Three-dimensional scanning image acquisition and processing methods and apparatuses, and three-dimensional scanning device

A three-dimensional scanning image processing method, comprising:

• determining an image relationship between a color texture image and an illumination image;
• and
• matching the color texture image to a projection pattern for three-dimensional reconstruction of texture mapping of data according to the image relationship;
• wherein the projection pattern is acquired by projecting first wavelength light on a measured object at a first moment, and the illumination image is acquired by projecting second wavelength light on the measured object in synchronization with the projection pattern;
• and the color texture image is acquired by the projection on 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.
