The invention discloses a vision-based AGV patrolling navigation and positioning method. The method comprises steps: an image in front of the current heading is acquired; according to first preset features of a navigation reticule, a navigation reticule object meeting the first preset features is recognized in an image; the relative position relationship between the AGV and the navigation reticule is acquired, and the relative position relationship is used for correcting the position and the heading of the AGV. An image acquisition device is adopted to replace a magnetic guidance sensor, a color adhesive tape is adopted to lay an auxiliary path, and the navigation path modification and maintenance cost is greatly reduced. In view of the shortcoming of a small viewing field of the image acquisition device, through fusing visual features and odometer information, the real-time pose of the AGV is tracked accurately. Besides, in view of accumulated errors of the odometer caused by reasons such as side slipping of a movable device and slipping of a caster, the odometer information of the AGV is corrected through setting a position correction mark with known global coordinates, and high-precision and stable AGV positioning and navigation can be realized.
