摘　　要：针对做前后直线运动的待检测物体,在某一个特定的时刻,可以获取该物体的上、下、左、右四个方向的图象信息,研究了这四幅同步图象的采集和预处理,并将预处理后的同步图象通过CameraLink接口上传到PC机进行后续的物体表面损伤检测。系统采用DSP+FPGA框架,利用FPGA的逻辑粘合作用完成信号格式的转换,这个方案进一步推动了机器视觉在生产领域的应用。From a moving object which is to be inspected at a special moment, four photos can be taken at the same time. This paper proposed a design which is used to capture photos and preprocessed them, after the above operation. The system submits those photos to PC through a CameraLink interface and PC processes them further. The framework of the system consists of DSP and FPGA. Using the FPGA＇s characteristic of flexible IO interfaces the design can finish the format change. It promotes the application of machine vision technology in manufacture.
