Patent number: 11176685Abstract: Embodiments of a method and device for controlling image capturing and a system for acquiring an image of a chassis of a vehicle are provided, which relate to image capturing technology and can eliminate deformation of images occurred due to stretch or compression in image capturing. The system includes a speed measuring module, a control module, and a line scan camera. The speed measuring module measures the speed of the vehicle and transmits the measured speed of the vehicle to the control module. The control module determines line frequency for image capturing according to the speed of the vehicle, and controls the line scan camera to perform image capturing on the chassis of the vehicle with the line frequency.Type: GrantFiled: April 26, 2018Date of Patent: November 16, 2021Assignee: HANGZHOU HIKROBOT TECHNOLOGY CO., LTDInventors: Yuanji Chen, Pinjiang He, Wencong Zhang

Patent number: 11055335Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium determining image relevance responsive to a search query. A method includes, for each resource in a plurality of resources, wherein each resource includes one or more images and text that is separate from each of the one or more images: determining, by a data processing apparatus, and from the text of the resource, resource topics described by the text of the resource. For each of the one or more images, processing the image to determine a set of image topics that describe topics to which content depicted in the image belongs. Determining, by the data process apparatus, one or more topic match scores, wherein each topic match score is a measure of relevance one or more of the image topics of the image to one or more of the resource topics of the resource.Type: GrantFiled: July 15, 2016Date of Patent: July 6, 2021Assignee: Google LLCInventors: Wencong Zhang, Jyoti Sood, Kamal Tiwari, Amitabh Saikia, Venkatesh Manickavasagam, Yilin Xiong

Patent number: 10922834Abstract: A method for determining volume of an object includes: obtaining a target depth image containing a target object which is captured by a depth image capturing device (S101); performing segmentation based on depth data in the target depth image to obtain a target image region corresponding to the target object (S102); determining a target circumscribed rectangle that corresponds to the target image region and meets a predetermined condition (S103); determining volume of the target object based on the target circumscribed rectangle and the depth data of the target depth image (S104). Compared to the laser-based determination method in the prior art, this method employs a depth image capturing device without a laser measurement device, and thus the economic cost is lower. Further, compared to the manual scale-based determination method in the prior art, the method employs a software program to automatically determine volume without manual cooperation, and has a higher accuracy and efficiency.Type: GrantFiled: March 30, 2017Date of Patent: February 16, 2021Inventors: Wencong Zhang, Kuang Wu, Yonghua Jia
