  • Patent number: 12283177
    Abstract: The present disclosure relates to systems and methods for monitoring control. The systems may obtain one or more monitoring images associated with a monitoring region captured by a monitoring device. The systems may determine whether a target event occurs in the monitoring region based on the one or more monitoring images. In response to determining that the target event occurs in the monitoring region, the systems may obtain a target time period associated with operations of a warning light associated with the monitoring device based on at least one parameter of the monitoring device. The systems may control the operations of the warning light based on the target time period.
    Type: Grant

  • Patent number: 12063434
    Abstract: The present disclosure relates to imaging systems and methods. An imaging method may include determining a first remaining power based on a maximum power of a camera and a working power of the camera; determining whether an operation condition of a first load is satisfied based on the first remaining power; and in response to a determination that the operation condition of the first load is satisfied, enabling the first load.

  • Publication number: 20240048855
    Abstract: The present disclosure relates to systems and methods for video surveillance. The systems may obtain an initial time period corresponding to at least part of a time period during which at least one target image frame is captured by the monitoring equipment based on at least one parameter of a monitoring equipment. The systems may obtain a warning scheme associated with the initial time period. The warning scheme may include controlling an operation of a light associated with the monitoring equipment within at least one candidate time period in the initial time period and processing the at least one target image frame.

  • Patent number: 11431914
    Abstract: The present disclosure relates to a method for determine exposure parameters of each camera in a multi-view camera. The method may initiate an iteration process including iteration(s). Each current iteration may include: determining a reference exposure brightness; determining whether a first difference between the reference exposure brightness and a predetermined exposure brightness is within a first difference-range; if the first difference is not within the first difference-range, updating a first exposure brightness of each camera by adjusting first exposure parameters of the camera, and re-initiating a current iteration; if the first difference is within the first difference-range, designating the first exposure parameters of each camera as the current exposure parameters of the camera.
