Patent number: 11573858Abstract: The present disclosure relates to systems and methods for operation retry. The system may determine whether a retry is allowed for a target operation based on a retry strategy included in a retry proxy component. In response to determining that the retry is allowed for the target operation, the system may execute the target operation. The system may detect whether there is an exception associated with the execution of the target operation. In response to determining that there is the exception associated with the execution of the target operation, the system may determine whether a retry is needed for the target operation based on the retry strategy. In response to determining that the retry is unneeded for the target operation, the system may stop the target operation.Type: GrantFiled: December 2, 2020Date of Patent: February 7, 2023Assignee: BEIJING DIDI INFINITY TECHNOLOGY AND DEVELOPMENT CO., LTD.Inventors: Hongfeng Wang, Yu Wang, Duokun Zhang

Patent number: 9763630Abstract: A stereoscopic imaging system and method is disclosed. In one aspect the system includes an X-ray source that emits a plurality of X-ray fanbeams. The system includes columns of detectors. Each column of detectors is arranged at a preset angle with respect to the X-ray source. The detectors detect a strength of an X-ray fanbeam penetrating an object under inspection. The detectors form transmission images when the object intersects, or moves along a direction intersecting with, the X-ray fanbeams. The system includes a reconstruction apparatus that uses any two of the formed transmission images as a binocular image. The reconstruction apparatus calculates depth information of the object on the transmission images. The reconstruction apparatus superposes and fuses the calculated depth information to obtain 3D information. The reconstruction apparatus performs 3D reconstruction so that the detected object can be presented in a stereoscopic manner from different view angles.Type: GrantFiled: October 27, 2014Date of Patent: September 19, 2017Assignee: Nuctech Company LimitedInventors: Zhiqiang Chen, Zhuowen Tu, Liang Li, Ziran Zhao, Duokun Zhang, Zhi Peng, Jin Cui, Dong Lin
