Crop Coverage Measurement System Design for Intelligent Fertilizing Machine——Based on Beidou Navigation and Multimedia Image Processing

为了提高施肥机的智能化水平,实现施肥机械的变量施肥控制,提出了一种基于北斗导航和多媒体图像处理的智能施肥机测量系统,并重点对系统作物覆盖率的测量系统进行了设计。本研究采用北斗卫星导航系统(BDS)为采棉机进行位置服务,采用GPRS无线通信技术,避免了通信链路小、覆盖面积小等问题,采用多媒体图像的去噪处理,提高了装置对恶劣天气的自适应能力。最后,在普通的施肥机械上搭载了智能施肥机作物覆盖面积测量系统进行了试验,结果表明:该系统可以成功地返回准确的作物覆盖率,且在雾雨天气也能够保持良好的准确性,从而验证了装置的可靠性,为现代智能的农机设计提供了较有价值的借鉴。

In order to improve the level of intelligent fertilizing machine,realize the variable fertilization machinery control,it put forward a kind of Beidou navigation and multimedia image processing system based on intelligent fertilizing machine measurement system,and focuses on the crop coverage rate measurement system. This research used the Beidou satellite navigation system（ BDS） location service for cotton picker by using GPRS wireless communication technology to avoid the problem of communication link. Small coverage area is small by the use of multimedia image denoising,which can improve the adaptive ability of bad weather device. Finally,it studied the ordinary fertilizer machinery equipped with intelligent fertilizing machine crop cover area measurement system. The experimental results showed that the system can successfully return accurate crop coverage,and maintain a good accuracy in the fog rain weather also,so as to verify the reliability of the device,which can provide more valuable reference for the design of modern intelligent agricultural machinery.
