摘要:
A position measurement system, includes: a plurality of concentric pattern projectors each for projecting a concentric pattern; an image sensor that has a sensor plane and that detects the concentric pattern; and an arithmetic unit that calculates a position of the image sensor and a normal direction of the sensor plane from a detection signal of the image sensor.
