Research and Implementation of Cotton Foreign Fiber Real-Time Sorting Algorithm Based on DSP

设计了一个以高性能DSP处理器ADSP-BF533为核心的棉花异性纤维实时分拣系统,针对该系统提出了一种异性纤维实时分拣算法。该算法基于区域图像分割技术,使用乘、加和比较等运算完成棉花异性纤维的实时分拣。严格的理论推导和大量的数据实验证明,该算法相比于目前常用的基于阀值图像分割技术的分拣算法,其使用的数学模型能够更客观的反映棉纤维的数据特征,具有更高的分拣精度。同时,完成了该分拣算法向DSP硬件上的移植。经算法仿真,这种基于DSP的实时分拣算法可以很好地满足棉花异性纤维分拣系统的有效性和实时性要求。

This article will carry out a real-time sorting system for cotton foreign fiber based on highperformance DSP processorADSP-BF533and a real time sorting algorithm based on region imagesegmentation technology is proposed at the same time.The algorithm uses multiplication,addition andcomparison to complete the real-time sorting of cotton fiber.Strict theoretical derivation and a largeamount of data experiment proved that this algorithm has a higher sorting accuracy than that ofcommonly used sorting algorithm based on threshold image segmentation technology because themathematical model used in this algorithm can reflect the data characteristics of the cotton fiber moreobjectively.The sorting algorithm has been migrated onto ADSP-BF533.By algorithm simulation,thisforeign fiber sorting algorithm based on DSP can meet both validity and real-time requirement for cottonforeign fiber sorting system.
