摘要
探讨了以数码图像为基础、依据特征点选取法进行株型指标计算机辅助测量的方法。通过田间实验检验该方法具有较高的准确度,进一步利用计算机图形学方法对数据进行了还原,结果基本上能够正确反映不同品种的株型特征,验证了该方法的可靠性。
On the basis of digital photograph, the computer aided plant type measurement method was studied with the way of characteristic point selection. The examination made in the field experiments sbowed that this method worked well, but because of less characteristic point, a little error may exist when this method was used in curved organs. The data revivification in use of computer graphics showed that simulated figure could indicate major characteristics of different plant types anti the credibility of this method was validated in some extent.
