摘要
根据仿形喷雾的作业要求,开发设计了一套基于DSP的果树形态参数检测系统,可以对果树图像进行实时采集和处理,并快速计算出果树的部分形态结构参数。主要介绍检测系统的软件设计和果树形态参数的检测计算。经实验验证,系统对果树最大冠幅和高度的检测相对误差分别在-2.51%～0%和-3.0%～1.7%范围内,同时郁密度检测也基本上能够反映出果树的实际稀密程度。
According to the requirement of profile modeling spray, a detection system of shape-structure parameters of fruittree was put forward based on digital signal processor （DSP）. It could gather the real-time video image, process the image quickly and calculate parts of the shape-structure parameters quickly. The software structure, arithmetic of image and calculation of the shape-structure parameters were introduced in this paper. The experiment results showed that the system could detect the crown and height of fruit-tree with high accuracy, which the relative error of maximal crown and height of fruittree were within -2.51% to 0% and -3.0% to 1.7% respectively. The experiment results also confirmed that the detection to density of fruit-tree basically could reflect the actual situation.
