The target-oriented spraying is an effective way to minimize chemical input in agricultural production and it is important to actualizing sustainable agriculture. This article focused on the design and optimization of the target spray platform. The spray platform consists of three parts: the vision system, the spray system, and the moving platform. All components were effectively connected and preliminarily evaluated especially regarding the response time and target spray accuracy. A simulation system was built considering the real crop geometric shape and nozzle spray pattern using the Monte Carlo method. The spray simulator was used to optimize the spray height objective function of spray deposition rate and coefficient of variance for the spray deposition. The spray process can be easily visualized and compared for different spray parameters. The indoor experiment setup was built to test and optimize the parameters of the overall system, which is flexible to verify the system. Afterward, the outdoor tractor-based equipment was designed to test the system for the field environment. The experimental result showed that 80% of the crop had a spray deviation from 0 mm to 28 mm and the proposed spraying system can reduce 46.8% usage of the chemical compared to the uniform spray method.

以目标为导向的喷洒是减少农业生产中化学药品投入的有效方法，对于实现可持续农业非常重要。本文重点介绍目标喷雾平台的设计和优化。喷涂平台包括三个部分：视觉系统，喷涂系统和移动平台。所有组件均已有效连接并进行了初步评估，尤其是在响应时间和目标喷涂精度方面。建立了一个模拟系统，使用蒙特卡洛方法考虑了真实的农作物几何形状和喷嘴喷雾模式。喷雾模拟器用于优化喷雾沉积速率的喷雾高度目标函数和喷雾沉积的变异系数。喷涂过程可以很容易地看到并比较不同的喷涂参数。建立室内实验装置是为了测试和优化整个系统的参数，从而可以灵活地验证系统。之后，设计了基于室外拖拉机的设备，以针对野外环境对系统进行测试。实验结果表明，80％的农作物的喷雾偏差为0毫米至28毫米，与均匀喷雾法相比，所建议的喷雾系统可减少46.8％的化学药剂使用量。
