1. An initial setting method for an unmanned forklift, comprising:
a step of acquiring a measurement value of floor surface inclination of a stop position where the unmanned forklift stops when the unmanned forklift unloads a palette on a rack;
a step of setting the stop position where a predetermined inclination pattern is detected, as a precise adjustment position, from the acquired measurement value;
a step of causing the unmanned forklift to unload the palette in accordance with an operation program, and measuring a deviation amount of the palette unloaded by the unmanned forklift, at the precise adjustment position; and
a step of correcting a command value of the unmanned forklift at the stop position, based on the measured deviation amount.
