ABSTRACT:
A vision sensor for tracking includes a light stripe vision sensor for use in harsh environments. This light stripe generator is light source independent and produces a light stripe without the use of lenses. Additionally, the enclosure in which the light stripe generating and detecting means are mounted includes an environmental control system which provides pressurized, conditioned air into the apparatus enclosure in order to control the affects of dust, humidity and temperature variations countered in many working environments. This vision system is particularly well suited for use in welding applications and can be easily used in combination with an industrial manipulator to provide automated vision sensor capabilities.
