Orchard intelligent pesticide spraying system and method

The invention discloses an orchard intelligent pesticide spraying system and method. The method comprises the steps that a control end sends a full-automatic pesticide spraying command to a drive device, and a pesticide spraying vehicle starts a full-automatic pesticide spraying mode; a moving device advances according to a preset track based on the position information acquired by a positioning device; after arriving at the spraying area, a distance detector collects the distance to a fruit tree at the corresponding height; and when the distance between the distance detector and the fruit tree at the corresponding height is out of the preset range, a distance adjusting device adjusts the distance between a detection device and the fruit tree and the distance between a spraying device andthe fruit tree, so that the distance between the distance detector and the fruit tree at the corresponding height is within the preset range. Compared with the prior art, the pesticide spraying vehicle can achieve automatic p
