FLEXIBLE TETHER POSITION TRACKING CAMERA INSPECTION SYSTEM FOR VISUAL INSPECTION OF OFF LINE INDUSTRIAL GAS TURBINES AND OTHER POWER GENERATION MACHINERY

摘要

A camera scope inspection system with a flexible, tether mounted camera head that is maneuverable in confined internal cavities of power generation machinery. A camera head position sensing system inferentially determines the three dimension (3D) position of the camera head within the inspected machinery. Camera head position data are correlated with camera image data by a controller. In this manner correlated internal inspection image data and corresponding position data are available for future analysis and image tracking.

1. A flexible, position tracking camera scope inspection system for internal inspection of power generation machinery, comprising:
a camera scope including: a flexible elongated tether, having a distal end adapted for insertion into a blind cavity of a power generation machine; a camera head coupled to the tether distal end; an optical camera, having a field of view, coupled to the camera head, for generating image data; a camera head position sensing system for inferentially determining three dimension (3D) position of the camera head and for generating inferred camera head position data; and a controller coupled to the camera scope optical camera and the camera head positioning system, for correlating the image and position data.
