基于模拟视频信号差分和射影畸变校正的图像系统
Image Processing System Based on Analog Video Signal Differential and Projective Distortion Rectification
摘要
Abstract
The video camera is widely applied to embedded systems .Before further processed by the embedded systems , the ana-log video signal is usually digitized first .The large amount of data has made the difference of the processing capability much sig-nificant, and that limits the widespread use of vision sensor .An analog video signal processing system with differential and image rectification is proposed , in which the differential between pixel in analog signal is used to detect the edge .Meanwhile, the pro-jective distortion is corrected according to lookup table .It is easier for further processing after the rectification of projective distor-tion.The solution improves the real time of signal processing and reduces the dependence on processing capability .关键词
