利用方向投影算法计算仓储害虫图像倾斜角度

Compute Slanting Degree of the Stored-Grain Insects Image Based on Directional Projection

针对无明显的直线特征的仓储害虫图像,提出了一种基于整数Bresenham算法求方向投影值,利用方向投影值检测图像的倾斜角度的方法。实验结果表明,该算法能快速准确地测量出仓储害虫图像的倾斜角度,并具有很强的抗干扰性和应用适应性。

According to the feature that the Stored-Grain Insects images haven＇t the obvious lines,a new skew detection method based on directional projection is presented,using Bresenham＇s integer only line drawing algorithm. Experiment results show that the new method can measure out the slanting degree of the Stored-Grain Insects image efficiently and accurately with high noise endurance and application adaptability.
