摘　　要：为满足国防、科研和工业中高速成像的应用要求,设计了一种基于CMOS传感器LUX13HS的高速相机。利用现场可编程门阵列(FPGA)作为相机主控元件,驱动CMOS图像传感器并接收恢复图像数据,获取平均灰度值和直方图信息并在DDR4中进行图像缓存,实现图像预处理和自适应调光,并通过CameraLink接口实时传输。系统测试结果表明:相机在分辨率为1280×720时,成像帧频为1666 fps,实时传输帧频为555 fps,能长时间稳定工作。自适应调光功能和图像预处理增强了高帧频成像的视觉效果,使相机能适应多种应用场景。To meet the application demands of high-speed imaging in national defense,research and industry,further enhance the performance of high-speed camera,a high-speed camera acquisition system with CMOS sensor LUX13HS was developed.It is based on the controlling of FPGA,which drives the operation of CMOS sensor,receives and recovers pixels.The camera could process images and exposure automatically by extracting average gray value and histogram from pixels,after putting into DDR4.Eventually,the images were output in real time with CameraLink interface.The camera can work stably with imaging frame frequency up to 1666 fps and real-time transmission frame rates up to 555 fps,when output 1280×720 pictures.The functions of automatic exposure and image processing embedded in FPGA have big effects on improving the quality of images,which made the camera work in different environment properly.
