Abstract
A position control apparatus includes: a tool unit performing a work on a target object placed on a stage; a first imaging unit imaging a reference indicator set on the stage or the target object and outputting a first image; a second imaging unit imaging the reference indicator and outputting a second image; a head unit supporting the tool unit, the first imaging unit, and the second imaging unit; a calculation unit calculating three-dimensional coordinates of the reference indicator based on a first indicator image which is an image of the reference indicator captured in the first image, and a second indicator image which is an image of the reference indicator captured in the second image; and a drive control unit causing the tool unit to approach or separate from the target object based on the three-dimensional coordinates.
