STRUCTURED-LIGHT-BASED THREE-DIMENSIONAL SCANNING METHOD, APPARATUS AND SYSTEM THEREOF

摘要

A structured-light-based three-dimensional scanning method, an apparatus and a system thereof are proposed, where the method includes the following steps. Structured light with scanning patterns is subsequently projected onto a subject by a projector. When the structured light with each of the scanning patterns is projected onto the subject, images of the subject are captured by at least one image capturing device to generate an image set including the images, and tilt angles of the three-dimensional scanning system are measured by an angle detector to generate angle measurements respectively corresponding to each of the images. Whether an angle variation of the image set is too large is determined according to the angle measurements of the images therein, and the image set is flagged when the angle variation is too large. Stereo information of the subject is generated according to the image set when the image set is not flagged.
