ABSTRACT = {Substation inspection work plays a very important role in ensuring the normal production and the safe 
operation of a transformer substation. Use of a substation inspection robot can effectively solve the 
omission problems of a manual inspection. It can further improve the unmanned and automation of 
substation and improve security of station. A substation inspection system requires the establishment 
of a spatial position relation between the robot and the inspection object in the monitoring station. 
Key technology is the spatial location of the object being detected in the substation. The position 
of inspection object is unknown. This paper gives technical route of monocular vision positioning 
system based on switch indicator sign cooperative target. The knife switch indicator is one of the 
most important objects in the substation inspection. Usually the switch indicator lies in the middle 
or top of the substation equipment and conventional method can’t measure. This paper presents a 
substation label measurement method based on monocular vision. In this method, the label frame of 
knife switch indicator is as a cooperative target. The 3D coordinates and attitude of the label frame can 
be calculated in a camera coordinates system. At the same time, this paper introduces an extraction 
process of knife brake indicator label with multi-features under complex background. At last, we do 
simulation experiment for positioning technology of 3D virtual environment modeling system for 
substation switch indicator. Simulation results show that the method introduced in this paper can 
realize positioning of substation switch indicator label.},
