The invention belongs to the technical field of scanning, and particularly relates to a 3D space scanning and imaging system and an imaging method thereof. According to the space scanning and imagingsystem and the imaging method thereof, distances between points of detected objects and light sources are measured on the basis of the light interference principle, and 3D images are generated according to coordinates of the points; more specifically, two monochromatic light sources with the same frequency are emitted to the detected objects by a measuring device, bright-dark interference strips are generated when the two light sources encounter, the brightness of the interference strips of the surfaces of the detected objects is much higher than that of non-object surfaces when the light sources rotate at a certain angle, the angles of the light sources are recorded when the brightness is detected to be greater than a certain threshold value, the distances between the detected objects andthe measuring device can
