摘　　要：车载红外成像系统利用光电转化、图像识别的原理来形成可视化的图像,增加夜间驾驶的安全性。车载主动式红外成像系统采用半导体红外激光器作为光线发射器,利用凸透镜与凹透镜把光线发散后投射到车前更大的范围,使用黑白CCD摄像机实时采集图像,用FGPA模块处理图像信号,并通过单片机传输给车载LED显示屏。文章提出的改进后的主动式红外成像系统具有激光照射范围大、成像质量高、实时性强等优点。The vehicle infrared imaging system uses the principle of photoelectric transformation and image recognition to form a visual image to increase the safety of driving at night. The vehicle-mounted active infrared imaging system us. es semiconductor infrared laser as light emitter, uses convex lens and concave lens to project light into a wider range in front of the vehicle, and uses black-and-white CCD camera to capture images in real time. The image signal is pro. cessed by FGPA module and transmitted to the vehicle LED display screen by single chip microcomputer. The im. proved active infrared imaging system suggested in this paper has the advantages of large laser irradiation range, high imaging quality and real-time performance.
