Abstract: | Based on exclusive video / image processing chip DM642 and color linear array CCD TCD2252D,a real-time image acquisition and processing system were designed.Focus on the design of video buffer FIFO threshold and EDMA frame size,when using EDMA to real-time transmission image in the real-time image acquisition and processing system.This design provides a reference for high-precision measurement of object’s movement time,speed and distance. |
