This paper presents initial work on the development of an Ultrasonic Testing (UT) system to inspect defects in the inner and outer surfaces of underwater guy wires. The methodology involves placing ultrasonic transducers adjacent to simulated sections of guy wire and the analysis of the resultant echo profiles. The goal of this work is to determine if it is feasible to use ultrasonic testing to develop...
Spatial resolution in imaging systems used for pipe inspection plays a crucial role. Catadioptric imaging systems, which normally consist of a perspective camera and a hyperbolic mirror provide a cost-effective solution. Also, they would be the imaging system of choice in confined spaces due to their size factor. In this paper we, (1) define the cylindrical spatial resolution for the pipe inspection...
Spatial resolution of imaging systems plays a major role in the design of vision-based industrial inspection systems. In this paper we formulate the cylindrical spatial resolution of a Catadioptric sensor that consists of a camera and a hyperbolic mirror for the pipe inspection applications based on the projection models cited in the literature. A laser ring is used as a structured light source for...
