| 摘 要： | 为了在DSP平台上实时检测圆孔或圆弧图像的特征参数，介绍一种用于快速提取圆参数的基于TMS320DM642平台改进Hough变换算法。该算法利用圆的几何对称性估算待检测圆的参数。从而有效缩小参与Hough变换的参数域的范围。实验结果表明：在资源有限的嵌入式平台上，该算法计算速度快，占有内存小，检测性能好。

| Abstract: | In order to realize real-time detecting characteristic parameters of the circular hole or arc image through DSP platform,an improved Hough transform algorithm for rapid extracting circle parameters based on TMS320DM642 platform is introduced.This algorithm estimates the circle parameters by making use of the geometric symmetry of the circle,which effectively reduces the range of Hough transform parameters.The experimental results show that this method also has the advantages of high speed,small storage and ... |
