1. An image projection measuring apparatus comprising:
a measurer configured to measure a shape of a work by illuminating an outer surface of the work with a line laser from a laser emitter;
a storage configured to store measurement data acquired by the measurer;
an image projection data generator configured to generate image projection data from the measurement data;
an image projector configured to project the image projection data from a camera; and
an image projection controller configured to cause the image projector to project the image projection data onto the outer surface of the work,
wherein the image projector sequentially projects the image projection data corresponding to a previous measurement position onto that measurement position while the line laser is moving to a next measurement position.
