摘　　要：汽车主动安全技术用以保证驾驶员及乘客能提前预知危险，并作出相应防范措施。利用红外光源的数字成像技术．结合基于DSP的图像处理，目标检测和追踪算法，实现对前方车辆位置、方向、相对速度等参数指标的实时获取，经处理后将参数输入专家决策系统，最终产生对汽车乘员的视觉及听觉预警报告，指导乘员作出应对措施。由于红外成像技术的广泛适应性．该系统可以应用于各种复杂的昼夜气候状况。Active safety technology to ensure the driver and the passengers to anticipate danger and take appropriate precautionary measures. Digital imaging using infrared light technology, combined with DSP-based image processing, target detection and tracking algorithm, realizing the fi：ont vehicle location, direction and relative speed indicator parameters such as real-time access, and further parameters into expert collision avoidance system and eventually generate of the vehicle occupants with visual and auditory warning, guidance to the crew response. As the wide adaptability of infrared imaging technology, the system can be applied to complex weather conditions day and night.
