Software Design of the Fruit-Tree Shape-Structure Parameters Detection System Based on DSP

根据果树仿形喷雾的特点及要求，设计开发了基于DSP的果树形态结构参数检测系统．该系统能够实时采集果树图像，并进行快速图像处理和果树部分形态结构参数的计算、介绍了系统的软件设计和图像处理算法，并给出了部分果树形态参数的检测结果．试验结果表明，该系统在果树冠幅和树高检测方面有较高的精度．最大冠幅和树高的检测相对误差分别为-2、5％-0％和-3、0％～1．7％．

According to the characteristics and requirement of profile modeling spray, a detection system of shape-structure parameters of fruit-tree was put forward based on the digital signal processing （DSP）. It can gather the real-time video image, process the image quickly and calculate parts of the fruit-tree shape-structure parameters quickly. The software structure and arithmetic of image were introduced in this paper. A image process arithmetic and shape-structure parameters detection example were also given. The experiment results showed that the system could detect the crown and height of fruit-trees with high accuracy. The relative error of crown and height of fruit-tree was within -2.5% - 0% and -3.0% - 1.7% respectively.
