Abstract: Focusing on the problem of time-consuming in the process of line structured three-dimensional target full-surface photodetection,a new line structured full-surface photodetection system adapted to the high-speed and high-accuracy needs of measurement in actual production line was designed.The flying targets were shot on distributed multi view,and then these different images were merged and the whole three-dimensional information of the measured target was reconstructed.The results show that the system is of good real time and high precision,and it can meet the practical requirements in industrial detection.
