摘要
本文描述了一个用Sobel算子实现的实时边缘检测器,该检测器以10MHZ的象素率处理电视数据,采用了流水和并行计算方式,处理一幅512×290的灰度图象需要20ms。该系统特点是速度快、造价低,实用性强,可用于实时电视跟踪,军事侦察及工业检测等系统。
This paper discribes a system whioh implements the real-time edge detector with the Sobel operator. The detector is designed to process the TV data at 10MHZ pixels rate, by using pipelined and paralleled calculations to process a 512×290 pixels grey-level image, and needs 20ms. The system is small in size, low in price and practicable in use. It may be used in real-time TV tracing military reconnaissance, and industrail inspection.
