多相机同步曝光及GPS时间校正的处理与实现

Multi-camera synchronization exposure and GPS time correction processing

在相机同步曝光控制模块的运行过程中,相机图像的连续性和时间记录的准确性决定着同步曝光控制模块的优劣。为了实现稳定、可靠的控制,系统设计以单片机为核心的控制系统,相机同步曝光控制模块主要是通过单片机控制多台相机的同步曝光,并对相机的反馈信号进行处理,产生相机补拍信号,自动控制相机进行补拍动作,弥补正常同步曝光时产生的漏拍、延迟拍摄动作。系统通过GPS进行时间校正,增加了同步曝光控制模块的可靠性。

During the operation of the camera synchronous exposure control module, the continuity of the camera image and the accuracy of the time record determine the synchronous exposure control module of the pros and cons. In order to achieve a stable and reliable control, the design is based on single chip as the core control system. The camera is synchronized by the microcontroller to control the synchronization of multiple cameras exposure, to deal with the feedback signal of the camera, to produce the re-photographed signal in automatic control and to make up for the leakage in the normal sync exposure delayed shooting. The system is tested through the GPS time correction and the reliability of synchronous exposure control module is guaranteed.
