信号分析处理案例教学应用:雾滴测试卡图像识别与分析

A Teaching Case of Signal Analyzing and Processing:the Image Recognition and Analysis of Droplets Testing Cards

对水稻无人机植保农药喷洒雾滴测试工程应用进行分析与抽取,提炼信号分析与处理的教学案例——雾滴测试卡图像的识别与分析,设计了信号分析处理教学案例的基本功能:雾滴测试卡图像读取、背景去噪、信号降维、雾滴数量解析和雾滴分布均匀性评估等,并给出信号分析处理教学案例图像处理的理论算法与Matlab仿真实现。

An analysis of the application of droplets testing in the pesticide spraying engineering which was used in rice-oriented unmanned-aerial-vehicle （UAV）-assisted plant protection was made and relevant data were extracted to refine a signals-analyzing-and-processing-oriented droplets testing cards. In this process the basic functions teaching case of the image recognition and analysis of of the teaching case was designed as the image reading, background denoising, signal dimensionality reducing, droplet number analyzing and droplets distribution uniformity evaluation of droplets testing cards. Also, the theoretical algorithm and the Matlab simulation implementation of the image processing of the signal-analyzing-and -processing-oriented teaching case were provided.
