【摘要】：杂交稻机械化秧盘精密播种育秧过程中需要人工实时监测,以保证秧盘播种性能,为解决传统人工长时间户外、低效的监测方式,设计了基于嵌入式机器视觉的水稻秧盘育秧图像无线传输系统。系统由嵌入式开发平台、无线Wi Fi网关、高清网络摄像头、红外传感模块、远程服务器等组成。嵌入式开发平台采用Tiny4412开发板,并在其上移植Linux系统、摄像头驱动、GPIO口驱动;采用Qt开发工具,完成图像采集、实时显示,并设计出友好的人机交互界面;利用Jpeglib静态库对图像进行数据压缩;利用无线Wi Fi局域网、嵌入式系统和远程服务器按照规定的协议通过Socket通信进行数据传输。远程服务器基于Netty框架对采集到的图像数据进行校验、实时显示和保存。试验结果表明,不同分辨率图像的无线传输速率均满足育秧流水线实时作业要求,JPEG格式的图像经过数据压缩,其传输速率大大提高;嵌入式采集终端能够稳定采集播种秧盘图像,并成功地上传到服务器,网络平均丢包率为0.23%,误码率为0.23%。
[Abstract]:In order to ensure seeding performance of hybrid rice mechanized seedling tray, artificial real-time monitoring is needed in the process of precision seeding and raising seedling with mechanized rice seedling tray. In order to solve the problem of traditional artificial long time outdoor and low efficiency monitoring method, A wireless image transmission system for rice seedling tray based on embedded machine vision is designed. The system consists of embedded development platform, wireless Wi Fi gateway, high definition webcam, infrared sensor module, remote server and so on. The embedded development platform adopts Tiny4412 development board, and transplant Linux system on it, the camera drives the GPIO port, the QT development tool is used to complete the image acquisition, real-time display, and the friendly man-machine interface is designed. Jpeglib static library is used to compress image data, and wireless WiFi LAN, embedded system and remote server are used to transmit data through Socket communication according to the prescribed protocol. The remote server verifies, displays and saves the collected image data based on Netty framework. The experimental results show that the wireless transmission rate of images with different resolution can meet the requirement of real-time operation of seedling raising pipeline and the data compression of JPEG format can greatly improve the transmission rate. The embedded acquisition terminal can stably collect the images of seeding seedling tray and successfully transmit them to the server. The average packet loss rate of the network is 0.23 and the error code rate is 0.23.
