Application of  Image Processing Technology Based on DSP in the StripCorrection

Abstract

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 selcted 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.

Key words: DSP, DM642, CCD, correction system, video decoder
