摘　　要：随机Hough变换对于实时性要求高的应用场合,仍然存在着计算速度不够快的问题。针对二次曲线检测的随机Hough变换算法,结合该算法的特点,提出其在以两片高性能的DSP芯片TMS320C6416为核心计算单元的并行C6416系统上进行快速实现的方法。该系统的核心部件-数字信号处理板处理能力强,存储容量大,结构简单、对称,易于并行实现随机Hough变换算法。在充分考虑了程序的并行性后,对一幅分辨率为800×600点的灰度图像进行1000次随机抽取,目标为二次曲线,整个检测过程需要约80ms。In the application which requests high real-time performance, there still exists a problem, that is, the calculation speed is not fast enough in randomized Hough transform. For the randomized Hough transform algorithm of conic detection and based on its characteristic, a method of its fast implementation in a parallel C6416 system which core calculation units are two high performance DSP chips TMS320C6416 is presented. The core part of this system-digital signal processing board has high performance and simple and symmetrical structure, so that it is easy to implement randomized Hough transform algorithm. With the parallelism of the routine taken into full consideration, which condition is a 800 × 600 gray image, 1000 times randomized. The whole detection process is about 80 ms.
