摘要
为了提高车载视频导航控制子系统的准确度,本文介绍一种基于STM32的视觉导航系统。该系统使用USB摄像头采集周围环境信息,视频通过编码后由无线路由传送到上位机,在上位机的MATLAB中利用现有的灰度和二值化的方法对图像进行处理,以及在Keil软件平台上进行编程,小车采用PID控制算法控制电机的速度,以此用来改变小车移动的方向。通过实验验证,该系统确实能够在一定的区域内实现导航,具有一定的可扩展性。
In order to improve the accuracy of the navigation system, this paper introduces the visual navigation system based on STM32 . The system uses a USB camera to capture the information of surrounding environment, the video encoded before transmitted to the host computer by the wireless router, using exist image processing algorithms for image processing in MATLAB as well as programming in Keil software platform PC＇s , car used PID control algorithm to control the motor speed in order to change the direction of movement . Experiments show that the system can indeed achieve navigate in a certain area, having certain expansibility.
