DISTANCE MEASURING SYSTEM AND METHOD USING THEREOF

摘要

A distance measuring system includes a light emitting member, an optical member, an image sensing member, and a computing member. The light emitting member provides a light beam to an object. The optical member is disposed on a transmission path of the light beam reflected by the object. The image sensing member is disposed on a transmission path of the part of the light beam passing through the optical member, and the image sensing member has an image sensing area for receiving the part of the light beam passing through the optical member and receiving the part of the light beam not passing through the optical member. The computing member compares a difference between the deformation area and the non-deformation area of the object image so as to obtain a distance variation of the object.

1. A distance measuring system, comprising:
a light emitting member providing a light beam to an object; an optical member disposed on a transmission path of the light beam reflected by the object, wherein a part of the light beam reflected by the object is adapted for passing through the optical member; an image sensing member disposed on a transmission path of the part of the light beam passing through the optical member, the image sensing member having an image sensing area for receiving the part of the light beam passing through the optical member and receiving the part of the light beam not passing through the optical member, wherein the light emitting member partly overlaps the image sensing area, the image sensing member is used for capturing an object image from the object, and the object image includes a deformation area and a non-deformation area; and a computing member for comparing a difference between the deformation area and the non-deformation area of the object image so as to obtain a distance variation of the object.
