使用不同厂商生产且接口类型不同的高速相机组建一个统一控制的图像采集系统,会大大增加开发的难度。介绍一个由USB3接口CCD相机和GigE接口CCD相机组成的图像采集系统的硬件结构和软件开发方案。硬件方面,相机在外同步触发信号的作用下,由一台图像工作站同时采集两台相机的图像。软件方面,使用不同相机的开发包进行二次开发,系统运行后弹出两台相机的控制与采集界面,采用人机交互方式进行相机配置。两台相机可以独立工作,亦可同步采集。图像采集系统实验表明,系统工作正常,但在工作站完成两台相机单帧图像采集的时间差均值约15 ms。

Using a high-speed camera produced by different manufacturers and interface types to form a unified control image acquisition system will greatly increase the difficulty of development. This paper introduces the hardware structure and software development scheme of an image acquisition system consisting of USB3.0 interface CCD camera and GigE interface CCD camera. On the hardware side, the camera captures two cameras simultaneously for imagery by an external image triggering signal. In terms of software, the development kits of different cameras
are used for secondary development. After the system is running, the control and acquisition interfaces of the two cameras are popped up, and the camera configuration is performed by human-computer interaction. Both cameras can work independently or simultaneously. The image
acquisition system experiments show that the system works normally, but the time difference between the two cameras' single-frame image acquisition at the workstation is about 15 milliseconds.
