Abstract:
1. A distance measuring device having a measuring range for measuring a distance of at least an object located in the measuring range, comprising: a light emitting component configured for emitting a light beam; a diffusing component disposed on a transmission path of the light beam, and the diffusing component being configured for transforming the light beam into a measuring light beam with a specific pattern to irradiate the object; an adjusting component configured for adjusting an incidence angle and an incidence location of the light beam striking at the diffusing component; and an image sensing component having a field of view, and the field of view covering the measuring range, wherein the image sensing component is configured for sensing an optical information of the specific pattern of the measuring light beam located in the measuring range so that the distance of the object could be calculated according to the optical information.
