摘要

人体目标识别技术是当前研究的热点，目前一些汽车生产商、大学研究机构都相继开始了人体检测识别技术的研究，并取得了一定的成就。目前常用的人体识别方法有基于运动特性的方法、基于形状信息的方法、基于行人模型的方法等。传统的方法基本上都是基于图像的，往往设备昂贵，计算复杂度高，而热释电红外传感器探测人体发出的红外辐射，在有效范围内可实现运动人体检测。因其具有低成本，低功耗和高灵敏度等特点而得到了广泛应用

关键词：红外热释电传感器、STM32

ABSTRACT

Human target recognition technology is the hotspot of the current research. At present, some automobile manufacturers and university research institutions have started the research of human detection and recognition technology, and have made some achievements. At present, commonly used methods of human body recognition are based on the method of motion characteristics, the method based on shape information, the pedestrian model based method. The traditional method is basically based on the image, often expensive equipment, high computational complexity, and pyroelectric infrared sensor to detect the infrared radiation emitted by the human body, in the effective range can be achieved in the movement of human detection. Because of its low cost, low power consumption and high sensitivity and other characteristics have been widely used

KEY WORDS: Infrared pyroelectric sensor、STM32
