Gas Leak Inspection Using Thermal, Visual and Depth Images and a Depth-Enhanced Gas Detection Strategy

Advanced gas leak detection methods in industrial environments are of vital importance as they may translate into a reduction of accidents and increased economic efficiency. This paper proposes the use of different sensors for detecting and localizing leakages remotely, based on the measurement of variables involved when a leak is present. The processing and fusing of thermal, depth and visual images, as well as gas concentration scanning technique, is the proposed method in this article.
