Patent number: 11023727Abstract: A target monitoring method, a camera, a controller, and a target monitoring system, where the system includes a first camera and a second camera. An overlapping area exists between fields of view of the first camera and the second camera. The method includes obtaining, location information of a to-be-tracked target in a first monitoring picture when the first camera is used as a current primary monitoring camera, determining, based on the location information of the target in the first monitoring picture, whether a location of the target in the first monitoring picture is in the overlapping area, where the overlapping area is an overlapping range between the fields of view of the first camera and the second camera, and switching, the current primary monitoring camera to the second camera when the location of the target in the first monitoring picture is in the overlapping area.Type: GrantFiled: July 13, 2017Date of Patent: June 1, 2021Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Qiang Ding, Liyao Zhang, Hongrui Jiang

Patent number: 10948994Abstract: When a location of a wearable system changes, the wearable system can ensure that a gesture working region always remains in a field of view of the wearable system. Therefore, the wearable system can still collect and recognize a gesture image and implement gesture control. The solution provided in this application is as follows: The wearable system creates a gesture working region and a region of interest, where the region of interest is within a shooting area of a first camera, and the first camera is included in a wearable device; obtains a location parameter of the wearable system; adjusts the region of interest according to the location parameter, so that the region of interest covers the gesture working region; collects a gesture image within the gesture working region; recognizes the gesture image to obtain a gesture instruction; and performs a corresponding operation according to the gesture instruction.Type: GrantFiled: February 29, 2016Date of Patent: March 16, 2021Assignee: Huawei Technologies Co., Ltd.Inventors: Liyao Zhang, Qiang Ding, Hongrui Jiang

Patent number: 10640038Abstract: This application relates to the field of intelligent hardware, and in particular, to an intelligent scenario in which a mobile terminal and a car are combined. After detecting, by using an acceleration sensor and a gyroscope of the mobile terminal, that a car engine stops, the mobile terminal receives, from a sensor installed near a roof lamp of the car, a signal indicating that the roof lamp is on, and determines that a door of the car is opened. In this case, the mobile terminal sends a reminder to a user.Type: GrantFiled: May 11, 2016Date of Patent: May 5, 2020Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Hongrui Jiang, Qiang Ding, Zheng Lin, Liyao Zhang
