Device and method for light filling of image acquisition device

Abstract

The invention discloses a device and a method for light filling of an image acquisition device. The device comprises a first image acquisition device, more than one second image acquisition device and a light filling device, wherein each of the first image acquisition device and more than one second image acquisition device comprises a signal extraction unit capable of extracting a synchronizing signal of a power grid from an AC electrical signal of the power grid; the first image acquisition device is connected to the light filling device, the first image acquisition device controls work of the light filling device, and the light filling device provides light filling for the first image acquisition device and all second image acquisition devices. According to the device and the method, the single light filling device can carry out light filling on a plurality of image acquisition devices, so that the resource waste is reduced and the solution cost is reduced; a problem of asynchronous exposure of the image acquisition devices connected to an AC network is effectively solved, synchronization of the image acquisition devices and a light filling light is guaranteed, and one light filling device can carry out light filling on the image acquisition devices.

Description

technical field [0001] The invention relates to the technical field of image acquisition, and in particular to an image acquisition device light supplement device and method. Background technique [0002] Intelligent traffic management systems often need to use multiple image acquisition devices, and each image acquisition device is equipped with a supplementary light device, which will cause waste of equipment resources and power resources. Moreover, the power grid connected to the image acquisition device and the supplementary light device uses alternating current, and the alternating current has peaks and peaks and valleys, so the brightness of the supplementary light device connected to the AC power grid will alternate between bright and dark. When a supplementary light device supplies light to multiple image acquisition devices, due to the asynchronous exposure of multiple image acquisition devices, the alternate frequency of bright and dark images of multiple image acq...
