Due to the messy logistics goods in the port area, some automatic transport vehicles often have errors in cargo transportation due to large path identification errors. Based on this, this study is based on image recognition technology, taking the most common logistics transport vehicles in the port area as the research object and using video image recognition technology as a guiding technology to perform image recognition processing on the ground guidance path. Simultaneously, this study determined the image preprocessing method which is more favorable for visual navigation, used the morphological knowledge of the image to detect the edge of the path image, then determined the position of the path center line, and carried out simulation analysis. The research shows that the results of this study have certain practicality and can provide theoretical references for subsequent related research.
