Abstract：Aiming at the problem of visual patrol AGV navigation,a path prediction algorithm based on dynamic segmentation threshold is proposed.Based on the analysis of the visual CCD image signal,by means of the characteristics of the frame image information,the information of guide line is extracted by recursive calculation of pixel threshold.The image data binary segmentation denoising algorithm is designed.The interference caused by miscellaneous points,cross lines,light and environmental factors can be overcomed effectively,and the effectiveness of the algorithm is verified by experiments.
