为实现桂味荔枝按种核质量进行工业分级,运用计算机视觉技术、相关分析和回归分析,计算和分析了桂味荔枝的单果质量、横纵比、容积、果顶曲率与种核质量的关系,结果表明:单果质量、横纵比、容积与种核成正相关,果顶曲率与种核质量成负相关且线性相关最显著.建立了果顶曲率与种核质量的回归模型.
In order to realize the grading of GuiZi litchi according to the seed quality, using computer vision technology, correlation analysis and regression analysis, the relationship between single fruit quality, aspect ratio, volume, top curvature and seed quality of GuiZi litchi was calculated and analyzed The results showed that there was a positive correlation between single fruit quality and lateral aspect ratio and seed volume, and the top curvature was negatively correlated with seed quality and the linear correlation was the most significant. A regression model of fruit top curvature and seed quality was established.
