Abstract:
A camera device calibration method according to one embodiment comprises the steps of: acquiring first data including location values of a first zoom lens and location values of a first focus lens, corresponding to the location values of the first zoom lens; setting at least two location points of the first zoom lens; acquiring at least two location values, which correspond to the location values of the first focus lens corresponding to at least two location points of the first zoom lens; acquiring second data corresponding to a value between at least two location values of the first zoom lens; and setting, in a camera including the first zoom lens and the first focus lens, at least two location values of the first zoom lens and the first focus lens when a difference value, which is acquired by comparing the first data with the second data, is within a preset threshold range.
