Title:
【発明の名称】表面形状情報を決定する方法及び装置
Document Type and Number:
Japanese Patent JP2546885
Kind Code:
B2
Abstract:
A system determines the surface profile of an object. Systems of this kind are used in industrial robots, such as automatic welders. The severe operating environment requires a vision system with noise immunity along with accuracy. A beam splitter enables the use of discrete optical detectors which eliminate many problems inherent with previously used detectors, such as diode arrays and TV cameras. Additionally, an automatic gain control alters the intensity of a generated optical beam in response to the reflectivity of the surface. These features increase the accuracy and noise immunity of an optical vision system for use in sever industrial applications.
