THREE-DIMENSIONAL SCANNING METHOD AND THREE-DIMENSIONAL SCANNING DEVICE

摘要

The present invention relates to a three-dimensional scanning method capable of scanning object to be measured within a wide range, easily verifying the accurate rotation of a mirror, and easily changing a range of a rotational angle and to a three-dimensional scanning device to achieve the same. First, three-dimensional scanning method of the present invention includes a step of generating lights by using a predetermined light source, a step of projecting the lights to the object to be measured in an injection method after reflecting the lights by the mirror capable of rotating in two axial directions and rotating according to the information of the predetermined rotational angle, and a step of receiving the reflected lights from the object to be measured by using a first image sensor to detect the distances to each measurement point and directions of the object to be measured based on the photographing position of the first image sensor and the rotational angle of the mirror in accordance with the information of the rotational angle. In the step of projecting the lights to the object to be measured, the direction of the lights projected to the object to be measured is detected, thereafter, whether the rotational angle is accordance with the information of the rotational angle or not is verified based on the detected direction.;COPYRIGHT KIPO 2015
