  • Publication number: 20230010105
    Abstract: A method and system for capturing, by a camera a sequence of frames at respective locations within a portion of an environment; capturing, by an inertial measurement unit, a sequence of inertial odometry data corresponding to the sequence of frames at the respective locations; storing in a queue a data record includes information extracted from processing the respective frame and information from the inertial measurement unit; in accordance with a determination that the sequence of inertial odometry data satisfies a first criterion: calculating a first relative pose between the first frame and the second frame; and in accordance with a determination that a difference between the first relative pose and the information extracted from processing the respective frame satisfy a first threshold: generating an initial map of the portion of the environment based on the first data record and the second data record.

  • Patent number: 11417331
    Abstract: The present disclosure provides a method for controlling a terminal, including the following operations: obtaining recognition results corresponding to control signals after receiving the control signals, and determining whether control instructions corresponding to the recognition results conflict, each control signal comprising at least one of a voice signal or a gesture signal; determining a credibility of each control instruction in response to a determination that there exists conflict among control instructions; and sending the control instruction with highest credibility to a control terminal. The present disclosure further provides a device for controlling a terminal and a computer readable storage medium. When control instructions are received and there exists conflict among control instructions, the control instruction with the highest credibility is sent to the control terminal after the credibility of each control instructions is determined, thereby avoiding settings from conflict.
