Problems solved by technology

[0004] However, due to the limited range of invisible light bands, the working band configured by the image acquisition device may be close to the visible light band visible to the human eye, thereby causing interference to people around the image acquisition device

Abstract

The invention provides an exposure control method and device, equipment and a storage medium. The method can comprise the step of controlling a rolling shutter RS device to carry out exposure according to a first preset exposure duration; according to a preset time difference between the initial exposure time of the RS equipment and the initial exposure time of global shutter (GS) equipment, controlling the GS equipment to carry out exposure according to a second preset exposure duration, wherein the sum of the first preset exposure duration and the second preset exposure duration is not greater than the difference between the image frame acquisition period of the RS equipment and the effective processing duration of effective pixel rows of the RS equipment in a single image frame acquisition period; the preset time difference is not less than the effective processing duration and is not greater than a difference value between the single image frame acquisition period and the sum of the first preset exposure duration and the second preset exposure duration.

Description

technical field [0001] The present application relates to computer technology, in particular to an exposure control method, device, equipment and storage medium. Background technique [0002] With the advancement of science and technology, image acquisition technology is widely used. In more and more situations, multiple image acquisition devices will be deployed in the same place for image acquisition. However, during the image acquisition process, these image acquisition devices may cause exposure interference with each other at certain points in time, resulting in failure to acquire images normally. [0003] At present, the method for solving mutual exposure interference between multiple image acquisition devices is usually to configure each image acquisition device to work in different bands, and avoid exposure interference through filtering technology. [0004] However, due to the limited range of the invisible light band, the working band configured by the image acqu...
