink reference signal groups sent by the access network device, and selects, according to a preset combination rule, or combination indication information sent by the access network device, all or some of the multiple downlink reference signal groups for combination detection to obtain synchronization information. Because multiple downlink reference groups are sent in the same time unit or K adjacent time units, downlink reference signals used for combination detection have a small interval in time domain, ensuring that the multiple downlink reference signal groups used for combination detection are within 10 ms, and the detection result has a high correlation.

Abstract: A predictive thrust control method and system of an arbitrary double vector model for a linear induction motor, which relate to the technical field of linear induction motor control. In view of the shortcomings of traditional models for predicting thrust control, only one voltage vector is applied in each switching cycle, resulting in the problem of relatively high thrust and magnetic flux linkage pulsation. By means of combining double vector modulation algorithms, two voltage vectors are used in one cycle to improve modulation accuracy, so that the pulsation amplitude may be reduced and the running performance of the motor is improved. The addition of the double vector modulation strategy increases the complexity of the algorithms, and the calculation and solution process is too complicated. At the same time, a simplified search process is further provided to replace traditional repeated calculation and comparison methods without the complicated online calculation process, which thereby simplifies the implementation process of the algorithms in the actual system.
