1. A three-dimensional scanning image acquisition method, comprising:
synchronously acquiring a projection pattern of first wavelength light and an illumination image of second wavelength light projected on a measured object at a first moment; and
acquiring a color texture image projecting the measured object at a second moment, wherein the first moment is different from the second moment;
wherein the projection pattern of first wavelength light is used for performing three-dimensional reconstruction, and the illumination image of second wavelength light is used for assisting the color texture image in texture tracking;
the color texture image is acquired by triggering white light to be projected on the measured object, the illumination image is an image for reflecting the texture of the measured object, the illumination image is not configured to reflect a true color of the measured object.
