摘要
文中简要介绍了ADSP-BF561的主要性能结构,并且详细介绍了均匀背景下,基于ADSP-BF561实时提取电视跟踪位置偏差的方案。实验结果表明,针对PAL制目标视频图像序列,该方案可以实时有效地提取出目标跟踪的偏差。由于采用了双缓存机制,实现了视频的实时采集与显示。
The paper introduced the main performance and structure of ADSP - BF561. The method of the extraction of the TV - tracking position deviation in a symmetrical background was described in detail. According to the experiment result based on the target video in PAL, the method can extract the tracking position deviation in time. And it was achieved to capture and display the video using the double -buffers mechanism.
