| 摘 要： | 运用DSP图像处理的解决办法,设计了一套基于DSP数字图像处理技术的板带纠偏电视检测可视化系统.DSP计算速度快、可并行处理,成功解决了视频检测数据处理量大、系统实时性要求高之间的矛盾.设计中所选取的TMS320DM642芯片作为一款专用的数字多媒体处理芯片,具有丰富的外围接口和特色的视频图像采集功能,这就使该图像处理模块集成了图像的采集回放与图像处理的功能,摒弃了单独的图像采集卡,避免了数据传输过程中所出现的问题.在深入研究DSP系统的基础上,制定了系统实现的方法并在实验室条件下实现了板带纠偏与视频检测,检验结果完全能够满足实时性和精度要求. |

| Abstract: | DSP image processing solution was used to design a set of the strip correction TV detection visualization system based on DSP’s digital image processing technology.DSP’s calculation speed is quick,it can proceed parallelly,thus it is successful to solve the antinomy between the real time examination data and the real time requisition.TMS320DM642 chip was selected as a special digital multimedia processing chip, beacuse it has rich peripheral interfaces and characteristics of the video image acquisition function,which makes the image processing module integrate the image acquisition playback and image processing function, slam the door single image acquisition card,to avoid the data transmission problems occurred in the process. After deep research of DSP system,an overall program system is proposed,realizing strip correction and video detection.Experiment result indicates it can completely satisfy the request of real-time and precision. |
