质心跟踪算法在小内存DSP上的快速实现
High-Speed Realization of Centroid Tracking Algorithm Used in DSP with Small Internal RAM
摘要
设计了以TMS320DM6437为核心的信标光高速探测与处理系统。由于TMS320DM6437内存较小, 片内数据内存只有128 KB,大量的数据图像无法一次移入片内RAM,这就使得现有的图像质心 跟踪算法无法在TMS320DM6437上快速运行。针对这一问题,在质心跟踪算法的基础上提出了 一种新的数据处理方法,使之在保持质心跟踪算法的跟踪精度、可靠性的同时可以高速运行在小内存的DSP系统上。
Abstract
A high-speed beacon detecting and processing system taking TMS320DM6437 as internal RAM is designed. The internal RAM of TMS320DM6437 is so small that the centroid tracking algorithm can’t run quickly. To solve the problem, a new image processing strategy based on centroid tracking algorithm is put forward, which can keep the original tracing precision and reliability of centroid tracking algorithm and can be used for a DSP system with small internal RAM.
