Design of a Machine Vision Line-travel Obstacle Avoidance Trolley

提出了一种基于STM32f103rct6嵌入式微处理器的图像识别智能小车模型,可应用于勘测领域。通过摄像头进行信息采集和图像识别,配合小车液晶监控系统,能够实时接收搭载的OV7670摄像头传输的二值化处理后的视频和图像,对前方路径情况进行监控。同时,为避免小车行驶过程中发生碰撞,利用超声波技术测距避障。经过实际的调试和运行,结果表明小车系统能较好地执行完成视觉巡线和自动避障任务。

This design proposes an image recognition intelligent car model based on STM32f103rct6 embedded microprocessor,which can be applied to the field of surveying.Through the camera for information collection and image recognition,combined with the car's LCD monitoring system,it can receive the binary processing video and image transmitted by the equipped OV7670 camera in real time and monitor the forward path.At the same time,in order to avoid collisions during the driving of the car,ultrasonic technology is used for distance measurement and obstacle avoidance.After actual commissioning and operation,the results show that the trolley system can better perform the tasks of visual line patrol and automatic obstacle avoidance.
