【摘要】：雜交稻機(jī)械化秧盤精密播種育秧過程中需要人工實(shí)時監(jiān)測,以保證秧盤播種性能,為解決傳統(tǒng)人工長時間戶外、低效的監(jiān)測方式,設(shè)計(jì)了基于嵌入式機(jī)器視覺的水稻秧盤育秧圖像無線傳輸系統(tǒng)。系統(tǒng)由嵌入式開發(fā)平臺、無線Wi Fi網(wǎng)關(guān)、高清網(wǎng)絡(luò)攝像頭、紅外傳感模塊、遠(yuǎn)程服務(wù)器等組成。嵌入式開發(fā)平臺采用Tiny4412開發(fā)板,并在其上移植Linux系統(tǒng)、攝像頭驅(qū)動、GPIO口驅(qū)動;采用Qt開發(fā)工具,完成圖像采集、實(shí)時顯示,并設(shè)計(jì)出友好的人機(jī)交互界面;利用Jpeglib靜態(tài)庫對圖像進(jìn)行數(shù)據(jù)壓縮;利用無線Wi Fi局域網(wǎng)、嵌入式系統(tǒng)和遠(yuǎn)程服務(wù)器按照規(guī)定的協(xié)議通過Socket通信進(jìn)行數(shù)據(jù)傳輸。遠(yuǎn)程服務(wù)器基于Netty框架對采集到的圖像數(shù)據(jù)進(jìn)行校驗(yàn)、實(shí)時顯示和保存。試驗(yàn)結(jié)果表明,不同分辨率圖像的無線傳輸速率均滿足育秧流水線實(shí)時作業(yè)要求,JPEG格式的圖像經(jīng)過數(shù)據(jù)壓縮,其傳輸速率大大提高;嵌入式采集終端能夠穩(wěn)定采集播種秧盤圖像,并成功地上傳到服務(wù)器,網(wǎng)絡(luò)平均丟包率為0.23%,誤碼率為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.
