OMNI-DIRECTIONAL DISTANCE MEASUREMENT DEVICE AND METHOD BASED ON STRUCTURED LIGHT USING DIFFERENCE IMAGE INTEGRAL CALCULUS ALGORITHM

摘要

PURPOSE: An omnibeary-distance facility and method using a forward direction mirror and difference image integral algorithm are provided to secure resistance to ambient illumination noises by reinforcing structured light pixels. CONSTITUTION: An omnibeary-distance facility comprises an irradiation part(110), a measuring part(130) and an analysis part(150). An irradiation part emits laser beam in a forward direction. The measuring part comprises a convex surface type mirror(131) and a camera(133). A background image is gotten repetitively from the convex surface type mirror by using camera. The analysis part calculates the object distance between the object and the camera.
