摘　　要：通过对通用的位移传感器的特点以及问题进行分析与研究,提出并设计了一种利用模拟摄像头采集视频图像信息,进行实时处理的自适应视频识别。系统采用STM32系列ARM微控制器作为主控制器,包括模拟摄像头、视频图像分离、高速AD转换、光线检测及433 MHz无线通信等模块,通过C语言编程实现。在检测物体位移的同时,可以判别物体的移动方向,弥补了现存位移传感器无法检测物体移动方向的空缺,在确保基本检测功能的同时又增加了对环境的自适应,最后通过试验证明了设计的可行性。A kind of adaptive video recognition was designed using analog camera to capture video images by analyzing the characteristics and problems of the general displacement sensor. The system used STM32 series ARM microcontroller as the main controller, including analog camera, video image separation, high-speed AD conversion, light detection and 433 MHz communication module by C language programming. The moving direction of the object also could be detected to overcome the shortcomings that the existing displacement sensor could detect the moving direction, and enhance the adaptability to the environment. The design was proved to be fine in feasibility.
